Build your own Ethereum Mining Rig, part 1: Hardware

Ethereum GPU mining rig testbed.

My open-frame GPU testbed, mining Ethereum on a couple Radeon RX 470 video cards.

It’s finally time for an update to my popular 2013 Litecoin mining guide! It’s four years later, and Ethereum mining is where it’s at for GPU miners, so that’s what I’ve focused on. I’ve kept the same format and detail level as my old guide, so if you were around back then, you’ll know what to expect.

If you’re new to the world of crytocurrency mining, this guide should give even an absolute beginner all of the knowledge needed to put together an efficient Ethereum (or other GPU-minable altcoin) mining rig using readily-available consumer hardware.

This guide will be broken into several parts, each focusing on a different aspect of building your first mining rig. First, let’s take a look at what you’ll need in terms of hardware to put a respectable Ethereum miner together.

Build your own Ethereum Mining Rig, part 1:  Hardware

Here is the list of hardware that I recommend. Don’t worry if you’re not able to get exactly what’s on this list, I provide some excellent alternatives below the table.

Motherboard 1 x ASRock H97 Anniversary $90
Processor 1 x Intel Celeron G1840 CPU $45
Memory 1 x 4GB DDR3 DIMM $20
Power Supply 1 x 1200w Seasonic Platinum $260
GPUs 3-6 x Radeon RX 470 video cards (*see below) ~$180 each
Boot Device 1 x 60GB SSD -or- USB stick (Linux) $5 – $35
Case 1 x build your own* -or- open frame case $35 – $200

Some explanations and alternatives for each item:

Motherboard

Generally, any motherboard with PCIe slots on it is suitable for mining—typically one GPU per PCIe slot. The PCIe slots don’t need to be full-length, as we can attach GPUs to 1x slots with the help of risers. With that said, there are potentially some limitations when you start to pack a large number (4+) of GPUs onto one motherboard, even if that board has enough PCIe slots to physically accommodate them. That’s why picking a suitable motherboard is probably your biggest hardware headache if you want to run as many GPUs as possible in your rig.

Enter ASRock: they’ve released a couple motherboards specifically targeted at miners, and these should be considered the gold standard for 5-6 GPU setups: the ASRock H97 Anniversary and the ASRock H81 Pro BTC. If you can get your hands on either of these, they’ll work out of the box with 6 GPUs. I give a slight preference to the H97 because the 16x PCIe slot doesn’t block the adjacent 1x PCIe slot (so you only need five risers instead of six). However, these boards are often sold out everywhere—you may be able to get one from a seller on the Amazon marketplace or eBay, but you’ll likely pay a premium (both boards retail for under $100, but boards on the secondary market often go for more than that).

Biostar also recently released a board aimed at miners: the TB250-BTC. This Biostar board will work with up to 6 GPUs right out of the box, but it’s based on the newer LGA1151 socket and requires DDR4 RAM, which makes it a slightly more expensive option overall compared to the other motherboards I’ve listed here. If you opt for the TB250-BTC, make sure that you get a LGA1151 Celeron CPU and DDR4 RAM instead of the CPU/memory options that I linked in the table above.

If you’re not able to get one of the above, then the Gigabyte GA-Z97X-Gaming is a fine choice for up to 6 GPUs, but it may require a bit of BIOS fiddling before it recognizes all cards. It retails for more (~$160), but it should be available (note that there are several versions of the GA-Z97X-Gaming, if the one I linked is out of stock, try this link to search for others—just make sure whatever board you pick has 6 PCIe slots!).

If you only want to use 3-4 GPUs in your rig, then you’ll have a much easier time. Most boards with up to four PCIe slots should accommodate a GPU in each. Keep in mind that you can use old hardware that you have sitting around—the board doesn’t have to be recent. I dug out an old ASRock 970 Extreme4 that I used four years ago for litecoin mining, and it still works fine today for up to 4 GPUs (5 is possible with some work). So it’s possible to pick up an ancient board on eBay/Craigslist for nearly nothing and mine with less than 6 video cards.

