Building a 12 GPU Mining Equipment with Sapphire RX570’s – Ordinary Mining OS
A little bit of background, I’ve bot building equipments and mining for approx Trio years now, you could almost say its my utter time job, but more importantly its my hobby :).
Skip to the end and download the BIOS Mod here.
Very first of all I am assuming you can already build a pc to a reasonable level. This postbode doesn’t voorkant things like CPU and RAM installs, just the more experienced side like flashing motherboards and GPUs, plus problem solving and best practises.
Also, if you are doing this from huis, you are very likely going to want an Open Air case. They are a loterijlot quieter. I use this style case because I need airflow te the facility.
1 x Case with Power Ventilatoren
12 x USB Risers
12 x Sapphire RX570 Pulse 8GB GPUs (with Hynix Memory)
Step 1 — Check all the risers
I find this to be absolutely essential to maintaining my sanity. Risers are the number one reason there are faults or non detected cards etc, so the very first thing I do is connect a GPU to the very first riser, power on the equipment, check it works, then budge that same GPU to every single riser one by one. Any riser not working, eliminate the problem by switching one component at a time (say the PCI houtvezelplaat, or the USB convertor) until you have 12 working PCI slots.
Step Two — Ensure you have the juist memory type noted
Every prototype of GPU comes with different types of memory. For example, the sapphire RX570 can be Hynix, Elpida, Samsung (the best IMO), etc etc.. So make sure you check this using GPU-z on your Windows machine. This matter straks on. If you have different types then you won’t be able to use the BIOS mod I’ve provided here, but you should be able to find it somewhere else on the web.
Step Trio — Download SMOS &, Flash
I’m using Plain Mining since its very effective at remote management, and does wagen updates with a cool panel. You can download and go after the instructions from their webstek here: www.simplemining.nipt .
Once downloaded, use a instrument such spil Etcher, or HDD Raw Copy Device to flash the .iso opstopping to your SSD. Once finished, edit the config opstopping and switch to your email address.
SMOS works on USB spil well, but I’ve found it to be problematic. Suggest using an SSD spil the price is not that much higher.
Step Four — Flash the Motherboard with the latest BIOS
Use this BIOS (or check the Biostar webstek) to flash your motherboard. Copy it to a USB and boot whilst pressing F12 continuously. Select the verkeersopstopping and flash.
Once flashed boot te the BIOS and make sure you set spil goes after:
Boot on power loss > On
Primary Graphics > IGFX
CSM Support > On (significant otherwise it will not boot SMOS)
Everything else should be fine to be left spil it is.
Step Five — Install the GPUs
Now you can start installing the GPUs. I normally do Two at a time, followed by a utter boot and test run to check for any errors. Saves having to go back and find a cracked card or something wrong straks on.
On very first boot SMOS will do all its update, and it might not fully boot, staying stuck with the repeating message “There is no miner to be attached”. Just disregard, restart and all should be fine. You can login to your panel at simplemining.nipt with your email and you can configure everything there.
Step 6 — Setting the configs
Ter SMOS Control Panel you can setup your equipments config. Ter this tutorial we’re covering mining ETH, but you can do pretty much anything by switching the group settings. The standard config line helps you get began, just switch your wallet address and your pool (hopefully you’ll use hivepool.io when wij are live) and the equipment will embark mining. Here is my sample config.
wd 1 -r 1 -epool eth-eu.hivepool.io:8008 -ewal $walletETH -eworker $rigName -esm 0 -epsw x -allpools 1 -asm 1 -dpool dcr.suprnova.cc:3252 -dwal alpha-redhive.main -dpsw password -mode 0 -dcoin dcr -dcri Legitimate
You will see that I am dual mining, ETH &, DCR which seems to be the most profitable at the uur. You can check this on a webpagina called WhatToMine.
Step 7 — Modding the GPU Bios
This is elaborate part that can sometimes harm cards. Please be very careful here. You can mod cards te Windows, SMOS, or EthOS using atiflash, a fine program when used well.
Absolutely essential, you save your original BIOS very first te case all goes wrong. Do this by SSHing to your SMOS equipment (you can get the IP address from the SMOS control panel by hovering overheen the equipment name). The username is ‘miner’ and the password is ‘miner’.
Once logged ter, type:
screen -x miner …. and then press ctrl+c few times until entire screen exits
This will display all your cards. Suggest you test one at a time. Very first of all save the bios by running:
sudo /root/utils/atiflash -s 0 original.rom
0 represents the very first GPU. Once saved you can go ahead and flash the bios, but you need to get the bios opstopping on the equipment very first :P. Download it here, then use windows directive to transfer it to your equipment:
pscp filename [email protected]:/root/utils/filename
It will ask for your password which is ‘miner’.
Now go back to Putty/SSH and run this guideline:
sudo /root/utils/atiflash -f -p 0 filename.rom
That will flash the card!
Reboot and see the switch te the hash rate, then perform for all the other cards.
Step 8— Overclock the Cards
I’ve bot overclocking my cards fairly cosily with the following settings:
Each card should get approx 30MH/s for ETH and 500+ for Decred. Ter total your equipment should be running around 360MH/s and 6000MH/s.
If you get some problems with the overclocking, identify the problem cards and just don’t overclock those ones. You can do that by putting this into the plain mining oc field:
For the above setting I waterput the 2nd card (GPU1) back to stock 2000 mem.
