Before to continue further, please share this 🙂 thanks!

Let’s get started

Preparing the motherboard

Unbox the motherboard carefully and keep the red material under it. The remove the black plastic protection from CPU slot.

Installing the CPU, Cooler & RAM

Once unboxed, get the cooler and remove thermal paste from it. Install the CPU and then apply thermal paste to it, final step is to install the cooler.

Frame, PSU and Motherboard

Now that we are all set with the motherboard and the frame let’s unbox the PSU. Then place the Motherboard in the center of the frame and the PSU in the left back corner.

Prepare the following cables:

  1. 24 PIN ATX
  2. CPU
  3. 4x PCI-e
  4. 2-3 Molex
  5. 1 Sata
  6. Power switch
  7. Ethernet cable
  8. And also do not forget about the keyboard 🙂

Once you have all the cables, begin to install them in PSU and motherboard.

(in motherboard you MUST have 1x Power Switch cable, 1x CPU cable, 1x 24 PIN ATX cable and one MOLEX cable that will give more power to PCI-e slots CHECK THIS IMAGE )

GPU Installation

I highly recommend  to install the GPUs one by one and test them, follow the next steps to make sure that everything will work fine.

  1. DO NOT install the SSD/ethOS yet
  2. Plug in the PSU, make sure you also plug in the watt usage monitor (if you have one)
  3. Install 1 GPU ONLY , turn on the PSU, power up the rig and make sure that it is booting correctly.
  4. Now install the SSD and turn on the rig (video tutorial: how to write ethOS image on SSD), wait for full boot and an error with WRONG DRIVER text will be displayed in terminal will be displayed (like in this image). You will have to access the local.conf file, type in terminal “nano local.conf” and below “globalfan 85” add “globaldriver amdgpu”, save the file by pressing CTR+O and them hit ENTER,exit with CTRL + X and reboot. Now the mining should start with no problem for your 1 GPU (23.xx mh/s)
  5. Success boot and mining for the 1st gpu? Great! Now install the second GPU and follow the same steps till you have all 6 GPU installed and working (in this way is very easy to find if a USB riser or Molex is not functioning correctly or the video card has a problem)

Rig is not booting with one GPU ?

  1. Double check cables (from psu and motherboard)
  2. Make sure CPU cooler is good placed and is not moving
  3. Make sure that the RAM fits good in the slot, if still doesn’t boot change the slot
  4. Check the jumpers for power switch if this is placed correctly

ethOS is not booting ?

  1. Black screen? Shutdown and start it again
  2. Is booting but the mining process is not starting? Shutdown and start it again
  3. All GPU installed but one keeps crashing or one GPU is always crashing, ethOS version is 1.1.1? No worries, new version will be released (1.1.2) and that will fix this problems, also more features for RX 4xx series will be available)
  4. Mining process not starting at all ? type “helpme” in terminal, copy the generated link and send it to mirc chat #ethereumOS

Everything is running perfect!? Great! Let’s configure ethOS

I had no problems, everything went nice a smooth from the beginning to the end, no riser/molex/sata/etc problem. Only that a card keeps crashing but like i said this will be fixed with the new ethOS release 1.1.2. I am too lazy to make this rig on windows, ethOS is much better, simple setup, easy configuration etc no headache on finding the right clocks and mems.. The screenshot of Watt usage meter is for 5 GPUs only, i forgot to take a photo with all 6 :/ but is somewhere around 900w.

OK, so we are all good, first of all we will need to configure ethos. Follow this steps

  • Update ethOS to the latest version
    This can be done by typing the command sudo ethos-update && sleep 5 && sudo reboot in the black window. Now hit the enter button and do not interrupt the process of update.
  • Set ethOS to the single rig mode
    Run this command to make the remote file completely blank echo -n "" > /home/ethos/remote.conf
  • Changing ethOS password
    a) In terminal type passwd and you will see “Changing password for ethos.”
    b) Type default/current password which is “live”
    c) Then type your preferred password twice and that’s it, we secured the rig.
  • Run the command nano local.conf and the default settings will be listed like in the image below.
  • maxgputemp 85 leave it default for now. This number means that this is the maximum temperature your GPU should reach when the system automatically stops the miner.
  • stratumproxy enabled this is a default command and should not modify it.
  • Using arrows go down to proxywallet and change the address with yours.
  • On proxypool you will see it in 2 lines, proxypool1 and proxypool2, it is because the second link is as a backup and if proxypool1 has connection problems or is down for any other reason then ethOS will connect to proxywallet2. If you are located in EU change proxywallet1 to this one: eu1.ethermine.org:4444
  • Save new modifications by pressing CTRL+O then ENTER. CTRL+X to exit local.conf file.

Here is my configuration file

img-20161009-wa0000

update: –cl-global-work 8192 should be changed to –cl-global-work 16384

Here it is, up an running. Currently i am waiting for the new ethOS version 1.1.2 (now using 1.1.1). The problem now is that i can only run with sotck settings, so no overclock till the 1.1.2 version with more support for rx 4xx series.