CPU / Processor

This one is easy: buy the cheapest CPU that works with whatever motherboard you pick. When it comes to mining, the GPUs do all the work. Your CPU will essentially sit idle, so there is no reason to waste money on anything other than the bare minimum.

All of the motherboards that I recommended based on Intel’s LGA 1150 socket, so that means the Celeron G1840 is the current best choice.

If you go with an AMD motherboard, a Sempron CPU will do nicely.

Memory

4GB is fine. Overkill really, at least for Linux. If you have an old 2GB stick (or even 1GB!) sitting around and plan to run Linux, you’re good to go. If you want to run Windows, then 4GB is probably a realistic minimum.

While Ethereum mining is pretty memory-intensive, everything happens on the GPUs. System memory will be pretty much unused, so there is no reason to spend money here.

PSU / Power Supply

The power supply is extremely important—don’t skimp on it! A good, efficient PSU will keep your electricity costs to a minimum and more than pay for itself over the long run. I’m a huge fan of Seasonic and have built dozens of rigs with their PSUs. I’ve never had one fail on me, and they are some of the most efficient units around. The 1200W unit that I’ve linked may seem like overkill, but power supplies are most efficient when they’re not running near their rated maximum load. A 6 GPU rig will draw about 750 watts (assuming 6x RX 470 cards, properly optimized), which means a 1200W PSU will have sufficient headroom to perform efficiently.

If you’re planning on running only 3-4 GPUs, you can save a bit of money and go for their 860 watt model instead.

As far as alternatives, Corsair and EVGA both also make extremely efficient, highly-regarded platinum 1200w PSUs.

GPUs / Video Cards

Edit 6/8/2017: The AMD RX 470/480/570/580 cards are sold out essentially everywhere due to tremendous demand from miners. If you’re building a mining rig today and can’t get your hands on a RX 570/580 card, consider the nVidia GTX 1070. The GTX 1070 delivers roughly the same ETH mining performance as a RX 570/580, and it’s still available to buy (albeit at a higher retail price than the RX 570/580). The GTX 1060 is a less-expensive option, although it’s about 20% slower than a RX 570 when mining ETH. The GTX 1080 delivers roughly the same same mining performance as a GTX 1070, but costs more. If you opt for any of these nVidia GPUs, do remember to substitute the nVidia video drivers for the AMD ones that I link in the Linux/Windows portions of my guide!

The top Ethereum mining choice is currently the Radeon RX 470 / RX 480 line. The RX 470 delivers nearly the same performance as the RX 480 (within 4-7% or so) for a bit less power consumption—they’re essentially equal from an efficiency standpoint. The RX 470 is usually significantly cheaper than the 480, so generally the 470 is the best choice.

Which model to pick, though? While literally any RX 470/480 card will do, the most important thing to look for is memory speed if you want the best performance. Cards with a higher memory clock speed will generally perform a bit better while mining ETH (and can generally be overclocked more). Memory capacity isn’t really important beyond 4GB, so all other things being equal, there is no reason to shell out extra cash for the 8GB version of a card. It’s true that every GPU needs to be able to hold Ethereum’s DAG file in memory, and that file is slowly increasing in size—but it won’t surpass 4GB until late 2019 (and ETH’s switch to PoS will likely occur before then, anyway).

With all of that said, the 8GB versions of the cards tend to have faster-clocked memory than most of the 4GB cards, so if the price difference isn’t too large, spring for whatever is the fastest. Most of the cards fall between 1650 Mhz (6600 Mbps effective) to 2000 Mhz (8000 Mbps effective). The slower 1650 Mhz memory GPUs will hash at 21-23 Mh/s, and the fastest 2000 Mhz ones will do 25-28 Mh/s (both can potentially be pushed higher with BIOS mods and good luck).

Top RX 470 pick is the 8GB Sapphire Nitro (2000 Mhz memory); I’m not aware of any other 470 cards clocked that high. Any of the 4GB cards are fine budget choices if you can score a deal, but they’ll likely be clocked at 1650 or 1750 Mhz. MSI, Gigabyte, XFX, and Asus are all reputable brands—generally just get what’s cheapest if you’re going for a 4GB RX 470 build.

