Warning: Ethereum(ETH) will migrate to PoS(Proof of Stake) algorithm in near future, maybe in a year. So jumping into ETH mining now might or might not be profitable. Also, I do NOT condone crypto mining with fossil fuel based energy source!
Prerequisite: A PC running on Ubuntu 20.04 with stable Internet connection
AMD RX 6600 XT is latest addition to the Big Navi product family. Below are the steps I managed to do ETH mining with a 6600 XT on Ubuntu 20.04.
Installing AMD Radeon Pro driver
# after the driver is downloaded, extract it with tar $ tar -xvf amdgpu-pro-21.30-1290604-ubuntu-20.04.tar.xz ... # install the pro version with OpenCL support $ cd amdgpu-pro-21.30-1290604-ubuntu-20.04/ $ ./amdgpu-pro-install -y --opencl=rocr,legacy # add current user to video and render group $ sudo usermod -a -G video $LOGNAME $ sudo usermod -a -G render $LOGNAME # reboot to load the driver $ sudo reboot ... # install clinfo to check if OpenCL is enabled properly $ sudo apt install clinfo $ clinfo ... Number of devices 1 Device Name gfx1032 ... # success!
Build rocm_smi_lib to set power limit, memory clock speed, etc
With nVidia’s Linux driver, there’s a bundled tool
nvidia-smi to control the card’s power limit, etc. But that’s missing from AMD’s driver bundle. Thanks to Radeon Open Compute the rocm_smi_lib is here. It’s source code so I need to build it myself, but it’s quite straight forward.
# install dependencies $ sudo apt install cmake g++ # clone the github repo $ git clone https://github.com/RadeonOpenCompute/rocm_smi_lib.git # start the build $ cd rocm_smi_lib/ $ mkdir build $ cd build $ cmake .. ... $ make ... $ sudo make install ... # set max power to 55W for the first card $ /opt/rocm/bin/rocm-smi -d 0 --setpoweroverdrive 55 # check result $ /opt/rocm/bin/rocm-smi ======================= ROCm System Management Interface ======================= ================================= Concise Info ================================= GPU Temp AvgPwr SCLK MCLK Fan Perf PwrCap VRAM% GPU% 0 55.0c 54.0W 920Mhz 1000Mhz 22.75% auto 55.0W 61% 99% ================================================================================ ============================= End of ROCm SMI Log ==============================
Install and Start TeamRed Miner
This is the most easy part but has to be done the last 🙂 The latest release can be downloaded here and commands to get the mining started are below
# in Downloads directory $ tar xvf teamredminer-v0.8.4-linux.tgz ... $ mv teamredminer-v0.8.4-linux ~/ $ cd ~/teamredminer-v0.8.4-linux/ # in start_eth.sh, replace the ETH wallet address to yours otherwise you will be mining for someone else :) $ vim start_eth.sh ... # start mining! $ ./start_eth.sh [2021-08-22 10:06:25] Pool asia1.ethermine.org received new job. (job_id: 0x65d72f5b396..., diff 1.000 / 4295 MH) ...
If this actually helped you, you’re welcome to support my blogging by running your mining rig with my wallet( 0x0016a5e2d5a32d40f89475218427d35798d05d8a ) for a few hours. Or maybe just click on an ad. which is much easier.
EDIT: It seemed when 2 6600 XT cards are plugged in only 1 of them becomes available to OpenCL.