  • Hash power (stock settings): 140 mh/s
  • Power consumption (no overclock): 915w
  • Max GPU temp (near to open window, 40%-50% global fan): 55-60 °C

I will continue to update this post when the new ethOS version released, with overclock, hashing power, power consumption and much more, don’t forget to subscribe.

UPDATE: October 18 2016

The new ethOS 1.1.2 version is out since 8 october, i am still doing tests and ill show what i got till now but first of all let’s see what is new in ethOS

  • Added better stability, overclocking, and driver support for RX 400 series with new linux kernel. (the most important)
  • Dramatically reduced size of ethOS by removing unused packages and caches.
  • Reduced ethOS updater size.
  • http://ethosdistro.com/changelog/

So now we are able to overclock our cards, here is what i did.

I am having serious problems, one card keeps crashing, not sure why but i am still testing and checking to find the best core mem for this, so if one or two cards keep failing try to change usb risers recheck all the cables, maybe v 1.1.2 is not that stable yet but we can do a lot more things than previous version so maybe we can find the best core mem for our cards (for now).

First of all try to add “globalmem 2150” in local. conf (type “nano local.conf” in terminal). Core settings should remain default (do not add them). Leave it to run like for about 1-2 hours and if everything goes good increase the mem to “2225” and leave it like this for a while (significant mh/s will be visible).

Thank you for reading. As always, your comments, suggestions and questions are welcome.

  • Scuba

    Could you tell me what the hash rate would be for zcash? Genesis Mining is selling it by H/S. Could you tell me what the output would be in H/S please?

    • Hey @disqus_XwtZqW27zq:disqus

      Currently the best public perf/W & perf/$ is RX470 4GB in Win7 using
      zcashgpuclient_silentarmy with a modded BIOS that brings it up to
      ~40Sol/s. The best miner/kernel/BIOS/GPU model/RAM size will probably
      change over time but for current-gen HW IMO AMD will remain ahead of
      NVIDIA.

      So ill recommend RX 470/480! 🙂

      • Scuba

        40 sol/s or 40 h/s ?
        Genesis Mining uses H/S to determine the power. Is this correct? H/S?

      • Scuba

        Are you saying only one card produces 40 sol/s? What is a sol? Is it the same as H/s? Genesis Mining is charging $1866.68 for 40 H/s.

        • Scuba
          • Genesis mining is a rip off 🙁 you better invest in a tiny rig than rent from there 🙂 they are overpriced, but this is just my opinion and from what i read from other people.

            With a modded rx 470 you can get like 40 Sols/s but with a non modded around 30-35 Sols/s, i am not telling from self experience, i did not tested them yet, but i am telling you from what other users reported. I will do a test later today with r7 370.

          • Scuba

            How many cards can you hook up to one motherboard? I’m looking at wanting to build a large rig. I’d like to get 1000 H/s or so. Please advise.

          • You can go up to 6 cards. You want to mine ethereum or zcash?

            To achieve 1000 mh/s on ethereum you will need around 6-7 rigs.

          • Scuba

            I want to mine zcash. What will I need for that at 1000 h/s or 1000 mh/s? So 6 cards per rig? 6 to 7 rigs?

          • Yes, that’s correct! 🙂

          • Scuba

            And what would it cost in power consumption every month for one rig with 6 cards? What is the total wattage?

          • Scuba

            And this software pays directly in zcash?

          • Yes, they just updated the software and now is supporting zcash too. I’ll be posting a tutorial soon.

          • Scuba

            So 1100w per one rig at around what 10 cents a minute…so about $80 a month extra a month for electricity? What about the processor and RAM. How important is that when using the GPU cards? Or does it purely run on these GPU cards. I’d like to have the max 40 sols. What do you recommend in regards to motherboard, CPU, and RAM in order to achieve this?

          • Up to 1000w – 1100w per one rig. Right now my rig goes up to 980w.

  • Johan Pieterse

    Your hash power was 140 MH/s before the update. After update?

    • 140 was at stock settings, at what update are you referring to ? 1.1.4 with silentarmy update?

      • Johan Pieterse

        Yes.
        Although an indication on impact on hashrate per update would have been great.

        • Check my latest post with the last update , now mining ZCASH at 500h/s

          • Johan Pieterse

            You started at 140 MH/s for ETH. I wanted to understand your progress from that reference point.
            ZCASH at 500h/s is beside the point.

  • johnnyc

    great tutorial!

    also, with ethos 1.1.6 and optiminer you can easily obtain 130 Sol/s with an RX 480 and 110 Sol/s with an RX 470…

    • I did not yet tested the 480s with the last estate update. If that is true then this is nuts 🙂 I have only updated my 370s but I had the same speed.

  • Rachid Abbal

    Hello again i do have a question, that u mentied to change to single rig mode why? I found it in a several tutorial, can u explain me that matter plz. Thanks un advance.

    • Do you have more than one rig ?

      • Rachid Abbal

        No juste one by now, but im expecting receiving second one next week.

  • Juan P Ramos

    Are these GPUs on that configuration, taking advantage of Crossfire mode?. Are there any performance losses when using these PCI 1x ports?

    • Hey Juan, there is no Crossfire mode and there is no loss when plugged in 1x ports.