Top RX 480 choices are the 8GB MSI Gaming X, 8GB Sapphire Nitro, and the 8GB XFX GTR XXX edition. Most of the 8GB RX 480 cards are clocked at 2000 Mhz, so generally it’s just about price and the fan/cooler design. I generally wouldn’t recommend a 4GB RX 480 unless you get a deal, as they all seem to be clocked at 1750 Mhz or lower (including oddly, Sapphire’s 4GB 480 Nitro card), so you might as well just save some cash and get a 470.

Boot Device

If you plan to run Linux, you can use pretty much anything, including a ~$5 16GB USB stick (we’ll be using Claymore miner, which doesn’t write Ethereum’s DAG file to disk, so we don’t need to worry about wearing a USB stick out due to constantly writing to it, like with the stock ethminer). With that said, SSDs are pretty cheap nowadays and it might be nice to have one in case you want to try Windows at some point.

If you plan to run Windows, then a cheap 60GB+ SSD is your best bet. If you have an old mechanical hard drive laying around, that’ll work fine too.

The Case

I highly recommend against trying to cram a bunch of GPUs into a conventional PC case. You have two realistic options here: buy a purpose-built mining frame, or build something yourself.

The first option is straightforward, if not a bit more expensive. Here is an example of an open-air frame that will accommodate up to 6 GPUs, risers included. Here’s another option. You’ll pay a premium going this route, but it’ll save you some time and effort.

The second option is much cheaper, and (arguably) more fun! If you’re handy, you can put together a simple aluminium frame yourself for a fraction of the cost of buying one. If you don’t have the necessary skills or tools for that, I popularized building mining rigs inside plastic crates back in 2013, and that still works fine today (for up to 4 GPUs or so, anyway). At the bottom of this post, you’ll find instructions on how to build a plastic crate “case”.

Risers & Miscellaneous Stuff

If you’re building your own case (whether it’s from a plastic crate, or aluminium, or something else), you’ll need risers to connect your GPUs to your motherboard. If you’re buying a mining frame, most include risers. Risers tend to be pretty misunderstood among new miners, so here is what you need to know:

  1. Risers can be powered or unpowered. A riser is unpowered if it simply connects a GPU to a motherboard PCIe slot. A riser is powered if it additionally accepts power from the PSU (generally via a molex-type connector). Unpowered risers allow GPUs to receive up to 75 watts of power through the motherboard’s PCIe bus, just as if they were plugged in directly. Powered risers will take that additional power directly from the PSU instead, bypassing the motherboard.
  2. You may mix unpowered and powered risers, but the total number of unpowered risers should not exceed two (this includes GPUs plugged directly into the motherboard)! Motherboards are generally not designed to deliver more than 150 watts of total power through the PCIe bus, so two GPUs on unpowered risers is the safe maximum (2 x 75 watts).
  3. The newer USB-style powered risers often include SATA-to-molex power adapters. Throw these adapters away! SATA plugs are not designed to deliver 75 watts safely, and these can get hot enough to potentially be a fire risk (admittedly, 99% of the time you’ll be fine, but it’s not worth the risk). Instead, connect the molex plugs on the riser directly to your PSU (no more than two risers per PSU plug).
The different PCIe riser types.

PCIe risers: click to enlarge.

I do think the newer USB-style risers are the way to go—they’re longer and easier to work with than the old ribbon-style cables. Just don’t use the included SATA adapters! I bought a 6-pack of these and didn’t get any bad ones, but it’s always smart to buy an extra or two, as defects are relatively common. If you have older ribbon-type risers laying around, or can get them cheaply, they’ll work just fine.

If you’re building or buying a large frame, you might need extenders for some of your molex plugs and PCIe power plugs.

You’ll also need a power button, unless your motherboard has one built in (which is fairly rare). This will do the trick, or you can build one into your plastic crate if you plan to go that route (see below).

