Questions about USB Watchdog?

Hi all!
I am looking for a watchdog for my rig which is running under smOS from a pendrive. I can hardly find any information about them.
Can it restart my rig if the system is on a pendrive, not on a HDD or SSD?
Does it need any driver installation or just plug and play?
Is there any difference between the red, black and green ones?
black
red
green
Which one do you recommend or anything else for substitute?

3D Printed Housing for External Vive Wireless Card

Sorry I am not providing details as I want to get this info out quickly. I will respond with info if anyone shows interest, though I might be slow.
I'm not sure if anyone remembers the talk about extending the range of their Vive wireless setups. Basically, you can get a PCIe extender (built for bitcoin mining rigs I believe), and use USB 3 to move your Vive Wireless WiGig card 35 ft (CORRECTION: 20ft) to your computer. I have found that it works great for me.
But you end up with this exposed computer board just sitting there in your room with nothing to keep the board from sliding out of the extender socket and nothing to protect the board while also allowing cooling.
I took enough measurements off of the board to create a 3d model of it that captures the design information needed to create an enclosure.
I also created a 3d printable enclosure that is "good enough".
I haven't posted it because "an artist's work is never done", but if I don't post what I have, I might never post it.
So please let me know if anyone is interested in a model of the card and enclosure. Note that the enclosure is specific to the dimensions of the extender I bought, so minor tweaks might be required if you have a different extender.
Here is a picture of the final result (yes I used tape for my prototype that I never developed further)
I designed it to be modular (see the joiners I left open in the picture, in case a part of the print fails or needs fixing) and also it does not require supports. (Shakes fist at designs that require supports!)

(I would appreciate advice on how to get the image to show up in this post, I don't do this a lot)
Answers:
Here are the exact two products I bought from Amazon. No guarantees. At the time people were looking into extending the wire from the card to antenna, but my first try didn't work.
Beware, the part that you plug into your pci slot can, incredibly, be put in backwards and still fit. Also there is nothing keeping the extender in the slot.

Building my first rig with 6 GPUs using an Asus B250 MB, looking for advice

New member so please be gentle. I have been micro mining for a few months now (with my GTX 1060 and my new RTX 2080 ti) and want to step up my game a notch. I have my sites set on building the following system with the specs listed below so far. Any input on why I should not use a specific item or why I should use a certain item would be greatly appreciated!
1. Kingwin Bitcoin Miner Rig Case W/ 6, or 8 GPU Mining Stackable Frame x 1:
I have expansion in mind with this frame. It's stackable and ounces I ROI my first rig I plan on tossing a second level on to it. This frame is currently selling for around $50.

5-ALT. Sapphire Radeon Pulse RX 580 8GB (11265-05-20G) - BACKUP CHOICE GPU:
This is what I was looking at first then I found the cheaper XFX Radeon's above. These are currently running around $180.
Sapphire Radeon Pulse RX 580 8GB (11265-05-20G)

6. CPU:
Currently I do not have any CPUs in mind to use for this rig. I know I don't need a beefy CPU for running Windows. I plan on ONLY mining with GPUs in this rig. Suggestions are welcome!

7. Memory:
Currently I do not have any memory in my sites. Suggestions are welcome!

8. Harddrive:
I plan on using a simple 128GB USB thumb drive for the hard drive right now. Possibly something like an SSD if needed, but plan on using USB flash drive to start. Pros/Cons suggestions welcome!

I think I my video my endeavor and show everyone how fun/frustrating it all was. Catching all the pitfalls in hopes of helping others out etc. But first I need to have a plan and that's what this is. I need to do some lite research, get a good shopping list, make a payment plan, and an ROI schedule. Any feedback that the community could give me would be very helpful because I only know about 80% of what I need to know to build this rig. The 20% is the overclocking, bios issues (MB and gpu), and general knowledge of building a mining rig. I expect there to be pitfalls and parts I didn't think of until I start the build.

I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!

Requirements:
1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does.
**Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc*
So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though.
After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there.
Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly).
I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01
Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!!
-----How To Do This Yourself:
Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money.
Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses.
Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!)
Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!!

I have a Bitcoin Core Wallet from 2013.

So, from around 2010 to 2014 I used to mess around with mining Bitcoin. I started with CPU mining then bought a dozen of those usb asic miners then acquired a couple blade miners. My backup was to have multiple copies of my Core wallet so I wouldn't lose the coins. My failure was to keep multiple copies of the password. I used KeePass to store my password. Long story short, the KeePass database appears to be lost forever. I only know that the password is 32 characters long. By examining passwords generated by the software I can assume that it only contains no more than 3 of each characters and no two characters repeat simultaneously. It could contain upper case, lower case, and special characters.
With my video card I can only brute force 5000 passwords per second. At today's bitcoin price it is not practical to invest in more computing power but someday for my kids it could be worth it.
Right now it is just a project I am working on because these challenges intrigue me. I assume with a 12 GPU mining rig I could get more than 60,000 passwords per second but it would still be a matter of luck to crack it before I die.
...and go

I literally have tens of thousands of dollars in top-shelf hardware, looking to repurpose some before selling on eBay to build a NAS system, possibly a dedicated firewall device as well. o_O

Q1) What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.**

A1) This will be a dedicated NAS system for my home network. As such, I'm looking to have it:

- Host ##TB's of 720, 1080 & up resolution Movies and TV Shows I'm about to begin ripping from a MASSIVE DVD & Blueray collection I have.

- My kids are big on Minecraft. I understand it's possible to host your own "worlds" (or whatever they call the maps you can build) on your own "server". I think it would be pretty neat to offer them (& their friends - if can be done 'safely/securely') their own partition on one of my NAS HDD's.

- I also have accounts with a couple diff VPN companies... I understand it's possible (?) to sync said VPN's with a NAS, this might be a more relative topic on the next point/purpose...

- I'd like to be able to remotely link to this NAS for when I travel overseas and want to stream at my temp location from my house/this NAS.
______________________
Q2) What is your maximum budget before rebates/shipping/taxes?**

* A2) Here's where I make matters more complicated than most others would... I've been an advocate for Bitcoin and crypto-currencies in general since 2013. I invested in a small mining outfit back in 2014 (strictly Bitcoin/ASIC's). One of my buddies is the President of a large-scale mining operation (foreign and domestic) and he convinced me to dabble in the GPU mining-space. I made my first hardware purchase in Q4, 2017 and launched a small-scale GPU-Farm in my house since then. I had the rigs mining up until Q3 of 2018 (not cost-efficient to keep on, especially living in SoFlo) and since then, the hardware's been collecting dust (& pissing off my family members since they lost access to 3X rooms in the house - I won't let anyone go near my gear). One of my New Years Resolutions for 2019 was to clear out the house of all my mining equipment so that's all about to go up on eBay. So "budget" is relative to whatever I "MUST" spend if I can't repurpose any of the parts I already have on hand for this build... (Anyone having something I "need" and is looking to barter for one of the items I'll list later on in here, LMK).
______________________
Q3) When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.**

A3) IMMEDIATELY! :)
______________________
Q4) What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc\)**

A4) Well I had a half-assed idea approximately 1 year ago that it might be wise to build a bunch of 'gaming rigs' to sell on eBay with my intended repurposed mining hardware so I went on a shopping spree for like 6 months. That said; I've got a plethora of various other components that aren't even unboxed yet. 90% of the items I've purchased for this additional project were items that were marked down via MIR (mail-in-rebates) & what-not...
AFAIK, there are only 3X items I absolutely do not have which I 'MUST' find. Those would be - 1) Motherboard which accepts "ECC RAM". 2) CPU for said MOBO. 3) Said "ECC RAM".\* 
______________________
Q5) Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?**

A5) I'm located in Southwest Florida. No Microcenter's here. Best Buy is pretty much my only option although I am a member of Newegg, Amazon & Costco if that makes any difference?
______________________
Q6) If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.**

A6) In an attempt to better clean up this Q&A, I'm going to list the items I have on-hand at the end of this questionnaire in-case passers-by feel like this might be a TLDR.* (Scroll to the bottom & you'll see what I mean).
______________________
Q7) Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?**

A7) I don't think that's necessary for my intended purpose although - I'm not against it if that helps & FWIW, I'm pretty skilled @ this task already (it's not rocket science).
______________________
Q8) Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)**

A8) As stated in A4; ECC RAM is non-negotiable... RAID seems like a logical application here as well.

- This will predominantly be receiving commands from MacOS computers. I don't think that matters really but figured it couldn't hurt to let you guys know.\*

- I'd also be quite fond of implementing "PFSENSE" (or something of that caliber) applied to this system so I could give my Netgear Nighthawks less stress in that arena, plus my limited understanding of PFSENSE is that it's ability to act as a firewall runs circles around anything that comes with consumer-grade Wi-Fi routers (like my Nighthawks). Just the same, I'm open to building a second rig just for the firewall.\*

- Another desirable feature would be that it draws as little electricity from the wall as possible. (I'm EXTREMELY skilled in this arena. I have "Kill-A-Watts" to test/gauge on, as well as an intimate understanding of the differences between Silver, Gold, Platinum and Titanium rated PSU's. As well as having already measured each of the PSU's I have on-hand and taken note of the 'target TDP draw' ("Peak Power Efficiency Draw") each one offers when primed with X amount of GPU's when I used them for their original purpose.\*

- Last, but not least, sound (as in noise created from the rig). I'd like to prop this device up on my entertainment center in the living room. I've (almost) all of the top-shelf consumer grade products one could dream of regarding fans and other thermal-related artifacts.

