Tutorial: Ethereum Mining Rig Part 1 (choosing the parts)

Ledger Wallet protects your bitcoins


As i mentioned in my first post here in the last 2-3 weeks i have been looking to get the best parts for my mining rig. Ill try to be straight on the subject with all of my posts.. so here is what i have selected for my first mining rig:

Motherboard : ASRock H97 Anniversary (

ย Many miners use ASRock H81 Pro BTC which i have also selected it in the first run but then i decided to go with ASRock H97 Annyversary (specs) because of new chipsets and it can be sold easily after i am done with mining (if ever comes to that).

The Asrock H97 Anniversary (ASRock ATX DDR3 1066 LGA 1150 Motherboard H97 ANNIVERSARY) comes equipped with PCIe 3.0 x16 slots, but the Asrock H81 Pro BTC comes with PCIe 2.0 x16 slots. Even though, currently, the performance difference is negligible, the H81 Pro BTC may not be able to keep up with advancements in GPU technology in the further future. Check here for full comparison

UPDATE: November 16, 2016


Decided to update this post and to add the newest video cards as best option for your rig, this two cards are the best value hash/cash/consumption.

AMD Radeon RX 480 (

You can find my latest Ethereum mining rig build with the RX 480 video cards here:

Same rig here but switched to mine ZCash can be viewed here:

AMD Radeon RX 470 (

I did not build any rig with this cards but you can check some reviews here:

IMPORTANT: If you are going to have a rig of 6x cards with one of this two, then you will have to get a much powerful PSU and which i recommend this one


Before to continue further, please share this ๐Ÿ™‚ thanks!

GPU/Video Card: 4-6 Radeon R9 380 4g (

I think that the Radeon R9 380 and 380x are the best video cards for mining, watt consumption is somewhere at 200watt. One R9 380 can mine on average 20MH/s.

Radeon R7 370 4GBย  (

I decided to change GPU and instead of R9 380 ill choose R7 370 (after more researches i found out that this are the best performance per hash/cost/power out there), to more specific ill buy the following ASUS STRIX R7 370ย .

If you decide to go with R9 380 then you will have to buy a more powerful PSU, 1600W like EVGA SuperNOVA 1600 G2 80+ GOLD, 1600W Fully Modular NVIDIA SLI and Crossfire Ready 10 Year Warranty Power Supply 120-G2-1600-X1 (

CPU/Processor: Intel Pentium Dual-Core G3258 3.2GHz (

Intel G3258 4 Pentium 3.20 GHz 3M Cache 2 Core Processor (BX80646G3258)
Compatible with Intel 8 or 9 series Chipsets
LGA 1150
2 cores
3.2Ghz base frequency

RAM/Memory: 1x HyperX Fury Black 8GB DDR3 1600 MHz (

Kingston HyperX FURY 8GB 1600MHz DDR3 CL10 DIMM – Black (HX316C10FB/8)
Asymmetric heat spreader for stylish heat dissipation
Compatible with Intel and AMD platforms
Easy to install – Plug-and-Play functionality

SSD/HDD: ethOS 16gb SSD ( (already ordered) UNBOXING VIDEO AND IMAGES

ethOS - Ethereum Mining PlatformWhat is ethOs ? It’s a 64-bit Ubuntu distro already configured to mine. You buy and copy the digital image to an ssd or buy an ssd with the digital image pre-loaded. Basically this is the easiest way to start mining for a very beginner like me. Read more about the project here.

I will post an unboxing video soon!

PSU/Power Supply: EVGA SuperNOVA 1600W G2 (

Some people say that a 1300W psu is enough for a 6xgpu rig. I just decided to use 2 PSUs because i will not have the money to buy all of my GPUs at once.. so i will start with one 850W and once i add more video cards ill buy the second PSU of 850W or 750W.

With this new GPUs the consumption for 6x R7 370 will be somewhere between 860w an 900w so basically the 1600w PSU is too much and i had to look for a new one, i choose Corsair RM1000x 80+ Gold Certificate 1000w

Corsair RM1000 80+ Gold Certificate 1000w (

Corsair RMx Series, RM1000x, 1000W, Fully Modular Power Supply, 80+ Gold Certified, 10 year warranty

Part 2: Building the frame
  • Spencer Tarring

    Hi, you’ve listed 4 different GPUs in this, so confusing to see which one you actually got! I bought R9 370’s, but i can only get 12.5MH/s out of them. Not sure if thats the config, motherboard or drivers, but obviously its only 60% of what I’m aiming for. Could you confirm if the R7 370 is better?

    • Yes, i got the same GPU, Asus Strix r7 370 4gb. I had the same MH/s out of the box, you shoud increase globalcore to 1175 and globalmem to 1600 and you will get up to 16 MH/s. Do you use ethOS ? ill add soon a tutorial dedicated to ethOS! here are my settings at the moment running like this for more than 12 hours, no crashes

      • Spencer Tarring

        Damn I just took them all back and upgraded to the more expensive R9 380 (PowerColor). I don’t know how to change the global core and globalmem how can I do that and what do you recommend for my new 380’s!

        p.s. one annoying thing i have noticed already is that each GPU now requires two power cables, not one.. bit of an ass!