Some people have reported that their rigs won’t boot unless they have a monitor connected, although this seems to be fairly rare (my own rig boots fine without a display attached). If this happens to you, you’ll need a dummy plug.

Building your Mining Rig “Case” from plastic milk crates

(I’ve copied the instructions from my original 2013 guide here and updated them slightly.)

Here is what you’ll need to create a simple DIY plastic crate housing for your miner:

Plastic milk crate (can stack two and put your PSU in the lower one) $10 each
Plastic stand-offs $3
6 x #4 3/8″ wood or metal screws $1
Brace to rest GPUs on (1″ PVC pipe works great!) $2
a few cable ties (8″ or so) $2
power switch & LED (optional) $5

You can get plastic crates in most home improvement stores if you don’t want to ship it from Amazon (it’ll be cheaper, too!). I picked mine up at Lowe’s for under $5 each. You should be able to get everything else on the list at Lowe’s if you happen to have one near you, too. As far as tools go, you’ll need a drill and a knife capable of cutting into whatever plastic crate you buy.

 Assembly Steps:

First, attach your CPU & heatsink/fan to your motherboard, and place your RAM into the memory slot(s). Then follow the general steps below to mount everything into your plastic crate.

Click the images for a close-up look at each step.

  1. Step 1Place plastic standoffs on the bottom of your plastic crate, and rest your motherboard on top of them. Make sure that all of the essential ports are accessible (SATA, USB, keyboard, mouse, etc). Use your knife to cut away pieces of the crate if necessary so that all ports you plan to use are exposed. Then plug your riser cables into the PCI-E slots of your motherboard.
  2. Step 2Place your brace (1″ PVC pipe is really ideal and won’t flex over time) so that it is sitting above the motherboard, high enough for your GPUs to rest on. Cut the brace so that an inch or two sticks out on either end of the crate.
  3. Step 3Drill holes in your brace so that you can secure it with cable ties (see image). Do not simply rest the brace on the crate! An accidental bump can cause it to fall into the crate, along with ~$1000 worth of GPUs if you do that!
  4. Step 4Connect each GPU to it’s corresponding riser cable, resting the bracket end on the lip of the crate and the other end on your brace.
  5. Step 5Screw each GPU down into the lip of the crate. If you drill small pilot holes ahead of time (mark where to drill with a sharpie), this is much easier.
  6. Step 6If you have a power switch and LED, mount them into one of the crate’s corners. I was pretty sloppy with mine, but it’s functional.

 

You’re done! Simply connect everything to your power supply and you should be ready to power your rig on for the first time. If you have a second crate, you can put your power supply in there (along with your harddrive if you’re using Windows), and stack it under your main crate to save some space.

In the next part of this guide, I’ll show you everything you need to do to start mining under Linux (or skip to the Windows section if that’s more your thing)!

    Hi,

    It’s hard to find one of the graphics card mentioned in the thread. What are you thoughts on the MSI Gaming GeForce GTX 1070 8GB GDDR5 SLI DirectX 12 VR Ready Graphics Card (GTX 1070 GAMING X 8G)?

  2. Ben says:

    Since they are more expensive, will this system work with a single nvidia GTX 1070? Is there a difference between having 3 less powerful GPUs vs having one more powerful GPU? Thanks!

    • CryptoBadger says:

      The GTX 1070 will work fine (either a single card, or multiple). The GTX 1070 is about the same speed as the RX 570/580 for ETH mining. Buy whichever is cheaper for you (currently, the RX 570/580 is sold out everywhere, so the 1070 is probably your best bet).

  3. Adrian says:

    CryptoBadger, thanks for this very useful guide. Do you think that at this point 1070 would be a safer bet then rx460/470?
    Also what do you think about using multiple smaller psu’s for a beginner rig?

    • CryptoBadger says:

      Yes, the GTX 1070 is a fine alternative, given that the AMD cards are out of stock everywhere.