- Almost forgot; this will be hosting to devices on the KODI platform (unless you guys have better alternative suggestions?)
______________________
Q9) Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?**

A9) Definitely! Desired theme would be WHITE. If that doesn't work for whatever reason, black or gray would suffice. Regarding "Case Size". Nah, that's not too important although I don't foresee a mini-ITX build making sense if I'm going to be cramming double digit amounts of TB in the system, Internal HDD's sounds better than a bunch of externals plugged in all the USB ports.
______________________
Q10) Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?**

A10) I don't know. If I do need a copy of Windows, I don't have one so that's something I'll have to consider I guess. I doubt that's a necessity though.

Needless to say, I have at least 1X of everything mentioned above. In most all cases, I have multiples of these items but obviously won't be needing 2X CPU's, Cases, etc...

Naturally, I have GPU's. Specifically;

At least 1X of every. Single. NVIDIA GTX 1070 TI (Yes, I have every variation of the 1070 ti made by MSI, EVGA and Zotac. The only brand I don't have is the Gigabyte line. My partners have terrible experience with those so I didn't even bother. I'm clearly not going to be needing a GPU for this build but again, I'm cool with discussing the idea of a barter if anyone reading this is in the market for one.

I also have some GTX 1080 TI's but those are already spoken for, sorry.

It's my understanding that select CPU's I have on this list are ECC Friendly and AFAIK, only 1 of my MOBO's claims to be ECC Friendly (The ASROCK AB350M PRO4), but for the life of me, I can't find any corresponding forums that confirm this and/or direct me to a listing where I can buy compatible RAM. Just the same, if I go w/ the ASROCK MOBO, that means I'd be using one of the Ryzens. Those are DEF. power hungry little buggers. Not a deal-breaker, just hoping to find something a little more conservative in terms of TDP.


In closing, I don't really need someone to hold my hand with the build part as much as figuring out which motherboard, CPU and RAM to get. Then I'm DEFINITELY going to need some guidance on what OS is best for my desired purpose. If building 2X Rigs makes sense, I'm totally open to that as well...
Rig 1 = EPIC NAS SYSTEM
Rig 2 = EPIC PFSENSE (or the like) DEDICATED FIREWALL

Oh, I almost forgot... The current routers I'm using are...

1X Netgear Nighthawk X6S (AC 4000 I believe - Router dedicated towards my personal devices - no IoT &/or Guests allowed on this one)
1X TP-Link Archer C5 (Router). Total overkill after implementing the Nighthawks but this old beast somehow has the best range, plus it has 2X USB ports so for now, it's dedicated towards my IoT devices.
---- I also have a few other Wi-Fi routers (Apple Airport Extreme & some inferior Netgear's but I can only allocate so many WiFi Routers to so many WiFi channels w/out pissing off my neighbors) On that note, I have managed to convince my neighbors to let me in their house/WiFi configuration so we all have our hardware locked on specific, non-competing frequencies/channels so everyone's happy. :)


Please spare me the insults as I insulted myself throughout this entire venture. Part of why I did this was because when I was a kid, I used to fantasize about building a 'DREAM PC' but could never afford such. To compensate for this deficiency, I would actually print out the latest and greatest hardware components on a word document, print the lists up & tape to wall (for motivation). I was C++ certified at the age of 14 and built my first PC when I was 7. At the age of 15 I abandoned all hope in the sector and moved on to other aspirations. This entire ordeal was largely based off me finally fulfilling a childhood fantasy. On that note = mission accomplished. Now if I'm actually able to fulfill my desires on this post, I'm definitely going to feel less shitty about blowing so much money on all this stuff over the last couple years.

TIA for assisting in any way possible. Gotta love the internets!


THE END.
:)

EDIT/UPDATE (5 hours after OP) - My inbox is being inundated with various people asking for prices and other reasonable questions about my hardware being up for sale. Not to be redundant but rather to expound on my previous remarks about 'being interested in a bartetrade' with any of you here...

I did say I was going to sell my gear on eBay in the near future, I also said I wanted to trade/barter for anything relative to helping me accomplish my OP's mission(s). I'm not desperate for the $$$ but I'm also not one of those people that likes to rip other people off. That said; I value my time and money invested in this hardware and I'm only willing to unload it all once I've established I have ZERO need for any of it here in my home first. Hence my writing this lengthy thread in an attempt to repurpose at least a grand or two I've already spent.

One of the most commonly asked questions I anticipate receiving from interested bodies is going to be "How hard were you on your hardware?" Contrary to what anyone else would have probably done in my scenario which is say they were light on it whether they were or weren't, I documented my handling of the hardware, and have no problem sharing such documentation with verified, interested buyers (WHEN THE TIME COMES) to offer you guys peace of mind.

I have photo's and video's of the venture from A-Z. I am also obliged to provide (redacted) electricity bill statements where you can correlate my photo's (power draw on each rig), and also accurately deduct the excess power my house consumed with our other household appliances. Even taking into consideration how much (more) I spent in electricity from keeping my house at a constant, cool 70-72F year-round (via my Nest thermostat). Even without the rigs, I keep my AC @ 70 when I'm home and for the last 1.5-2 years, I just so happened to spend 85% of my time here at my house. When I would travel, I'd keep it at 72 for my wife & kids.
Additionally; I had each GPU 'custom' oveunderclocke'd (MSI Afterburner for all GPU's but the EVGA's).*
I doubt everyone reading this is aware so this is for those that don't.... EVGA had the brilliant idea of implementing what they call "ICX technology" in their latest NVIDIA GTX GPU's. The short(est) explanation of this "feature" goes as follows:

EVGA GPU's w/ "ICX 9 & above" have EXTRA HEAT/THERMAL SENSORS. Unlike every other GTX 1070 ti on the market, the one's with this feature actually have each of 2/2 on-board fans connected to individual thermal sensors. Which means - if you were to use the MSI Afterburner program on one of these EVGA's and create a custom fan curve for it, you'd only be able to get 1/2 of the fans to function the way intended. The other fan simply would not engage as the MSI Afterburner software wasn't designed/coded to recognize/ communicate with an added sensor (let alone sensor'S). This, in-turn, would likely result in whoever's using it the unintended way having a GPU defect on them within the first few months I'd imagine... Perhaps if they had the TDP power settings dumbed down as much as I did (60-63%), they might get a year or two out of it since it wouldn't run as near as hot, but I doubt any longer than that since cutting off 50% of the cooling system on one of these can't be ignored too long, surely capacitors would start to blow and who knows what else...
(Warning = RANT) Another interesting side-note about the EVGA's and their "Precision-X" OveUnderclocking software is that it's designed to only recognize 4X GPU's on a single system. For miners, that's just not cool. My favorite builds had 8X and for the motherboards that weren't capable of maintaining stable sessions on 8, I set up with 6X. Only my EVGA Rigs had 3 or 4X GPU's dedicated to a single motherboard. Furthermore, and as stated in an earlier paragraph, (& this is just my opinion) = EVGA SOFTWARE SUCKS! Precision X wasn't friendly with every motherboard/CPU I threw at it and their extension software for the CLC Close-Loop-Cooling/ CPU water-coolers simply didn't work on anything, even integrating into their own Precision-X software. The amount of time it took me to finally find compatible matches with that stuff was beyond maddening. (END RANT).
Which leads me to my other comments on the matter. That's what I had every single 1070 ti set at for TDP = 60-63%. Dropping the power load that much allowed me to bring down (on average) each 1070 ti to a constant 110-115W (mind you, this is only possible w/ "Titanium" rated PSU's, Platinum comes pretty damn close to the Titanium though) while mining Ethereum and was still able to maintain a bottom of 30 MH/s and a ceiling of 32 MH/s. Increasing the TDP to 80, 90, 100% or more only increased my hashrates (yields) negligibly, like 35-36 MH/s TOPS, which also meant each one was not only pulling 160-180W+ (Vs. the aforementioned 115'ish range), it also meant my rigs were creating a significantly greater amount of heat! Fortunately for the GPU's and my own personal habits, I live in South Florida where it's hot as balls typically, last winter was nothing like this one. Increasing my yields by 10-15% didn't justify increasing the heat production in my house by >30%, nor the added electricity costs from subjecting my AC handlers to that much of an extra work-load. For anyone reading this that doesn't know/understand what I'm talking about - after spending no less than 2-3 hours with each. and. every. one. I didn't play with the settings on just one and universally apply the settings to the rest. I found the 'prime' settings and documented them with a label-maker and notepad. Here's the math in a more transparent manner:

*** I NEVER LET MY GPU's BREACH 61C, EVER. Only my 8X GPU rigs saw 60-61 & it was the ones I had in the center of the build (naturally). I have REALLY high power fans (used on BTC ASIC MINERS) that were sucking air from those GPU's which was the only way I was able to obtain such stellar results while mining with them. **\*
Mining at "acceptable" heat temps (not acceptable to me, but most of the internet would disagree = 70C) and overclocking accordingly brings in X amount of yields per unit. =
'Tweaking' (underclocking) the GPU's to my parameters reduced my yield per unit from -10-15%, but it SAVED me well over 30-35% in direct electricity consumption, and an unknown amount of passive electricity consumption via creating approximately 20%+ less heat for my AC handler to combat.