        • No worries, 380 are just fine, can pull around 20MH/s, i was about to get them too. My next rig will be with 380 only!!

          Will you use ethOS ?

          Some cards must be connected with 2 power cables, and i think because those pull more watt and needs to have more power.

          Have you also got another PSU (Power Supply Unit)?

          I have seen 127 mh/s core=800 mem=1500 1100w

          • Spencer Tarring

            I’ve got a 1000W in one right and a 1200W for another. Ideally I wanted to run at least 5 x 380’s (which I have). But i want to try and optimise one first, I don’t think 20MH/s is as high as it can go.

            Also, Im having trouble with dwarfpool, how the hell do I submit my email to get stats etc? I’ve reverted to using the GUI miner from Minergate which is no where near as efficient.

            I don’t have EthOS, you recommend it? I just bought a copy I’m waiting for them to send me the digital download link!

          • I think you can run 5x r9 380 with 1000w PSU do you have a watt meter like kill a watt ?

            I use ethermine and yes, ill recommend ethOS it is very easy to use and ready configured for mining ethereum, just have to add your wallet and to play with settings, that’s it.

            do you use skype ?

          • Spencer Tarring

            No, i don’t know about the extra add in programs, i’ll try them out. What i really need to figure is how to change globalmem etc.. fancy sending me a copy of EthOS? I paid and they still haven’t given me the download link. My Skype is spencertarring

          • added you to skype!

  • Spencer Tarring

    Also the motherboard you listed only has 1 PCIe x16 and 4 PCIe x1 slots, so how are you running 6 GPUs

    • Hey Spencer,

      The motherboard has 1 x PCI Express 3.0 x16 Slot (PCIE2: x16 mode and 5 x PCI Express 2.0 x1 Slots , here, check this image , i have pointed all the slots. The image from amazon is small and in that position is a bit hard to see the slot that is located above pcie x16 slot.

      Hope this helps! thank you!

  • Cris

    Hi Ciprian can we use Gigabyte AMD r9 380x 4 gb

    • Hey Cris, yes the Gigabyte AMD r9 380x 4 gb will work perfect. One card should mine around 20mh/s.

      If you plan to get a 6 gpu rig make sure you buy a more powerful psu.

      • Cris

        Thanks Ciprian do you think on that 6 gpu rigs how many ethereum coin can be mine in one day ? And what psu will be compatible to use ?

        • Hi, this 1600w psu should be just fine for 6x r9 380x check this one here: , with this rig you will get around 25-30 eth monthly.

  • xtiante

    Hi, great guide, thinking of building one myself, though I’m still confused about which goes where, would this setup work with using 6x RX480? And would a 1100w PSU be enough? Wat sort of power connections would I need? I would assume 6x6pin for the cards and 6x4pin molex for the risers right?

    • Hey,

      Yes, this should work with 6x RX 480. You will see the cables marked as GPU so you will know which one is for GPU’s and risers, some risers can be powered via sata cable too!

      I will create a tutorial soon with the best configuration for RX 480 ones!!

  • Alohan Gold Nosakhare

    but a laptop with 4gb, core i5, external hard drive. will work right?

    • Only for it is a ssd one, yes will work

  • Alohan Gold Nosakhare

    to what do i connect ethos 16gb to? do i connect it to my laptop?

    please am kinda a newbie in all of this would like an image sketch or video on how to combine component parts.

    • Do you still need help? I’ll help you

  • Alohan Gold Nosakhare

    an ehos16gb only works with ubuntu? do i need to intall ubuntu in order to use ethos? i need y’all assistance thanks fam.

    • Sorry for the delay but for some reason I did not received notification about your comments :(.

      No end to install Ubuntu, write ethos image on ssd and plug he ssd on your rig. Check last tutorial part.

  • Alohan Gold Nosakhare

    do i need to replace or clone my hard drive to ssd or use the ssd externally?

  • Rachid Abbal

    i really thank for your time explaining all that, my question is how to install and confgure ethOS on my pc, i have a windows 7 64bit. and i have an HDD 500 Go on it, or i have to buy an SSD one?

    • Hi Rachid, is highly recommended to install ethos on a ssd, do not use hdd. You can buy a 16gb ssd, that is enough, I also have a 16gb ssd.

      • Rachid Abbal

        Thank u, im about to reading your fourth chapiter , installing Ethos.

        • Awesome! What GPUS you got ?

          • Rachid Abbal

            i commended AMD Radeon Rx 480.

          • Perfect, have you got a bigger psu?

          • Rachid Abbal

            sorry i’m late for answering, For the PSU i’ve bought two TooQ TQEP-700SP 700W do you think its sufficient ??