      I don’t really recommend multiple PSUs, especially for a beginner, due to the risk of hardware damage if wired incorrectly. A single high-wattage PSU is safer, and probably less expensive.

  4. Tuborgz says:

    Can’t find any GPU at decent price besides Radeon 560. What will be the performance difference to the 570? Thanks

  5. petersweden says:

    Will this GPU work fine with my setup?

    ASUS Radeon RX 560 4GB ROG Strix
    Grafikkort, PCI-Express 3.0, GDDR5, 1285/1275MHz, Polaris.

    regards Peter

    • CryptoBadger says:

      The RX 560 will work, but you’ll have disappointing hashrates compared to the RX 570/580. I believe the 560 gets about 12 MH/s (eg: the RX 570 is about 250% faster).

      • Johnny says:

        Dear crypto guy, what do you think about this:

        I have an old hd7870, and I can buy three more for around 50$ a piece. I have an asrock970 pro3 r2.0 motherboard with a fx4170 and 8gb of ram. Also i have a 60gb ocz ssd.
        Could it be an efficient mining rig, and what psu should I buy? I dont need this pc any more, cuz I have notebook and this is just sitting around. And the most important part, I dont have to pay for electricity cuz I live in a dorm and I just pay for rent.
        So would it be profitalbe?
        4x hd7870 sapphire dualx cooler for 150$ and a good psu for around 120-150$
        My investment is around 300$, and no electricity bills!

        I cant buy any new gpus cuz they are overpriced or sold out.
        Thanks man 🙂

    Nice article. How long mining on Gpu will work?

    • Ben Millar says:

      The interest in mining doesn’t seem to be slowing down, the global shortage of mother boards and GPu’s seem to suggest it’ll be going for a long time. Plenty of people building rigs..as am I.

    So i want to build a rig, ive found all the parts apart from the gpu, i cant decide between rx570s, 1070s, 1060s.
    I can get rx570 sapphire nitro+ 8gbs on amazon for 200£ but i saw somewhere that they wont be released until September? Any other options?
    Im too worried about the dag file size hashrate reduction by then so thats why I looked into nvidia cards.
    I thought about buying 1070s but i dont know which is the best one and theyre quite expensive

    I wont be able to build my rig until mid August since im going on holiday, but i want to get it finished before September.

    I need a second opinion about which card i should choose, which coin i should mine, and if i should even bother with ethereum at this point and maybe go zcash instead. (with nvidia)

      Check to see if power supply is issue. Do the psu “paperclip” test and see if it stays on or not. Then you’ll know if it’s the psu.

    Whats about the ASUS STRIX R9 390X?
    I’ve got one in my rig and will buy another one 🙂
    good idea or not?

    I have 10 powered risers all appear to be duds.

    I’ve bought new USB 3 cables for testing.

    Mixed and matched 1xusb adapter’s to different 16xrisers, tried various combinations of gfx card configurations 1 in pcie16x, 1 via riser, All via risers etc.

    1000w platinum psu.

    Tried 3 different motherboards, latest bios, oldest bios and bios somewhere inbetween.

    I’ve even tried the shorting of pins on the 1xpcie on the mobo.

    Are they all duds or have I missed something?

    • M says:

      Are you powering the risers? I didn’t see that mentioned in your list.

      • Hocney says:

        Yes, I have tried them powered and unpowered. Using the sata power adaptor and also ditching the adaptor and going straight molex.

        Tried powering a single riser and gfx card on the same cable and on their own cable as well.

        These are gtx1070s that I am using, also tried 2 older 270x cards. I have grabbed a couple of rx580s today so I will try them when I wake up. Time for bed after a night shift.

        They can’t all be broken surely. Maybe I just have bad luck.

      You have the display plugged into gpu and not the mobo video? The onboard graphics will be disabled with the gpus connected

        I had the windows all setup before plugging in the GPUs. Should I setup windows again all the gpus plugged in?

        I had windows setup before all the gpus were plugged in. I had all the motherboard drivers and windows all updated. Plugged one gpu to get the driver to work.

        Should I formatted and install all the gpus and then install windows?