I say all this extra stuff not just for anyone interested in mining with their GPU's, but really to answer (in-depth) the apparent questions you people are asking me in PM's. Something else that should help justify my claims of being so conservative should be the fact I only have/used "Platinum and Titanium" rated PSU's. Heat production, power efficiency and longevity of the hardware were ALWAYS my top priority.* . I truly thought Crypto would continue to gain and/or recover and bounce back faster than it did. If this project had maintained positive income for 12 months+, I'd have expanded one of our sites to also cater to GPU mining on a gnarly scale.

Once I have my NAS (& possibly 2nd rig for the firewall) successfully built, I'll be willing/able to entertain selling you guys some/all of the remaining hardware prior to launching on eBay. If there's something you're specifically looking for that I listed having, feel free to PM me with that/those specific item(s). Don't count on an immediate response but what you can count on is me honoring my word in offering whoever asks first right of refusal when the time comes for me to sell this stuff. Fortunately for me, PM's are time-stamped so that's how I'll gauge everyone's place in line. I hope this extra edit answers most of the questions you guys wanted to have answered and if not, sorry I guess. I'll do my best to bring light to anything I've missed out on after I realize whatever that error was/is. The only way anyone is getting first dibs on my hardware otherwise is if they either offer compelling insight into my original questions, or have something I need to trade w/.

THE END (Round#2)

PCI-e to USB Card Passthrough Suggestions

My POS motherboard only has ONE usb controller, which means I'm unable to pass it through to my Windows gaming VM. I need to do this as my Xbox wireless adapter is really wonky with just USB passthrough, and the only way to get around this is to passthrough an entire USB controller. Pretty sure this is a KVM issue as I've never had any issues passing through USB devices on ESXi.
I have an mATX build with a huge graphics card, so my PCIe x2 slots are blocked off, but I managed to use one of those bitcoin mining rig extender cables to "breakout" the slot. My inelegant plan is to just get a PCIE to USB card and mount it externally.
Anyone have any suggestions for a good card that works with unRAID? I see a lot of cheap options on eBay/Amazon. Used server grade cards would be ideal.
I'm even open to alternate suggestions. Things I've thought about:

Need some troubleshooting help! Riser 008s and R3c

This project isn't for gpu mining but I know these risers are mainly used for this purpose so I thought I might get some good feedback here. My project is that I have an itx board with a single x16 pcie slot. It also has 3 m.2 pcie gen3 x4 slots. I have one free m.2 slot and wanted to convert that to x16 via riser. I wanted a 2nd low power silent gpu added to the rig. I went with the fanless msi 1030. It has a max draw of ~30w so I figured sata power would be safe. I purchased this and this to test with. Neither work!! So it must be something on my end?? The first part is fairly standard, the difference being I'm going to a m.2 slot where most of you are coming from x1 or x4. "In theory" this should just work! I'll start with the 2nd part since it's very simple: m.2 connector -> x16 socket + sata power. I hooked this up, seated the gpu and booted up. Nothing. Not even bios. I pulled the gpu and booted. Bios worked and booted up (running a 1080ti direct on the board). Installed the gpu back and nothing. I bought the 1030 used so I pulled the 1080ti and installed the 1030 direct to the mb. Works! So then I thought maybe the riser is bad or that sata power is insufficient seeing that most gpus would also have 6+8pin direct whereas mine has no external power. So I swapped risers out. This time the 008s with additional power connectors. Exact same thing. First I powered via pci only. Then sata+pci. And finally sata+pci+molex. In all situations the red led lit up. In all situations if I do not have the gpu plugged in it boots up fine. The strange thing is I never get into bios. No speaker or post lcd on this board so my troubleshooting is limited. And to note I test both gpu hdmi ports just to make sure one vs the other was set to primary. I got lazy and just looked at my mouse to light up to see if it booted. The mouse stayed dark, implying it never posted. Any help would be greatly appreciated! solved I have two m.2. ports which are pcie only. I have 1 port that is pcie/sata. the suggestion by u/sqrtlurface was to use the pcie/sata port and now the 1030 is being recognized in both linux and windows.

/r/Monero - Newcomers Please Read. Everything You Need To Know.

What is Monero (XMR)?
Monero is a secure, private, untraceable (crypto-)currency. It is open-source and freely available to all. Don't believe us? Click here.
Monero is a tool that people can actually use. It makes receiving payments hassle-free, since merchants and individuals no longer need to fear the source of funds they are accepting. With transparent systems like Bitcoin, Ethereum, Verge, or Dash, these people need to hope (or spend substantial resources verifying) the sender did not use the funds illicitly. Furthermore, merchants do not want all their vendors known, and individually do not want everyone to know how much they are spending. If I spend more than I should at Newegg (store), that's my own business.
Monero is different because every transaction is always private. There is no way for pools and exchanges to opt out of sending private transactions. Thus, Monero's anonymity set far exceeds any other coin's anonymity set. Over 86,000 transactions in the past month of August, 2017 hid the sender and receiver, and about 99.95% of them also hid the amount (will increase to 100% of all new transactions in September)! There is no suspicion in using a private transaction, since all transactions are private. A single transaction does not stick out.*
This privacy is afforded with the best technology. I implore you to take a few minutes to learn about the four main technologies that Monero uses to provide privacy:
There are several other things that make Monero great! It has a smooth tail emission, dynamic blocks and fees, and an accessible Proof of Work (mining) algorithm.
*You can optionally choose a very large, unusual ringsize to make the transaction stick out. This is not recommended, and normal users who leave the ringsize at the default setting will not experience any issues. Also, it's possible for a user to manually add identifying information to the tx_extra field, which is something that a user must seriously go out of their way to do.
Now you know Monero (XMR) has the best technology. What else makes Monero (XMR) different than other cryptocurrencies?
P.S. Want a quick-start, simple your-grandma-could-do-it guide? Here's a great one!
Am I a bad person to consider using this?
No, Monero is freedom money. You can do whatever you want with it, whenever you want, where ever you want. We make it clear that you should own your wealth 100%. What you do with it, is none of our concern.
Where does the word Monero come from?
The word Monero comes from the language Esperanto. Monero means coin oand currency. The plural way of saying Monero in Esperanto and in our cryptocurrency is Moneroj.
How do I store Monero?
Monero Core
Monero Core GUI (If you don't know how to use it, click here for instructions and tutorial)
Monero Web-Wallet
Offline Wallet Generator
Is there a lightweight wallet for Monero?
Not yet, but you can use the official GUI with a remote node.
Are there any other ways to store Monero (XMR)?
Yes, there are many mobile wallets out there that allow you to store Monero (XMR). We do not recommend them, because they are not official releases of Monero. If you do decide to use other wallets, please make sure to do your research first before storing any Moneroj in the wallet. Anything used for Monero outside of official releases, will be used at your own risk. Some may be used for scamming purposes. If you still decide to take the risk; do not use them for large amounts. Also keep in mind that there is a high chance that Monero support will not be able to help you if you bump into any problems from applications outside of official releases. Why should you not use non-official wallets? Well would you buy a house and give your only key you have to the buildemanagement and wait for him/her to open the door to the house you supposedly own? No. Same goes with cryptocurrencies. You should always have possession of your private keys, and your Moneroj. Most non-official releases own your private keys, therefore you do not own the Moneroj.

ethtrader Glossary of Terms

I recently introduced a friend to our humble, little subreddit and they quickly pointed out that the language spoken here did not appear to be English. I suppose we do toss around a fair amount of acronyms, memes, and slang. I put together a quick glossary of terms for them and figured I should post it here in case any other new ethtraders can benefit from it:

I hate my Fucking Mining Rig - Short Story of my mining adventure (Don't really hate it)

