Then, follow a step-by-step guide on how to assemble everything into a plastic milk crate to facilitate airflow and cooling.

Part 2: Linux Setup

Part 2: Linux Setup

Follow a detailed set of instructions that will have you up and running with Linux on your litecoin mining rig in about an hour.

The guide is tailored to the complete Linux beginner and includes every single command that you’ll need to input—no guesswork or incomplete steps!

Part 3: Windows Setup

Part 3: Windows Setup

If Windows is more to your liking, we’ve got a guide for you, too. Covers a complete installation from start to finish: BIOS settings, drivers, mining software, auto-startup, remote admin, and more.

For more advanced users, undervolting your GPUs (to save power) is also included as an optional step in the guide.

Part 4: Optimization

Part 4: Optimization

After you’ve got your litecoin mining rig running, check out the optimization guide for tips on getting the best performance possible from your GPUs via overclocking and cgminer tweaks.

    Hey bro, I’ve been mining for about a month with great success. I now have some crazy problems. I build another rig, getting massively insane hardware issues. On my first rig the engine and memory speed is locked and I cannot change it. Does anybody have any clue as to what is going on. I’ve changed bat files, re-installed drivers, blah blah done everything in every forum on crypto on google. No results just fail.

    • Will says:

      Try plugging your monitor in to the GPU that is reading the lower clocks. If you are running certain GPU’s such as the hd series you’ll probably need to create dummy plugs for the vga outputs on your GPU’s.

    Hi everyone,

    has ever someone of you experienced repeated breakdown of the motherboard ASRock970 Extreme4 – I used the same rig as described in your guide with 3x Sapphire 7950 and a Corsair/Seasonic 860 W PSU. 5 out of 8 boards crashed independently after a coupe of days and do not power on again. The PSU is working with another board – so it’s not the PSU. any ideas???

    • ezpacer says:

      Velniukas, my first suspicion is that your supplier is peddling damaged boards, possibly from improper storage conditions. At any rate, my asrock 970 ex4 has been working without problems for 8 months. Good luck in finding your solutions!

    • Edwardf says:

      The RSRock 970EX4 mobo has a CLEAR CMOS botton on the front next to the USB ports and also a RESET button next to the power on button on the rear of the board. There is an explanation of the use of these buttons on page 27 & 30 of the manual that comes with the mobo. I have used these to solve problems with power on and blank screens, etc. with my two rigs from time to time. I do not know exactly why but they seem to work to cure problems when nothing else works. It is very unusual to have that many defective moboards. I have read that some people have forgot to connect the 12v cpu 8 pin power cord to the mobo also which would cause the mobo to appear dead.

      • velniukas says:

        Hi Ezpacer, Hi Edwardf,

        thanks for answering – the clear cmos button or resetting it by shortcutting the Pins as described in the manual didn’t work. I have two boards that are running really fine in the same configuration >2 month(however only with Seasonic PSUs). I think, the corsair AX860 PSU gets a little too hot at 800 Watt at the wall. I had the PSU first in the crate directly next to the board. For the remaining rig I now put the PSU out of the crate to further ease heat dissipation. I think it was bad boards and thermal load in combination – however normally this should not have happened.


  8. Max says:

    I build the rig following the guide with 3 Sapphire hd7950 about 2 months ago and it has been running 24/7 ever since. I few days ago I’ve had a couple of power problems which I though was due to S/W or USB stick. But yesterday the mobo would not start properly so I inspected the rig and found PSU cable partially melted in ATX Power Connector (connector 9,10,11 with 10 particularly black). I have cleaned up the connectors, and the rig is up and running again but would like to know if anyone has experienced this. Should I use powered raisers to lower power flow through mobo connector? I would like to avoid having to buy a new one in the very near future.

    Awesome guide! I used this one and the one at to help me get my rig up and running. I used 5 sapphire 270 gpus for a 2.2 mh/s rate

  10. Johndoe says:

    I have two rigs on Xbuntu 12.10 each with two Sapphire 7950. Please see below the specs. Interestingly, I get only around 250-300 Kh/s for each card.

    Rig 1
    AsRock 970 E4
    Seasonic Platinum 860
    2 x Sapphire 7950 (SKU: 11196-19-20G)

    Rig 2
    MSI 970A-G43 AM3
    Rosewill CAPSTONE-1000-M Continuous 1000W
    2 Sapphire 7950 (SKU: 21196-00-20G)

    I followed Crytobadger instructions word by word. would like to know if anyone faced the same issues. Any help would be greatly appreciated.

    FWIW I want to assert some appreciation for this site. Kudos to the author for the appearance of clean organization and the presentation of what appears to a newb as credible information. Kudos to the community for what also appears to a newb as the relaying of credible information. Acts of selflessness; you all should be proud.

    Thank you all!

    Furthermore, I have some questions. I am not a newb in regards to IS in general, but I am a newb in respect to systems built for the sole puropse of mining. I’ve casually researched the topic only on a handful of occasions over the past few months, but I have recently began looking to build a rig.

    Perhaps some of you will be so kind as to shed some light about the current state of GPUs in the way of their prices and their availability? I seem to have came in at a time when GPUs are twice the price that they were roughly 6 months ago. Can any of you enlighten me as to what is coming down the pipe for the nearish future? Are there well-founded expectations for a new generation of GPUs with a lower price tag? If anyone here has good intel on this topic I’d love to be witness to it.