          You shouldn’t need to reformat windows. You still have your monitor plugged into the same gpu? Wondering if bad card or slot or riser? Maybe try just the one gpu that worked and see if windows will load again? Then try adding one gpu at a time?

            So I plugged in all the graphic card(nvidia 1070) directly to the motherboard (one at a time), works fine. Risers are all new, but don’t know how to check to see if they are fine.

            I plugged everything in and still blank screen.

            I have 1 molex cable to the psu(1200w), but 2 riser connected to 1 molex cable, thinking that I should mix it up with sata connection?

            Or thinking that not enough power….

            You still haven’t answered a few things. Do you have your monitor plugged into one of graphics cards or the motherboard? The on board graphics will be disabled so you need to plug into graphics card. Did you try turning it on again with just the one graphics card that worked originally to see if screen would show up? And if that does work then add one at a time and make sure it still works (able to turn on and see screen after each additional card added) until you find the problematic one.

            These are my specs:
            Biostar TB250-BTC
            4gb Ram
            120 ssd
            i3-6100T 3.2 Ghz lga1151 35w
            6x geforce 1070 gigabyte
            6x v007 riser
            Evga 1200w PSU

            I have plugged monitor into the graphic card that goes into the 16x slot on the motherboard. And nothing shows up. I tried plugging 1 graphic card with riser into the 16x slot and still nothing shows up. But when I plug the graphic card directly into the 16x slot it works fine.

            I have 1 molex cable that has 3 attachments, Can I connect 2 riser to, this should be fine, right?

            I have 2 risers per molex cable and mine works. Sounds like a bad riser possibly if the card works directly in the 16x slot but not connected with riser. Have you tried all the risers with just the one gpu to see if you can get display?

          • Deux says:

            Yes, I have went thru with each riser with each graphic card, and nothing display. I had a same thing with a MSI z170a-sli plus board… so maybe not enough power?

          • Static says:

            It might not be enough power? Do the cards look like they have power when you boot? Did you try each riser with only one card connected to make sure the risers work? Because you said the monitor displayed with the gpu connected straight to the 16x slot but not with the riser… Was that the only gpu connected or that was with all of them connected? If it worked with all gpu connected I would think bad riser, but could be too much power. I’m not sure how much extra power the risers use themselves. And I have mine on two 850s so I can’t help you out there. And I read another forum talk about using hdmi instead of vga if you are using vga you might try that.

            When I have it powered all the graphic card fans turn on, but then shut off sometimes and comes back on. This is the reason why I guessing that it doesn’t have enough power.

            I went thru with each riser, and all ok…

            What worked was resetting the CMOS… smh.. All 6 1070 CPU working!!!

          • Static says:

            Awesome! Sorry I couldn’t help out more. Funny though I just read another thread earlier about resetting cmos. Was gonna mention that or see what version of windows u had cause some don’t support 6 gpu. But glad you got it running. Good luck!

          • Static says:

            And not sure how many cards you have? But if you only have two one molex cable is fine and I have mine directly to risers with molex not sata. And 1200w should be plenty if all you have is 2 cards

    Not sure what happened..

    PSU – 1000w EVGA 1000GQ
    MB – ASRock B150M Pro 4
    RAM – Kingston Technology ValueRAM 4GB 2133MHz DDR4
    CPU – Intel BX80677G3930 7th Gen Celeron Desktop Processor
    GPU – EVGA GeForce GTX 1060 GAMING, ACX 2.0 (Single Fan), 6GB GDDR5, DX12 OSD Support (PXOC), Only 6.8 Inches Graphics Card 06G-P4-6161-KR
    Power Button – uxcell 67″ Desktop Computer Case Power Supply Reset HDD Button Switch

    Started with one GPU, had my SSD drive with windows 10 loaded and I couldn’t get anything to appear on my monitor. Powered down. Removed my GPU to allow the monitor to connect to the MB graphics, restarted. Heard a loud “pop”, saw sparks and smoke from the PSU and now it’s dead.

    Thoughts?