Wanted to write a short write up on my journey of Crypto mining for some of the newer people and people who want to get into it. Not trying to discourage anyone from starting, but want to show the progression of a newbie.
So I am a good with computers and learned of Bitcoin when it was about $7 a coin. Laughed at the idea of some computer doing some math and getting some BS currency. Million dollar mistake on my part, but hindsight is always 20/20.
Anyways, Learned about ethereum in May. Bought some at around $180 and bought all the way up to $330. Now to the mining rig. Ran all of the calculations and with a 180 hashrate and 900 watts I was gonna get 6-7 Eth per month. Shit was gonna be profitable in under 3 months. I was gonna be a fucking crypto allstar and be rich as fuck!
Bought all of my parts literally the day before they were nonexistent. Literally bought the last RX480's from Amazon. Here is a list of my parts.
Asrock board Pentium dual core processor 4 Gb of ram 128 gb SSD 1200 watt Rosewill PSU 6 Sata to Molex PCI Risers (Junk) 6 RX480's - 2 Asus Strix, 4 Gigabyte Total cost - Roughly $2,500 (Pennies compared to my future ROI)
Please keep in mind that I am not posting every single miner issue that I ran into such as fucking with Wattman for a few weeks before learning about Trixx and Afterburner.
I've built computers before, so that part wasn't hard. Set everything up and get windows 10 running.
Problem 1 - Computer doesn't see all of the cards. Had to run the drivers a few times and tweak some shit, but got all 6 cards seen.
Miner hurdle (See what I did there) but off to the races. Let's get this bitch running so I can begin planning my retirement.
Get Claymore running, Got Trixx to overclock. Ran my cards at -96, 1200, 2200 fans at 85% (Cause I'm cool like that.) Major stability issues from the start. 1 card (Asus) would crash all the time. Didn't know about the watch dog feature in claymore that would restart my rig when a card crashed. Great feature but my computer would go into this state of having power, but not loading the operating system. Even if it did restart, most of the time claymore would get stuck right before setting the dag's and would just lock up. (Claymore program is awesome by the way, this was my rigs fault)
Could not get this fucking Asus card to stop crashing, even on stock settings. Sent the bitch back RMA style. Asus said something was wrong and sent me a new one.
Awesome, lets get this bitch running. I need to start looking at sick houses in Costa Rica to move to once I am rich as Fuck!
New card makes things better for a few days. Not 100% stable but better. Go to vegas for a driving thing (Race cars - Future rich guy stuff) and this mechanical demon starts crashing every few hours. Luckily I had Google remote desktop installed so I could log on and restart it or change settings in Trixx. Had to have my GF unplug it and plug it in a few times.
Get back home, fuck with this thing but still random crashes on random cards. Decide it is the PCI risers. Contact seller who will send me some more for free. Slow boat from china took two weeks to get them. They arrive but still some of them are bad. Can't seem to piece together 6 good ones.
Did some research online (Ethereum Forum and Reddit) and decided to get some new style of risers V007 6 Pin to Sata ($70) and they take a month to get here. Plug them all in and they seem to be working much better. Decent stability, But I ain't got time for fucking stock bios. Let's ramp these bitches up and get 32 MHs per card at 600 watts from the wall!
Actually flashing the bios was pretty easy. Thank you 6 pound 9 ounce baby jesus! Long story short had some major stability issues and bounced around with some different timing straps before finding the right ones. (Uber 3.1 for Samsung memory)
So now that we've got some good hash speeds and decent stability let's ramp this private ATM up a little bit by dual mining some Decred. Get dual mining up and running. go to sleep. Wake up the next morning expecting to see myself on the top 100 forbes list. look at my mining rig stats on my phone and see that it died roughly and hour after I went to sleep. Walked toward my rig on the red carpet I had just installed and saw that it was off. Flicked on the light to check it out. No light, WTF? Well I'll be god damned, no power in this whole fucking room. Checked my breakers and sure enough this metal motherfucker tripped my breaker.
No worries though. I'm smart as fuck. I'll just undervolt the shit out of it to get the power down. No way in hell I am just mining ether. I'm going balls to the wall!
As you can expect I had many days of stability issues and tripped breakers. But fuck it, I have homeowners insurance. Burning it to the ground will be covered. (Didn't happen)
My surge protector must be maxed out. Let's buy a bigger one ($25). Same issues.
Fuck Decred, I'll mine SIA, less power. Damn I'm smart.
Rig is more stable with Sia and no tripped breakers. Family medical emergency, have to fly north for a few days. But my rig has been fairly stable and I've got remote desktop if anything goes wrong.
Arrive at airport, check mining stats, rig is down. No worries remote desktop. FUCK, not responsive, no way to remote into the rig and no way to remotely power it off and on.
Lost 4 days of mining. But no worries the difficulty is only, Holy shit that's high! But the price of Ether will make up for it. Ether crashed to the $200's. Oh well, maybe a 10 room house in Costa instead of a 12. No sweat.
Get back to my house and this whore of a machine is just sitting there in a computer coma. It's on but it's not. LED lights glaring at me like "Fuck you human, I ain't doing your stupid math problems!" Fuck you machine, I'm your master. You will do my math problems and you will fucking like it.
My AMD Drivers seem to disappear and the computer goes into a coma like state. Someone on Reddit suggested using the 16.9.2 drivers. Installed and they worked better.
Still random crashing. This shitty PSU must be maxed out. Fuck you PSU, I'm getting you a little brother (EVGA 750 gold $120.)
What do you mean you have to jerry rig a second PSU so it starts without being connected to a motherboard? 2 more hours of my life wasted.
But finally some stability. On my way to being fucking rich. I start looking at people in bentley's and can only laugh. You dumb fuck, I'm gonna be way richer then you. Gonna get a Bugatti for each day of the week.
Damn this difficulty is a bitch. Fuck you Genesis Mining and your pallets of GPU's. You're killing me smalls!
But anyway, on my way to rolling around in my fuck you money!
Fuck you dag file 135, you're killing my future millions. Fuck you dag 138, you dropped me to 167 mhs.
Thank god AMD was there to save my ass with their dope ass blockchain drivers.
download, run DDU, Restart, install drivers, restart, run pixel patch, restart. Perfect, I'm in the money now! I can taste the caviar and champagne already.
Now my cards only run 4 Mhs each. WTF? Try a bunch of the other new drivers. Same shit. Roll back to 16.9.2 and they run fine, just at 167 instead of 180.
Someone on a forum said he had the same issue and did a fresh install of windows 10 and it worked.
So I'll just reformat my SSD (Windows wouldn't do a fresh install within the operating system. Fuck you Bill Gates! Gonna buy you once I get this thing running at 180.)
Format SSD, plug back in, throw in my gangster ass boot USB drive. Ramdisk error. Fuck you Bill Gates! Reformat SSD multiple times, lots of forum reading. Install windows from another computer through command prompt (I'm a coder now as well.) This shit has got to work, I did it in command prompt bitches!
Same fucking error. Now down to an 8 bedroom house in Costa and only 6 Bugattis.
Let's try unplugging my 6 cards and see if that works. Thank you 6 pound 9 ounce baby jesus. Windows installed.
New drivers work and I'm back at 180! Raking in the cash now.
With those speeds my Asus cards crashed. Had to dial down the hashrate to 177.5 for them to be stable. So now going to use some commands in claymore to run the Asus cards at lower speeds while letting my other cards mine harder.
I wrote this to let people know that mining isn't all Bugatti's and caviar. These machines are fickle little cunts that do what they want. No system is the same. So when you post on a forum, people will give you advice on what may work. But what works for them, may not work on your rig. In the end it's up to you to figure it out.
I have spent countless hours after work and on weekends working on this bitch. Hell I've probably spent a few hours just staring at it and thinking about all of the ways I could destroy it slowly.
While I love Etheruem and do value the knowledge gained, I would have made more money just buying Eth and holding.
The guys you see on youtube building sick rigs with crazy specs have been at it for a while. They have worked through the process and know how to solve all of the problems. You have not and will have to work them out on your own.
My whore of a rig will pay for itself soon. But I would suggest that if you want to start building a new mining rig. Check the difficulty chart and make sure you have tons of free time to fuck with it.
I'd post my wallet address for donations since I just saved you $2,600. But I am afraid hackers will steal my monies :)
Hope you enjoyed my mining life story from the past few months.

How To Invest in Cryptocurrencies: The Ultimate Beginners Guide

All statements are based on the author’s experiences. I take pride in informing the public and helping as many as I can through sharing my experiences with my readers. That said, no one except you can take responsibility for your Cryptocurrency Investing decisions, so do think it through before investing.
If you would like to learn more about the techlogogy behind cryptocurrencies, please check out our blockchain courses on crypto.
When I first started taking an interest in cryptocurrency I thought I was so lost in this huge sea of unknowns. Where do I start? What are the useful keywords to look up and keep in mind? What are the available helpful resources? This cryptocurrency investing guide is written so that in just 20 minutes, you would have a sense of what to expect of your upcoming crypto journey, and how to best go about starting it. Enjoy it, it might just be the most exhilarating ride of your life.

