Building an Ethereum Mining Rig - Part 2

First update to the guide "Building a 6Gpu Mining Rig for Ethereum" - Let's talk about Claymore.

This update supplements and does not replace the Guide to Build a 6GPU Mining Rig for Ethereum published on our site.

The substantial differences are due to the installation of the latest version of the Windows 10 Operating System, the mining on the Ethermine pool (in our opinion simpler than Dwarfpool) and the use of the XFX RX 580 8gb GPUs.

The first variant is found in Part 4 of the guide: the environment variables are not to be entered as they will be integrated directly into the bat file to start mining.

The second variant is found in Part 7 of the guide and leads us to "mine" on a different pool using the Claymore software.

Download the latest version at the following link: https://github.com/Claymore-Dual/Claymore-Dual-Miner

Once downloaded, unzip everything on a folder on your desktop and open the start.bat file with notepad. Clear the contents and copy the following command:

start config.dll -epool eu1.ethermine.org:14444 -ewal "your ETH wallet address" -epsw x -worker "worker"

EthDcrMiner64.exe

Where instead of "your wallet address" you will have to put your Ethererum wallet - obviously without the quotes - and instead of worker you will put an identification number in case you build more RIGs (such as RIG1, RIG2, etc ...). We opted for the eu1 pool even if some on the discussion forums believe that the us1 is more profitable.

At the following link, many other useful commands for your Rig:

The Ethermine pool offers a very well crafted and descriptive interface. In the Payouts section, after only 5 minutes of mining, you can decide the minimum amount of Ether to be transferred to your wallet by simply entering the IP address of the RIG.

We have decided to mine directly on the Ethereum address of our Exodus wallet. It is not recommended to mine directly on Coinbase, as reported on the site itself. Sin.

Nothing should be left to chance when you decide to build a mining rig for Ethereum.

The third variant is the most difficult of all. Once you have reached Part 5 of the guide, you can decide whether to continue or follow this update / variant. If you are here it is probably because you have run into some problem that the guide does not allow you to solve.

With the latest version of Windows 10, you may run into a kernel conflict between the operating system and AMD's Radeon Software Crimson ReLive Edition Beta for Blockchain Compute drivers. This conflict will prevent you from using Atiflash after installing the drivers.

Important: Before making any changes to the BIOS, please backup each GPU.

Important: first of all flash the GPUs with the original bios if for any reason you are forced to reinstall the operating system.

Still on Atiflash.

The advice would therefore be to flash the GPUs and then install the AMD drivers. Let's say it would be because you may run into another problem this time related to the GPUs themselves. Since each video card is different from any other, the bios mod of the GPU could crash the operating system showing the classic blue screen and displaying an error related to the Atimkdag.sys file.

This could be due to the fact that some GPUs have significantly higher performance in the calculation phase than others. We could call it a factory overclock but not using them for gaming we cannot say it with absolute certainty.

Having assessed these two drawbacks, the only safe solution is to flash all the GPUs, disconnect them except for the first one, install the Blockchain drivers (plus Atimkdag patch) and launch the mining command verifying that the operating system does not go into crash in the next 5 minutes.

Turn off the rig again and connect the second GPU so on up to the sixth. In the event that one or more video cards should crash the system, disconnect them. After that, it uses DDU from the provisional mode and flashes these GPUs with their original bios. At this point, connect them again, reinstall the Blockcain drivers (plus Atimkdag patch) and start mining definitively.

All the operations related to the use of Atiflash, DDU and driver installation are reported in Part 5 and Part 6 of our guide.

A little bit of Overclocking.

You will certainly find significant differences in performance between the GPUs.

At this point all that remains is to "operate" with an overclocking software. We opt for OverdriveNtool. Our constantly updated guide is available at the following link: https://www.cryptoall.it/2019/10/12/complete-guide-to-overdriventool/

Link to the official YouTube channel for verification: https://www.youtube.com/channel/UCdE9TTHAOtyKxy59rALSprA

GPUs with modified bios will not leave much room for modification. You will have to proceed with the most extreme overclocking on those that mount the original bios; obviously always in small steps by saving the profile for each GPU. Our guide explains in detail how to do it.

Hoping to have been of help, we give everyone an appointment for the second part of the update on how to build an Ethereum mining rig in which we will explain in detail the dual mining on the Ethermine pool.

See you soon.
