This is the continuation of my complete guide about how to build an Ethereum/Zcash mining rig! Here is the first part (theory): it explains and justify the choices that have to be taken when building a mining rig. Once you’ve read the theoritical part – or if you’re just curious to see what I’ve set up – you can go and read the following 😉 How to build a Zcash / Ethereum mining rig?

• • • • • • • IV / Assembling the mining rig Before to set it up in a case 1/ Install the CPU on the motherboard – 2/ Install the CPU stock cooler – 3/ Plug the motherboard power connector – 4/ Install the RAM – 5/ Plug the push-button On/Off/Reset to the motherboard (google “front panel connectors”) – 6/ Connect a monitor to a VGA/DVI/HDMI port from the motherboard – 7/ Turn on the PSU, push the mobo button and check if the CPU fan is running and if the Bios logo is displayed on screen Before going further, the ultimate trick: zip ties! These little pieces of plastic are great to fix components or cables: it makes organization easy and allows saving lot of space for dissipation. Different sizes exist. Don’t hesitate to tighten it with a plier and cut the rest of the cable. Zip ties forever. Put all these components in their case now Imperatively use standoffs to fix the motherboard onto the bottom of your case (don’t stick it to the bottom awkwardly, mind the heat)!

Install the PSU with great care (as it’s heavy and bulky). Now, add the HDD/SSD. Gather, organize and fix all the cables with zip ties. Don’t forget to install at least one GPU so that the OS can retreive drivers automatically during the setup (Windows) and configure GPU’s output instead of the integrated graphics!

My mining rig I’ve used 2 plastic boxes bought in the storage department of a DIY store. It’s stackable and easy to cut. I’ve built it with two levels: one for the “desktop” components that heat the less (motherboard, PSU, HDD/SSD), and on top of that the “mining” part with the GPUs, in the open air. I’m quite satisfied with the “back panel”! V / Installing, configuring both the OS and the miner Preparing the bootable USB key for OS setup Download an OS image ( or for example). Pick one of your >8go USB keys (all data will be erased). If you’re on Windows, download and use a great tool such as.

If you’re on MacOS or GNU-Linux, use the terminal: # Look for the right device: you need to know its identifier! Diskutil list # For example, we'll say it's disk3. Unmount its volumes. Diskutil unmountDisk disk3 # Now copy the image file to the device sudo dd bs=4m if=PathToTheImageFile/TheImageFile.iso of=/dev/disk3 Note: don’t use Unetbootin alternative as you’ll end up with a non-standard installation menu.

Running the installation Plug the USB key, you’ll need to boot from the device at startup. Use a keyboard recognizable by the bios, and press “F11” (for example) to enter the bios when you turn on the system! Now, select the proper USB device to boot from: the installation process begins. For the rest of the process, no difficulty.

Note: you should have an Internet connection with Ethernet when running the installation, so it can activate your license or retreive updates. If you’re running a “netinstall” for GNU-Linux, it’s mandatory.

Installing the driver & the miner As we’re running AMD’s RX 470 here, we need the last AMD Catalyst driver available. For Windows, it’s part of the Radeon Sofware (with GUI, which you can even use for over/downclocking), whereas the Linux version is AmdGpuPro. Download and install the proper driver and reboot.

Verify if the image displayed is ok, check if you can change screen resolution as usual. Let’s go for the miner: do you remember the mining software you’ll need to install (cf.

If it’s close-sourced, then download the binaries (.exe file on Windows). If it’s open-sourced, then look for the setup installation how-to on Github: it’s often an issue of building sources from the git repository. Instructions are short but concise!

Don’t skip any step. Don’t forget to install all the dependencies.

Note:regardless whether you’re on Windows or GNU-Linux, update your system before trying to install any mining software. Just use the slooooow Windows Update, and if you’re lucky go for this: sudo apt-get update sudo apt-get dist-upgrade.

Building the mining software from source may take a while, be patient 🙂 Moment of truth: have you succeed the whole thing? A miner comes with a lot of parameters. As most part of them are command line softwares, you’re going to “cook” your own start instruction manually and then enter it in the terminal.

To do so, you can learn from your miningpool’s how-to: it’s a good basis. Of course focus on the main parameter: your ETH/ZEC deposit address! If you want to know all the parameters available, use the command “[executable] –help”. Does the miner start? Does it detect all GPUs? If you read “GPU 0, 1, 2, etc.” or the series name of the gpu (Ellesmere / Polaris 10 for the RX 470), then it’s a good point.

Does it connect to the stratum server? It will take a few seconds to sync and fill your GPU’s memory. Now it’s supposed to mine: your miner has received a work. Note:the only hashrate that matters is the one given by your pool. Disappointed with your mining rig’s performance?

See section VI! Write a script to trigger the mining process Instead of entering the same instruction “[executable] + [parameters]” in the terminal each time you want to start mining, you should definitely write a script. Go and google the basics.

You may also find the following instructions on forums or miningpool get-started pages, dealing with environment variables: they are not necessary but appreciated. Setx GPU_FORCE_64BIT_PTR 0 setx GPU_MAX_HEAP_SIZE 100 setx GPU_USE_SYNC_OBJECTS 1 setx GPU_MAX_ALLOC_PERCENT 100 GNU-Linux version: export GPU_FORCE_64BIT_PTR=0 export GPU_MAX_HEAP_SIZE=100 export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 export GPU_SINGLE_ALLOC_PERCENT=100 VI / What’s next? Performance and optimizations Run the mining script at startup On Windows, create a shortcut of the.exe you want to trigger and use the “Execute” utilitary to run the command “shell:startup”: the startup folder opens up, so you can drag-and-drop the shortcut. On GNU-Linux, you should configure a Cron task!

Force restarting your rig after power failure A bios feature. Enter your bios and look for any motherboard/chipset configuration menu: the parameter should be something like “ After Power Failure State“. Set it to “ Power On“. Try the dual mining This is a feature available on Claymore’s dual miner: you can mine both Ethereum and (DCR) / (SC) / Credits (LBC) at the same time. It’s allowed by the use of the same POW algorithm.

Note that dual mining is far more tough on your GPU ressources, so it tends to draw more power. At the time of writing this post, it’s not worth dual mining for those who pay their electricity, since the prices for the dual-mined currencies have reached the profitability limit.

GPU memory overclock Definitely the first trick to apply to your GPUs. It enables a dramatic increase in hashrate. You need a dedicated software to change the frequency values and it will set them automatically at each startup. Overclocking is quite a Windows’ thing.

Linuxers should agree. Try for example.

In the case of the AMD RX family, the that embeds the WattMan utilitary will be fine! Supercomputer Verge XVG Mining. Note:testing values when overclocking your memory will cause driver failures and serious display bugs, even an outright shutdown. Don’t worry, and take your time.

GPU Core downvolting On the same overclocking software, try and downvolt your cores. Well, it’s directly tied to power consumption. Nice thing when you want to optimize your ROI. Keep in mind that lower voltage means less stability, unless you downclock your core as well. Proposals for advanced users only As suggested by, you can install a standalone to optimize your submissions to the network.

Another trick is to change some parameters in your miner (here ethminer/genoil): --farm-recheck, --cl-local-work, --cl-global-work. Make sure to understand what these values mean. VII / References anda lot of.