Rise of the Cryptocurrencies
As the tech literacy of the population increases, acceptance of crypto as a legitimate store of value follows, and it boomed. Titles along the lines of ‘Bitcoin price hits new all-time high’ and ‘Ethereum price surges’ are starting to perforate the general public’s news feed. What we know for sure is that people who were once skeptical of Bitcoin and the technology behind it are slowly understanding and getting increasingly involved with crypto. As at the time of writing, the market cap of the entire crypto space is at 30.9 billion USD. It was 20 billion just four months ago. What would it be four months from now?
Current Makeup of the Cryptocurrency Space
You would have heard of Bitcoin and the ‘altcoins.’ How this naming convention started was because back in the days of 2011, forks of Bitcoin appeared in the markets. The forks, or clones, each aspire to serve a niche area, aiming to be ‘better’ than Bitcoin. Since then countless new crypto has emerged, eroding away Bitcoin’s crypto market cap dominance. These altcoins are gaining market share at an alarming speed. Ten times or more growth has been observed in a time span as short as six weeks (see PIVX, an altcoin).
Cryptocurrency, Stocks, and Fiat
The currencies we know are referred to as ‘fiat’ by the cryptocurrency community. Although having ‘currency’ in its name, cryptocurrencies share more similarities with stocks than currencies. When you purchase some cryptocurrency, you are in fact buying some tech stock, a part of the blockchain and a piece of the network.
Cryptocurrency Exchanges
The most common place where people buy and trade cryptocurrency is on the exchanges. Exchanges are places where you may buy and sell your crypto, using fiat. There are multiple measures to judge the reliability and quality of an exchange, such as liquidity, spread, fees, purchase and withdrawal limits, trading volume, security, insurance, user-friendliness. Out of all these, I find Coinbase as the best exchange hands down. It has a beginner-friendly user interface, and an unbeatable 100% crypto insurance.
After setting up an intermediary bank account and verifying your details with Coinbase, you are only five simple steps away from a Bitcoin purchase:
  1. Access the ‘Buy/Sell Bitcoin’ tab
  2. Select the payment method using the drop-down menu
  3. Enter the desired amount
  4. Click ‘Buy Bitcoin Instantly.’
  5. View your credited Bitcoins on your dashboard
When you get acquainted with buying crypto and start to itch for some crypto trading (e.g. BTC/ETH), simply perform an instant transfer from Coinbase to GDAX free of charge and start trading. Think of Coinbase as the place to conveniently buy and store your crypto and GDAX as your margin trading platform. Transfers between the two are instant and free.
As you slowly get familiar with other currencies, you might want to have the option of investing in them. Bittrex and Polo are two exchanges that offer a wide selection range.
When signing up on these exchanges for the first time, do make it a point to verify your account with the required documents early, as you do not want to be caught in the middle of some tedious and slow admin work when the trading opportunity comes. Verification on these exchanges may take days, and purchase/withdraw limits may only increase gradually as you trade.
An additional point to note: if you are using a currency other than USD, do check out the exchange’s ease of funding and withdrawal. You do not want your exchange to come into fiat withdrawal problems like Bitfinex did recently.
Cryptocurrency Wallets
Exchanges have inbuilt online wallets to keep the cryptocurrency you purchased. However, for those who heard of the Mt. Gox hack, you might feel uneasy to put on an exchange. If you do not wish to keep your crypto holdings on the exchange, you have the option to either use a paper wallet service like myetherwallet.com or spend 99 USD on a hardware wallet like KeepKey. Both serve the purpose of removing platform risk, at the cost of taking up the responsibility of keeping your cryptocurrency safe.
To transfer your crypto from exchanges to your hardware wallet for long term storage, simply follow these steps, using Coinbase and KeepKey as an example:
  1. Plug in your KeepKey USB cable
  2. Open your KeepKey Client (on Google Chrome under Apps)
  3. Find your wallet address on the KeepKey Client UI
  4. Access Coinbase ‘Send/Request’ tab and input your KeepKey wallet address
  5. Confirm amount and click ‘Send Funds’
Take note to first send a tiny amount (e.g. 0.0001 BTC) for testing before sending the bulk, lest an error occurred and the transfer amount is lost. A small network transfer fee might be charged.
Personally, I own a hardware wallet, as I love the feeling of a having around a tangible reminder of my crypto holdings. Also, the hardware wallet’s user interface makes it easy to keep multiple coins, which is especially handy when you participate in ICOs (Initial Coin Offering) in the future.

Cryptocurrency as a Percentage of Your Investment Portfolio

This part will be wildly subjective. Crypto has the potential to realize many ‘rags to riches’ stories, but its volatility makes it unpredictable. As a precaution, the money you put in crypto should be money that you are fine with losing. I cannot emphasize the importance of this as we often underestimate how the volatility affects our emotional capacities. The upside is huge, but it comes with lots of risks and, if I may put it, emotional torment.
A conservative portfolio I would suggest is as follows:
< 30 years old (max) 30% Crypto, 50% Traditional Investments
30 – 40 years old (max) 20% Crypto, 60% Traditional Investments
> 40 years old (max) 10% Crypto, 70% Traditional Investments
This is not meant to be age discriminatory but considers the fact that one takes up more financial responsibilities (mortgage, family) as he grows older.
Within the designated crypto share of your portfolio, you may diversify your coins based on your risk appetite.

Show Me the Money! Cryptocurrency Investing

Now, this is where it gets exciting.
How do we pick the winner? How do we avoid picking the loser?
Note that crypto is now in a huge bull market and anything could rise over time. Also, do not dismiss the possibility that we may be in a bubble like the-dot-com boom back in 2000. Still, ask yourself these questions before you decide to invest in a coin:
Short Term Trading with Margin
Once you get familiarized with crypto, you may want to trade on your ‘stash’ in hopes of increasing it. For the experienced forex traders, this is nothing new. But for the new crypto investor, you may want to brief up on how to make a leveraged trade.
Short-term trading takes advantages of incoming news to make a quick buck. If you foresee good news from an upcoming release of a coin, you may want to open a long and see how it goes. Remember, buy the rumor, sell the news; act fast and be daring if you wish to make a profit with short term trading.
Mining
For those who are more comfortable with a predictable form of reward, mining is the way. Mining involves setting up of a rig, consisting of GPUs or CPUs and an investment in the electricity. Mining is only possible on cryptocurrencies that follow the Proof of Work protocol. It takes some effort to setup and gets things running, but it is attractive as a long-term passive income as long as you frontload the work.
Staking
Staking is the Proof of Stake version of ‘mining.’ Think of this as making dividends on your stock. The reward rate and staking method differ greatly among Proof of Stake coins, but in general, it takes less effort as compared to mining.
Arbitraging
As you get a hand in multiple exchanges, you may wish to buy from one exchange and sell on another to make ‘arbitrage’ gains when you spot an arbitraging opportunity. Take note of two things if you wish to do so: remember to factor in fees, and remember that the price could change when you are transferring your coin between exchanges, especially during volatile times. USD tends to be liquid so this happens less for it, but for other currencies such as CAD (Canadian dollar) and SGD (Singapore dollar), there may exist more arbitraging opportunities to exploit.
That’s about all I have, for now, invest smart and most importantly, don’t forget to have fun!

UpgradeMeAPC? Hoping to (re)build a "do-everything" PC; what devices might I need, and need to upgrade?

I already have a desktop PC, but I am planning a summer project with my roommates to upgrade some of it and have a wall-mounted, water-cooled, monster-of-a-machine that essentially "does everything," within relatively-sane reason. The wall mounting is completely up to us and still in the planning stages, but the advantage here is that it allows us to craft a case that can potentially fit all kinds of neat things in/on it, from the watercooling rig we're looking into to the buttload of additional drives (hard drives and otherwise) we may want to stick onto it.

"Does everything" essentially means that we'd be hoping to be able to do effectively anything from game, burn CD/DVD/Blu-Ray discs, read ZIP (yep, we still have some of those around) and 5.5"/3.25" disks, "professionally" (one of us is a graphic designer for a local magazine, so there's that) edit photos and video, record home-studio-quality sound (I record audiobooks for my students, for example), maybe even mine bitcoin (lol?) and more.

Some of the parts I have already include:
- GeForce GTX 1080 G1 ( https://www.amazon.com/gp/product/B01GJEE9BG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 , probably need a better one or a second one if we do the bitcoin....erm...thing. This is probably the part I'm least willing to upgrade, as they tend to be the most expensive, but I'm still all ears)
- Intel Core i5 660K 3.5GHz CPU ( https://www.amazon.com/gp/product/B012M8M7TY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 , could maybe upgrade)
- Corsair Vengeance LPX 16GB DDR4 D2666MHz C16 memory ( https://www.amazon.com/gp/product/B0123ZC44Y/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 , definitely open to upgrading this)
- ASUS Z170-A Mainboard ( https://www.amazon.com/gp/product/B012NH05UW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1, likely need to update this based on our "needs" for the build we're hoping to accomplish )
- FocusRite Scarlett Solo USB Audio Interface ( https://www.amazon.com/gp/product/B01E6T56CM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 )
- Behringer B-1 Condenser Microphone ( https://www.amazon.com/gp/product/B0002KZAK8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 , also have a pretty nice stand and filters for it but am open to further suggestions. Not looking to upgrade the microphone itself but if you want to recommend a nice desktop stand for it, or cables, or pop filters, or whatever, I'm all ears!)
- 5-port PCI USB ( https://www.amazon.com/gp/product/B01LZWC7TL/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1, willing to upgrade if this one happens to be a piece of junk )
It also has two internal hard drives (I can upgrade these how/whenever, doesn't really matter right now but I'm looking for high-capacity recommendations), and a whole lot of USB interfacing (keyboard and mouse are separate, microphone is another, have an external blu-ray drive, a Bluetooth USB dongle, a Playstation DexDrive, and more).
Recommendations for layouts are absolutely welcome (like I said, we're still just planning right now) and for other components like fans and watercooling components are also welcome and appreciated. We're not flying blind, but we ARE flying with essentially just guidance from Google and what other subreddits turn up.