          • On my 480s rig I have a corsair 1200w gold and toral consumption on ethereum is 900w, zcash 750 800. You should get a 1100w, is good have a little extra.

          • Rachid Abbal

            as i mentioned i have 2 * 700W that means i do have 1400w in total, not 700w.

          • Oh hh sorry my bad :D, then you are ready to go.. ๐Ÿ™‚ there is enough power

  • mher1

    hello im having difficulty getting my rig to boot up i have gotten the CPU fan to come on and seem to have all the connections in place but can’t get it to recognize anything. no display on monitor just stays in power saving mode I’m not the smartest when it come to computer stuff so am in need of help.

    • Hey… try to remove everything from motherboard and start it with one by one. Hdd, rams etc.. the add one single gpu.

    • Let me know if that worked…

      • mher1

        should i expect it to boot up at each stage till i find the malfunctioning component?

        • Yes, your monitor should display something if booting correctly.

      • mher1

        because i have everything disconnected but the monitor and when i power up all i get to confirm there is power to the MOBO is the CPU fan operating?

        • Send me a message or reply your Skype ID or whatsapp is much easier to communicate there ๐Ÿ™‚

          • mher1

            WhatsApp 19519733988

          • mher1

            or we can just text whichever is easier i can always Skype too just need to set it up seeing as i have iPhone

          • tried to add you to whatsapp but your contact is not listed :/ what is your skype ?

          • you can send it over the contact page:

          • mher1

            Skype should be the same I guess I just set up the account and that is what they say it should be. I sent it in the contact page as well

          • It worked, i just added you!

          • you must accept my request on skype.

          • mher1

            Ok so still not getting any results…

      • mher1

        Rig is now operating with six GPUs but keeps crashing and rebooting can’t keep it on what do you think is going on

  • bata grk

    Hi i am in need of your help,i am moving to a student dorm where i would have free electricity in a few days and would like to setup a eth mining rig with 2x rx470 8pin sapphire nitro+ oc 4gb cards.So i need your help about what motherboard and psu to get,was planning to use my old i3 cpu with 1155 bracket and 2x4gb 1333 mhz ram+1tb sata 2 ssd and old mini atx tower.Yes i know i could mine much more with pro btc mb and 6 cards but my room doesn’t have space or ac to support it .Motherboard can be second hand and I don’t plan to expand rig in the future so there is no need for a 1200w psu.Thx in advance

  • mbeh4sh

    I’m about to build my first 6 gpu rig and have done the purchase already. I went for the corsair rm1000 psu and got cold feet…maybe this is too small ? Gpu are MSI Gaming X RX 470 4GB version. Should I return and buy a 1300w psu instead ?


    • If you are not going to mine on dual then 1000w should be ok but still to tight and you will have to lower gpu and undervolt the cards for lowest power consumption.. anyway i recommend to get at least a 1200w psu like this one

      • mbeh4sh

        Many thanks for fast reply! I will strongly consider your recommendation! My new motherboard (Z170A GAMING PRO CARBON) also support 7 gpu so there is another reason for more power. My first idea was to start small with 2 gpu, look at the market and then buy 4 gpu at a later stage but now I’m more or less leaning torwards all in att start with 6 or 7 gpu’s.

        • If you are going with 7gpu then get 1300w or dual psu ๐Ÿ™‚

  • Christian Ulirsch

    Can I put multiple gpu types. My rig would have a two 470s, a 480 and a gtx 1060?

    • Yes you can put any 470s or 480s but not gtx..

      • Christian Ulirsch

        Can I also have 4 gb and 8 gb cards mixed? Also, you said previously that the bios configuration would need to be customized for each of them. Do you have a tutorial on that?

        • Hi, yes you can mix with 4gb or 8gb it will work with no problem. Yes i do have some tutorials but this will depends on what cardds you will get and what memory those will have.


      pascal based nividia chips work fine.. 900 series tho i needed win 7 and old drivers could not use my 970s in the same rig as my 1080TIs. regarding different gpus… get the latest driver all your gpus share in common. i have a rig with two 1080s two 1070s and 1060 all working just fine together. since my 970s didnt work on windows 10 with the latest drivers(low hash) i put those on win7 and used an old driver and wala. just build a seperate rig for your oddball cards wether itds becuase of driver or becuase its amd when ya also got mainly nvidia etc and add it as another worker

  • Kyle

    I have no idea what gpu to you to get all the sapphires are over priced. What is most I should pay for any type of 470 4gb or 480 8gb?

    • try to get 570 4gb nitro+ oc or 470 8gb nitro+ oc!

  • mdetrini

    In making a 6 board rig is it possible to have say 4 MSI RX580 and 1 MSI RX480 and 1 SAPPHIRE Vapor-X Radeon HD 7950 without any complications.

    • Hmm not really sure what to say about that but, for sure you must use latest drivers because of 500, and you apply the signature patch for modded bios. as for the 7950 no idea how it works with latest drivers..

  • Yuchen Feng