    Moving along, can any of you offer a predictable rate of change for the difficulty factor in mining litecoins? I’ve seen and attempted to read some charts but I have not knowingly found a reliable calculation or black-and-white percentage for difficulty change. I am plainly wondering if a box that I build for Y dollars will be able to pay for itself (and a second rig?) if it performs X kH/s. If said rig pays for itself, (considering that the value of litecoins remains flat, for example) when should I expect the payoff to occur? Again, I am looking for a change in difficulty calculation if such a thing exists.

    tl,dr – With the current prices of rig HW and value of LTC, will a newly built rig with 2 7950s pay for itself before being squashed by the growing rate of difficulty? Can the rate of change of difficulty be measured? If so, how do I do so?

    Pardon moi if my newbishness is overwhelming…

    Does any know if graphic card companies honor warranties even if the card was used for mining?

  16. BigW says:

    I returned a card to XFX that failed within the first few days. I had not overclocked it so it likely would have failed even if I was using it for something other than mining. Anyway, I don’t really think it’s any of the graphics card companies’ business what I do with my card whether it be play games, watch porn or mine with it. They sell it for my use whatever that may be. On top of that, they are making a ton of money selling graphics cards for mining. They should be happy with the increase in business and with that comes an increase in warranty claims.

  17. delsol7 says:

    Has anyone got this message on cgminer?

    Error -6: Creating Command Queue.
    Failed to reinit GPU thread 2

    I have no clue how to resolve this…. I am at normal setting on GPUs. Barely any overclocking and TC is also in 8000s. (I don’t remember exact number.) I goggled and saw someone saying something about TC being high but this particular rig has been running over 2 month without problem. Out of no where this error shows up and graphic card shows as DEAD on cgminer. Yet, if i plug in monitor, it displays fine. hum……

  18. I think it would be nice to build a hybrid system or farm with both GPUs for Script mining and Bitcoin Mining. Checkout the latest pci-e bitcoin mining card technology from CoinTerra .

    You can drop these in a rig just like a GPU.

    So if i went for a mining rig with 5 x radeon R9 290’s that i will leave 24/7 to mine.
    is it still worth it in this economy? or have i missed my chance?

    what do you guys think?

    serious breakdown of HD7950 Sapphire Grafic cards:

    Hi everyone – a while ago I reported in this forum a strong breakdown of ASROCK Extreme4 Motherboards – however I was mistaken – instead I have a significant breakdown of my grafic cards. I use Sapphire HD7950 OC Boost cards with the rig of cryptobadger. After some days/weeks the cards break down in the form, that they are shortcut so the psu power supply breaks down. changing the broken card in the rig and everthing works fine again. Temp not beyond 74C, GPU-Clock: 1025 – 1050 MHz, Mem: 1250 MHz, Volt: 1.084 -1.125V – Power consumpton of the rig: 750 – 820 W, PSU: Corsair AX860W so everthing in the right range – but 7 out of 28 GPU-Cards are already down!!!
    Any idea where the heck to problem lies?

    • CryptoBadger says:

      Wow, that’s some bad luck.

      Are the rigs plugged into any kind of surge protector/battery backup/power conditioner? Make sure that you’re using a quality surge protector at the very least. If your power isn’t that reliable, consider a UPS.

      Did you buy all of the GPUs at once? Unfortunately it’s possible that you were unlucky and received a bad batch. For example, I’ve used several dozens of MSI 7950 cards and I’ve only had to RMA 7 of them. All 7 that went bad were purchased in the same batch (I bought 9 cards total, so nearly all of them died), all within the first 6 weeks. Luckily the warranty on GPUs is generally very good, so while dealing with the RMA process is a minor hassle, hopefully you’ll have much better luck with the replacements.

      • velniukas says:

        Hi cryptobadger,

        thanks for your comment – unfortunately it seems to be a systematic problem. I’m living in Stuttgart, Germany and I assume, that the power is here around very reliable. – I experience the same problem also in France where I have a small bureau to save on my electricity bill. (9 ct per kWh instead of 28 ct (euro, not dollar)).
        It is always the first GPU and it always happens, when there is a small cold breeze, eg. window opens, door opens, ventilation to the outside starts, etc…
        I’m now trying to run the rigs only with 2 GPUs to see, if it is related to the PSU load. So far, all cards where from one supplier – however exept 3 cards I bought all from this supplier in one row. With one HD7970 I also have a breakdown (after 3 months) but the error is different.

        As long as I dond’t find the problem, I haven’t got a stable system… and with this Litecoin-prices and electricity bills I’m far of profitability.

    Does anyone have experience with the H81S2 motherboard? No one seems to be using it yet, but it might be a more cost effective alternative to the H81 Pro BTC. Specs here

  23. Jess says:

    Copied batch file to start folder but doesnt start cgminer upon computer restart. Any ideas on how to resove this issue?

  24. Walt says:

    I am using a ASUS HD7970 DirectCU II GPU. Do I still need to install the Catalyst drivers and SDK for this card and if so – would you please advise which version or link me to it?
    Thank you and regards

  25. Chuck says:

    Thanks for this guide! very useful! I have one request, could you add on “How to install scryptN miner” along side cgminer? My GPU rig cant compete with the asics so I want to switch over to VertCoin, SpainCoin, etc…