I'm not super sure where or how to start, since the PC I have now is the first PC I've built since 2000, so any help is appreciated!

How to get $100 million in VC funding to build an industry that makes $300 million profit without spending a dime

Yesterday I received an unexpected gift: a link to a copy of the slides of the presentation that 21inc gave to investors, apparently between October and December 2014, when they were still calling themselves "21E6".
(The sender asked to remain anonymous, and I am not sure about the copyright status of the file; so I would rather not repost it here yet. But it seems that several other people, including some of the 21inc competitors, have got a copy too; so anyone who is really interested can probably get it too.)
The slides don't have much new factual information, and basically confirm what we already guessed about the 21inc business plans. But they show that we severely underestimated their chutzpah and hype. Here are some random highlights (as far as I can decipher from the slides):
They had three relevant mining rig designs in the plans, that would require funding:
Codename Qty TH/s kW Cost Deploy Turnoff Profit($) --------------- ---- ---- --- ---- ------------ ----------- ----------- CyrusOne(v2), 7904 2.0 1.3 --- (already on) Apr 2015 ~23,000,000 IO(v1v3) 3250 5.2 1.3 2000 Jan 2015 Aug 2016 ~24,000,000 Brownfield(v3) 1900 5.5 1.3 2450 Mar 2015 > Nov 2017 ~20,000,000 
The "TH/s", "Cost", and "kW" columns are per "system", i.e. a mining unit containing many chips. The last column is the expected profit to be made from each set of mining hardware over its expected lifetime. (The slides have some other details that do not seem to be important.)
The first line is the hardware that they were mining with at the time of the presentation; that must be why the "Cost" (as far as investors are concerned) is given as zero.
The second line seems to be an upgrade of their previous mining hardware from v1 chips (which gave 2.7 PH/s total at the time) to v3 chips (which would give 17 PH/s) .
In reality, we have seen that their share of hashpower dwindled through all of 2015, and (AFAIK) they haven't mined a single block in the last six months. Were they still mining with CyrusOne on extra-life, or were they using the upgraded IO which was turned off prematurely? What happened to Brownfield?
However, their mining operations were secondary; the meat of their plan was the embedded chip, called BitSplit at the time.
The BitSPlit chip (as we suspected) was hard-wired to send 75% of the block reward to the 21inc wallet, whose address was burned in the silicon, and 25% to the user's wallet.
By my calculations, assuming 50 GH/s and no increase in the difficulty, the BitSplit would mine one block in 570 years, on average, and collect less than 2 BTC of reward in that time. So, of course, the chip was hard-wired to mine into a pool run by 21inc, that would spread the user's 25% of those 2 BTC (expected) into a daily regular trickle of a couple thousand satoshis. Their own mining operations would provide the BTC needed for the pool payouts of all the millions of chips that they expected to be running out there.
They projected to release 3 versions:
Model Qty GH/s W Cost Deploy Profit($) --------------- ---------- ---- -- ---- ------------ ------------ USB hub-charger 250,000 38 15 $35 Mar 2015 ~8,000,000 Embedded chip 1,000,000 63 15 $8 Aug 2015 ~103,000,000 BitSplit Inside 10,000,000 20 5 $0 Oct 2015 ~292,000,000 
The "Qty" is the expected number of units sold. The last column, IIUC, is the profit that 21inc expected to make from the 75% cut of the BTC produced by all the chips, over their expected lifetime.
In the above "USB hub-charger" model was a USB charging unit, roughly 3 x 2 x 1 inches, with 2 USB outputs and a mining chip inside, produced by 21inc themselves "to seed the market".
The second line, which I called "Embedded chip", seems to refer to discrete BitSplit chips provided by 21inc and included in consumer devices (like routers etc.) by OEM manufacturers.
The "BitSplit Inside" model would be the BitSplit integrated into the chipsets of other manufacturers, and manufactured by them. Its cost is listed as "$0" (for 21inc) because they expected those manufacturers to shoulder the cost of manufacturing and integrating the mining chip.
Apparently the market-seeding "USB hub-charger" was later replaced by the "Bitcoin Computer" (aka the PiTato). In one slide it is called "multifunctional BitSplit device", and depicted as a sleek shiny black box, the size of a cigarette pack, with a power cable and 2-3 USB or similar outputs. If that is supposed to be the PiTato, presumably they had not yet realized that a 15 w computer would need a cooling fan with a miniature wind tunnel on top.
In the last two entries, the manufacturers (not the device owners!) would be rewarded with the 25% slice of the BTC mined by those embedded chips. As an example, the slides say that a manufacturer who produced one quarter of the embedded BitSplits would get the 25% cut on the BTC yield of those chips, that was estimated to be between 2 and 4 million dollars per year of revenue in 2015--2018. Those numbers are based on the following predicted mean BTC prices: $350 for 2015, $1000 for 2016, $2200 for 2017, and $5500 for 2018.
So, their main business plan was fantastic: the OEM and chipset makers would pay the costs of producing and integrating the chips, the consumers would pay the cost of operating them, and 21inc would get 75% of all BTC mined by them, expected to be worth 400 million dollars.
It makes sense to invest 100 million in that plan, right?
EDIT1: Sentence order, typos.
EDIT2: See also this comment below about other sources of this info and this comment about a fatal flaw of the PiTato mining chip.

Repost - I hate my Fucking Mining rig! (Not really)(Long)