      • Juan P Ramos

        Thanks for your answer, then the use of 16X PCI slots and Crossfire is irrelevant for mining? Well I think the use of crossfire maybe is not important, but I’m not sure about there are not performance losses when you use PCI x1, because it has 16 times less bandwidth than an x16 port, also I understand the use of a multicore processor is better to manage this kind of GPUs, but probably it is also irrelevant, are you have made essays with this?

        • have you received my reply on this? i cannot see it and i answered to your questions. please let me know..

  • Elio Pashaj

    Dear friend. I am planning to build a mining rig with 6x Amd PowerColor Rx 480 8GB. They require each 500 watt minimum. What PSU will be handle all of them? Maybe its better to use 2x PSU? I am very confused because each of GPU require 500 watt minimum and i can’t decide the proper PSU to handle them. Thank you

    • Hey Elio! There is no way that an rx 480 will eat that much power. Maybe from where you got the information they recommend a system with 500w psu. Am 1200 or 1300 psu will be more than enough. I have 1200w.

      • Elio Pashaj

        Dear Ciprian, i asked because i saw that you used 1200w PSU for your 6x Sapphire cards. Another question which i am not sure is how to calculate the total power consumption by whole system. I made some calculation online and my system consumes 859 watt. This is the power consumed in 1 hour or 24 hour? Because i need to make a prediction on how money will i use for electricity.
        Thanx man. I appreciate your help and when i gain my first ether i will send you to buy a beer 😉

        • Total power consumed will be MAX 950w but you will stay somewhere 850w-900w hourly. Around $60 monthly electricity bill. Check this calculator https://www.cryptocompare.com/mining/calculator/eth , your max hashing speed with 6x rx 480 8gb is 150MH/s, overclocked 850w to 950w max. enter your cost per KW/h and you will see the profits and how much you will pay the electricity bill.

          My recommendation is to go with 6x sapphire nitro+ RX 470 4GB, modded bios, undervolted, 28-29 mh/s 70w per card 🙂 around 750w. with the same speed as rx 480 8gb. also there is a big price difference. I just hot 3 rx 470 on sale, i saved $150. Wait for the best moment to buy them or check every store possible.

          If you want to discuss more contact me on facebook: https://www.facebook.com/1stminingrig/

          • Elio Pashaj

            Thanx Ciprien i will go with your opinion. I saw that Amd Red Devil RX 480 has an 30.5 Mh/s. I think this is OC. Is that right?

          • yes 🙂

          • Raffo

            Hi Ciprian. Sorry but something is not clear for me.. Considering your hardware rig configuration costs (about 2000$ + with today prices (?)), mining with this rig configuration cannot be never profitable or never economically convenient as we can see on https://www.cryptocompare.com/mining/calculator/eth?HashingPower=150&HashingUnit=MH%2Fs&PowerConsumption=0&CostPerkWh=0

            Even if i don’t pay for electricity (impossible! it’s just a test)..
            150MH/s give me a risible profit per day of $ 8.24 (??!!)

            So two conclusions:

            1) There is something enormously wrong in my reasoning.. (i really hope so).

            2) If my reasoning is correct, someone tells me who, why and how can earn considering hardware and power costs !!

            Sorry but i’m really confused 🙁 with $ 8.24 at best i can buy a beer and coffee 🙁

          • those calculation were made few months a go when difficulty was low.. but now because eth went down $150 and difficulty increased really high… yeah.. the income is much less.. BUT this is for now 🙂 is good to have some eth mined.. soon the price will be very high :).. so it may not be very profitable NOW but it will be after few months..

          • Raffo

            So, you are saying me that beyond the current profit, that is better to mine than not to do it at all 😀 .. I Agree! 😉
            Me and some friends are really interested in mining. What can you recommend us for buying video cards. Which video card, and which cripto you feel us to consider today in prevision of an investment of about $ 40,000 in hardware? Obviously buying video cards available right away and not in six months 😀
            We believe that with such investment we can reach $ 100 a day roughly.. without considering power cost that in our location is about $ 0.07 / 0.09 kWh for business.

            Thank you very much

          • Umm I’ll go with any 580s or 1070s 🙂 also you should consider some good ASIC miners like L32and D3, check my reviews

          • Raffo

            Sorry for delay. Sure, i’ve to see your reviews, especially about D3. Really thank you again.

  • Carlos Fernandez

    hi i mount 1st rig with rx 480 sapphire, but the screen is black, the fans run , the graphics cards also but the screen nothing, im use hdmi cable depend on it? need dvi cable?

  • Stéphane Dréan

    Hi ! on ethos with sapphire radeon nitro+ rx 470 4gb. How much Mhz on mem clock and coreclock and globalpowertune ?
    Please.

  • Marcin Kretkowski

    Hi ! I have question about OS. What you recomende for such minning rig. Would you still go with Ethos or change to Windows.

  • Monty Lennie

    I couldn’t find any sapphire nitro so I bought AMD rx 480 8gb. Would the AMD GPUs still work with the rest of the hardware you listed here? Can the AMDs be modified also? Thanks https://www.amazon.com/gp/product/B073646STC/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