Wanted to write a short write up on my journey of Crypto mining for some of the newer people and people who want to get into it. Not trying to discourage anyone from starting, but want to show the progression of a newbie.
So I am a good with computers and learned of Bitcoin when it was about $7 a coin. Laughed at the idea of some computer doing some math and getting some BS currency. Million dollar mistake on my part, but hindsight is always 20/20.
Anyways, Learned about ethereum in May. Bought some at around $180 and bought all the way up to $330. Now to the mining rig. Ran all of the calculations and with a 180 hashrate and 900 watts I was gonna get 6-7 Eth per month. Shit was gonna be profitable in under 3 months. I was gonna be a fucking crypto allstar and be rich as fuck!
Bought all of my parts literally the day before they were nonexistent. Literally bought the last RX480's from Amazon. Here is a list of my parts.
Asrock board Pentium dual core processor 4 Gb of ram 128 gb SSD 1200 watt Rosewill PSU 6 Sata to Molex PCI Risers (Junk) 6 RX480's - 2 Asus Strix, 4 Gigabyte Total cost - Roughly $2,500 (Pennies compared to my future ROI)
Please keep in mind that I am not posting every single miner issue that I ran into such as fucking with Wattman for a few weeks before learning about Trixx and Afterburner.
I've built computers before, so that part wasn't hard. Set everything up and get windows 10 running.
Problem 1 - Computer doesn't see all of the cards. Had to run the drivers a few times and tweak some shit, but got all 6 cards seen.
Miner hurdle (See what I did there) but off to the races. Let's get this bitch running so I can begin planning my retirement.
Get Claymore running, Got Trixx to overclock. Ran my cards at -96, 1200, 2200 fans at 85% (Cause I'm cool like that.) Major stability issues from the start. 1 card (Asus) would crash all the time. Didn't know about the watch dog feature in claymore that would restart my rig when a card crashed. Great feature but my computer would go into this state of having power, but not loading the operating system. Even if it did restart, most of the time claymore would get stuck right before setting the dag's and would just lock up. (Claymore program is awesome by the way, this was my rigs fault)
Could not get this fucking Asus card to stop crashing, even on stock settings. Sent the bitch back RMA style. Asus said something was wrong and sent me a new one.
Awesome, lets get this bitch running. I need to start looking at sick houses in Costa Rica to move to once I am rich as Fuck!
New card makes things better for a few days. Not 100% stable but better. Go to vegas for a driving thing (Race cars - Future rich guy stuff) and this mechanical demon starts crashing every few hours. Luckily I had Google remote desktop installed so I could log on and restart it or change settings in Trixx. Had to have my GF unplug it and plug it in a few times.
Get back home, fuck with this thing but still random crashes on random cards. Decide it is the PCI risers. Contact seller who will send me some more for free. Slow boat from china took two weeks to get them. They arrive but still some of them are bad. Can't seem to piece together 6 good ones.
Did some research online (Ethereum Forum and Reddit) and decided to get some new style of risers V007 6 Pin to Sata ($70) and they take a month to get here. Plug them all in and they seem to be working much better. Decent stability, But I ain't got time for fucking stock bios. Let's ramp these bitches up and get 32 MHs per card at 600 watts from the wall!
Actually flashing the bios was pretty easy. Thank you 6 pound 9 ounce baby jesus! Long story short had some major stability issues and bounced around with some different timing straps before finding the right ones. (Uber 3.1 for Samsung memory)
So now that we've got some good hash speeds and decent stability let's ramp this private ATM up a little bit by dual mining some Decred. Get dual mining up and running. go to sleep. Wake up the next morning expecting to see myself on the top 100 forbes list. look at my mining rig stats on my phone and see that it died roughly and hour after I went to sleep. Walked toward my rig on the red carpet I had just installed and saw that it was off. Flicked on the light to check it out. No light, WTF? Well I'll be god damned, no power in this whole fucking room. Checked my breakers and sure enough this metal motherfucker tripped my breaker.
No worries though. I'm smart as fuck. I'll just undervolt the shit out of it to get the power down. No way in hell I am just mining ether. I'm going balls to the wall!
As you can expect I had many days of stability issues and tripped breakers. But fuck it, I have homeowners insurance. Burning it to the ground will be covered. (Didn't happen)
My surge protector must be maxed out. Let's buy a bigger one ($25). Same issues.
Fuck Decred, I'll mine SIA, less power. Damn I'm smart.
Rig is more stable with Sia and no tripped breakers. Family medical emergency, have to fly north for a few days. But my rig has been fairly stable and I've got remote desktop if anything goes wrong.
Arrive at airport, check mining stats, rig is down. No worries remote desktop. FUCK, not responsive, no way to remote into the rig and no way to remotely power it off and on.
Lost 4 days of mining. But no worries the difficulty is only, Holy shit that's high! But the price of Ether will make up for it. Ether crashed to the $200's. Oh well, maybe a 10 room house in Costa instead of a 12. No sweat.
Get back to my house and this whore of a machine is just sitting there in a computer coma. It's on but it's not. LED lights glaring at me like "Fuck you human, I ain't doing your stupid math problems!" Fuck you machine, I'm your master. You will do my math problems and you will fucking like it.
My AMD Drivers seem to disappear and the computer goes into a coma like state. Someone on Reddit suggested using the 16.9.2 drivers. Installed and they worked better.
Still random crashing. This shitty PSU must be maxed out. Fuck you PSU, I'm getting you a little brother (EVGA 750 gold $120.)
What do you mean you have to jerry rig a second PSU so it starts without being connected to a motherboard? 2 more hours of my life wasted.
But finally some stability. On my way to being fucking rich. I start looking at people in bentley's and can only laugh. You dumb fuck, I'm gonna be way richer then you. Gonna get a Bugatti for each day of the week.
Damn this difficulty is a bitch. Fuck you Genesis Mining and your pallets of GPU's. You're killing me smalls!
But anyway, on my way to rolling around in my fuck you money!
Fuck you dag file 135, you're killing my future millions. Fuck you dag 138, you dropped me to 167 mhs.
Thank god AMD was there to save my ass with their dope ass blockchain drivers.
download, run DDU, Restart, install drivers, restart, run pixel patch, restart. Perfect, I'm in the money now! I can taste the caviar and champagne already.
Now my cards only run 4 Mhs each. WTF? Try a bunch of the other new drivers. Same shit. Roll back to 16.9.2 and they run fine, just at 167 instead of 180.
Someone on a forum said he had the same issue and did a fresh install of windows 10 and it worked.
So I'll just reformat my SSD (Windows wouldn't do a fresh install within the operating system. Fuck you Bill Gates! Gonna buy you once I get this thing running at 180.)
Format SSD, plug back in, throw in my gangster ass boot USB drive. Ramdisk error. Fuck you Bill Gates! Reformat SSD multiple times, lots of forum reading. Install windows from another computer through command prompt (I'm a coder now as well.) This shit has got to work, I did it in command prompt bitches!
Same fucking error. Now down to an 8 bedroom house in Costa and only 6 Bugattis.
Let's try unplugging my 6 cards and see if that works. Thank you 6 pound 9 ounce baby jesus. Windows installed.
New drivers work and I'm back at 180! Raking in the cash now.
With those speeds my Asus cards crashed. Had to dial down the hashrate to 177.5 for them to be stable. So now going to use some commands in claymore to run the Asus cards at lower speeds while letting my other cards mine harder.
I wrote this to let people know that mining isn't all Bugatti's and caviar. These machines are fickle little cunts that do what they want. No system is the same. So when you post on a forum, people will give you advice on what may work. But what works for them, may not work on your rig. In the end it's up to you to figure it out.
I have spent countless hours after work and on weekends working on this bitch. Hell I've probably spent a few hours just staring at it and thinking about all of the ways I could destroy it slowly.
While I love Etheruem and do value the knowledge gained, I would have made more money just buying Eth and holding.
The guys you see on youtube building sick rigs with crazy specs have been at it for a while. They have worked through the process and know how to solve all of the problems. You have not and will have to work them out on your own.
My whore of a rig will pay for itself soon. But I would suggest that if you want to start building a new mining rig. Check the difficulty chart and make sure you have tons of free time to fuck with it.
I'd post my wallet address for donations since I just saved you $2,600. But I am afraid hackers will steal my monies :)
Hope you enjoyed my mining life story from the past few months.
Edit - Had an Asus card die on me and replaced it with a 1070ti. Nvidia is so much easier!
My rosewill 1200 watt PSU melted the 8 pin port and cable. Had to drop $300 on Amazons last 1300 EVGA.
But my rig has well surpassed it's cost and is still mining away like a champ. Eth for life!

A heads up to those wanting to use PCIe splitters/switches.

Well, after 129 miner restarts in SMOS I've finally gotten my 8 GPU rig mining stable for 16 hours straight. I'm using Supermicro boards in my operation to have IPMI and limit having to move rigs or monitors around to troubleshoot. Once the kinks are worked out its great! Anyways my board only has 7 PCIe slots so I've been experimenting with splitters to get me to 8 cards. Its been a long road. I started with a couple of those x1 into 4 USB cards which kinda worked if I was running less than 6 total GPUs and no more than 2 cards on each splitter. They are funky. I could run 4 on the board and 2 on the splitter for days but if I added 2 more to the board I had constant crashes. I spent an immense amount of time messing with the PCI gen, MCFG setting (base address for PCI devices) with mixed results. Finally as I gave up yesterday and put 2 cards back in another rig my x16 to 8 USB splitter finally arrived! I threw it in and hooked up 6 GPUs to it and I'll be damned it ran for 30 minutes no problem. I said screw it and grabbed 2 more cards again and had some rejected shares. Switched the slot back to PCI Gen2 and what do you know. Haven't had to reboot yet.
Obviously its known your mileage will vary using splitters like this. It won't magically make a 20 year old motherboard support more cards. But if you have a modern-ish board that doesn't have enough slots it may be the ticket. I know people have had luck with those 4 GPU splitters I'm still not sure why they were so unstable for me but hey this works. Only needing one x16 slot to run cards I may just opt for a dual CPU board and do some CPU mining as well if a new CPU only algorithm triumphs over Cryptonight.

[USA-CA] [H] Nearly-complete PC build (i5 CPU, 16GB RAM, MSI motherboard, Fractal Design case, Asus ROG Strix RX480 OC GPU) [W] Local cash, trade for Oculus Rift Touch

After some recent misadventures (I started out trying to upgrade this PC, but basically ended up building a new one by accident), I'd like to find a new home for my previous build.
As of right now, this rig is missing only a power supply and SSD or HDD (I migrated both items into my new rig), but is otherwise fine. This machine was built and used over the past couple years for light gaming and home-lab work, and the GPU was purchased new by me from Amazon and wasn't ever used for bitcoin mining or anything like that. I've found that it handles most modern games quite well at 1080p. Here are the specs of what I'm including:
Also, here's an album of timestamps.
I'm asking $350 (open to reasonable offers) local cash in the San Francisco Bay Area. I live in the East Bay and work in the South Bay, so I'm happy to meet up somewhere mutually convenient. I'm also open to trades for an Oculus Rift Touch setup, if anyone has one they're looking to trade. Let me know!

Romantic or not, who's someone who has truly changed your life for the better, or who you're just plain grateful to have around?

Wall of text incoming. May not be germane to the topic per se, but felt like writing it.
For me, it's my best friend who I originally met in sixth grade. I had been homeschooled up to that point and I was always a socially awkward kid with very fringe interests, and I got taken out of elementary in second grade because of bullying, so I was understandably reserved about starting middle school and reintegrating into the public school system. I still remember it, clear as day. It was my first day of sixth grade, and being myself I had shown up in full formal dress - button-down shirt, belt, tie, the works. (Don't ask.) After homeroom, I walked into my first class of the day, English, and sat where there didn't seem to be anyone else. Then he walks in, sits right next to me and starts a conversation, I think about video games. I mentioned some obscure game he didn't play (of course), but he played along and acted like he did and even BSed his way through a couple questions I ask him. We exchanged emails and before the end of the month we set up our first sleepover, and the rest just went. He was also an awkward kid who didn't have many friends - obviously not as bad as me, but it allowed us to establish a connection.
We had a ton in common from the get-go and it seems like we get more and more each day. He introduced me to Steam, convinced me to setup an account and talked my mom into allowing it, and got me into PC gaming; then I got into PC building and hardware, convinced his dad to let him build one and helped him build it, and then watched him build a second one completely independent of me about two years later. I taught him how to touch type and write well, and I'll still go back and incredulously read some of the stuff he would write one or two years back. He spurred me onto the idea of starting our own business when he was at my house one weekend, a business which has now grossed over $3k with us as pretty much the sole proprietors and employees. He got me into cryptocurrency back in early 2015 when Bitcoin was $300 and he had his own jerry rig of USB miners, a topic which I'm now very actively involved in and doing my science fair project on; we're also planning on divesting some of our business earnings into a legitimate mining venture. And so on, and so forth - anything he gets into, I get into, and vice versa ad infinitum. We have so many common interests and we know each other so well it's crazy.
Above all, he took me out of my shell. In the middle of eighth grade, he recalled that day we met in sixth, and said he noticed me sitting alone at the back of the class and decided he'd give me a chance. God fucking bless his soul, because I don't think there's been a single more pivotal point in my life. Talking, chilling, and doing stuff with him all the time gave me an actual practice base for social skills and convinced me that I was someone worth putting myself out there. I started sitting with the "cool kids" at lunch at one point, and now they all say I'm one of the best people they know and they're glad to talk and hang with me even though I don't necessarily align with their interests. I sent a Snap to everyone I felt grateful for this past Thanksgiving and nearly all of them had great positive stuff to say back. When I walked in the door for the first time at my day camp this summer, the whole room lit up, and everyone was glad to see me. It's fucking incredible how far I've actually come and I owe almost all of it to him and the chance he was willing to give me back then.
But most importantly, he's still the best friend I have, and I'm still the best friend he has. We still have more in common than any other two people I know, and likewise for how well we know each other. Every time I go over to his or he comes to mine I feel genuinely happy and glad to see him again, in a way that almost nothing else makes me feel. His mom died unexpectedly towards the end of eighth grade, and at the funeral I cried fucking uncontrollably because I truly do feel for him. We went on to different high schools, and we both have way more non-mutual friends now and do tons of things that aren't with each other, but our link is still the strongest of all. He lives on the nice side of town and I live in the ghetto, he's Jewish and I'm a Catholic-born agnostic, he doesn't give a shit about school and I have a 4.9 GPA, he's a die-hard Apple fanboy and I have an Android, and on and on - but none of that shit matters. We're friends, and we're great friends.
I felt compelled to write this because "Still the One" by Orleans came up in my playlist today and I noticed how many of the lyrics feel relevant to us, minus the romantic part. "Sometimes I never want to see you again...but I want you to know, after all these years, you're still the one I want whispering in my ear," "Changing, our love is going gold...even though we grow old, it grows new," etc. etc.
Thanks to anyone who read that. Who's someone like this in your life?

Lottery/Solo Mining

I have set up a small rig, with a few usb miners that i managed to get for a cheap price, was reading about on forums and read about setting up your own node and mine on your own, in hope to mine a whole block. I have set up everything, switched on cgminer and passed on a few parameters... -o -u -p and --btc-address. Now my question is, for the --btc-address parameter, i need to insert my receiving bitcoin address ? can i use one from my hardware wallet or does it have to be one that the Bitcoin-QT (Bitcoin Core) that cgminer is attached to ?

How to get started on GPU mining on Pizza Pool (gpu.pizza) [Nvidia/linux/ClosedSource]

Sunday morining the 0xBitcoin Discord got a surprise from @0xPiZzA...
hi guys. i am 0x778, again! has it gone a long time and you miss me? 8^D= i wait two more weeks since last time, want to check you to see if you are ready for gpu and 0xBITCOIN. today i am ready to release Closed Source GPU Miner for everyone, works for my new Mining Pool name " PiZzA Pool " ! \o/ new pizzaminer is ALPHA software : means speed good but has bugs. Linux only OS. new pool PiZzA Pool also ALPHA but in testing now, available for your to try. credit system is counting. automatic payment, i am building it now. XD lets GO for best! i am not support Help with this software, please figure it out. i believe you can do it. PiZzA Pool going to donate 2% to 0xBITCOIN project / Infernal Toast who will make Open Source Gpu Miner in competition with pizzaminer and Prevail in Triumph. .o/\o/ when you ready, more info : http://gpu.pizza/ :heart: Have Fun, Love 0xBITCOIN 8^D= ~~ 0xPiZzA :heart: 
GPU mining!!!
PiZzA pool - http://gpu.pizza/
Before we start...
THIS SOFTWARE IS CLOSED SOURCE
I DON'T OFFER ANY WARRANTIES ON THIS MINING SOFTWARE
USE AT YOUR OWN RISK
Yet the miner works and I've been paid by the pool (71.17318134 0xBTC):
https://etherscan.io/address/0x79c5BE8f4098208006C7940cF72dAE71738b39b6#tokentxns
1. Prepare your mining rig
Download required programs:
http://gpu.pizza/#download
https://www.ubuntu.com/download/desktop
https://rufus.akeo.ie/
Using this software is risky, but you can minimize the risk by planning. Ideally you want a sanitized GPU mining rig.
This means:
  • No private key!!!
  • No saved passwords!!!
  • No files you are not comfortable with losing!!!
Use this as a basic security audit if you have an existing GPU mining rig.
2. Download and Install Ubuntu
You can Google this.
I believe in you, you will figure it out. :-D
But get an .iso and use Rufus to make a bootable USB.
3. Install Nvidia Drivers
Don't download them from the Nvidia website. Use repositories instead. This guide worked for me: http://www.linuxandubuntu.com/home/how-to-install-latest-nvidia-drivers-in-linux
Make sure you are connected to wifi at this stage. The error message will not clue you into the fact that your internet is not working.
4. Run the pizzaminer software
Details are in the README.TXT. But essentially all you need to do is run the program. Make sure in properties it has permissions to exectute. Also run each miner in their own terminal instance.
http://gpu.pizza/download/pizzaminer-v0.0.1-alpha/README.txt
CUDA_VISIBLE_DEVICES=0 ./pizzaminer 0x0123AbC... CUDA_VISIBLE_DEVICES=1 ./pizzaminer 0x0123AbC... CUDA_VISIBLE_DEVICES=2 ./pizzaminer 0x0123AbC... CUDA_VISIBLE_DEVICES=3 ./pizzaminer 0x0123AbC... 
5. Configure Autostart
Inside the directory where pizza miner is create a file (autostart) that is executable and contains your payment address:
#!/bin/sh xterm -e -hold CUDA_VISIBLE_DEVICES=0 ./pizzaminer 0x0123AbC... & xterm -e -hold CUDA_VISIBLE_DEVICES=1 ./pizzaminer 0x0123AbC... & xterm -e -hold CUDA_VISIBLE_DEVICES=2 ./pizzaminer 0x0123AbC... & xterm -e -hold CUDA_VISIBLE_DEVICES=3 ./pizzaminer 0x0123AbC... & ... 
Then from Start>Startup Applications add the following task:
Name: Autostart pizzaminer Command: autostart (browse for file created above)
7. Optimization
v0.0.3 CPU optimization
Before the CPU was bottle necking the GPU utilization in certain cases. v0.0.3 fixes this and it's stable for me. With multiple cards on a Celeron G39XX you can expect a 50%+ boost in overall hash rate.
Overclocking (EXPERIMENTAL!!!)
This command should allow basic overclocking, monitor free initialization. Honestly haven't had much success in the overclocking department. Let me know if you do!
sudo nvidia-xconfig -enable-all-gpus -cool-bits=28 --allow-empty-initial-configuration 
6. Known Hashrates
GPU MH/s MH/s MH/s
Version v0.0.1 v0.0.2 v0.0.3
GTX 970 (40 MH/s) (55 MH/s) (75 MH/s)
GTX 1050 Ti (40 MH/s) (75 MH/s) (90 MH/s)
GTX 1060 (60-70** MH/s) (100 MH/s) (150 MH/s)
GTX 1070 Ti (90** MH/s) () ()
GTX 1080 Ti (140** MH/s) () (325** MH/s)
**unconfirmed
Please tell me your hashrates to add to this table!!!
If this guide has been helpful please consider donating:

What is the amateur friendly way to get into mining?

I want to do some mining, as a hobby, with no focus on profitability, but learning about computers and crypto will be a reward in itself.
Right now, I have an old laptop I have mining at a very low rate, which is fun but I want to get a little more serious.
It seems I have a few options. I could assemble a mining rig with multiple GPUs, while keeping the budget around 1000 bucks (lil more probably). I worry about the cost of this approach, but it would also yield the most experience.
The other options seem to be buying specific mining hardware like an ASIC miner (seems very expensive) or I saw USB miners like the mooonlander2 which seemed good for a hobbyist (like myself) but they are too plug & play, so I would learn less.
Yall have any suggestions? I know this is a very pricey time for components, and I also dont wanna spend money and have my miner become obsolete too quickly. I've been lurking and reading the sidebars of various mining subreddits, but I'm still struggling to decide on an approach.
I don't much care about which coins I mine. Probably not bitcoin, since that seems too hard for the hobbyist. (though perhaps Im mistaken)
