This script was made to simplify overclocking using amdgpu's hwmon interface. It's nice that the hwmon interface is so simple, but it's not something you can realistically use without scripting, so this script is meant to fill the gap. It will find the hwmon path for a given vendor and product ID and set the overclocking profile provided in /etc/pyoc.json, which is just the vid:pid and a set of commands to set the overclock, which are all outlined here.
-
Run
sudo make installto install the script to/usr/local/bin -
Run the command with
sudo pyocto generate the config. -
Edit the config at
/etc/pyoc.json(it's set up for a 6800 and 5700 XT with conservative overclocking and undervolting). -
Apply the overclock by running
sudo pyoc VENDOR:PRODUCT, where VENDOR and PRODUCT are the vendor and product IDs for your card.
If you don't want to manually run the OC script every time, you can use a udev rule to automatically apply the overclock when the card is bound to the amdgpu driver. Be aware that this is dangerous and can prevent your system from booting, and you may need to chroot in to delete the file. I only recommend doing this after you've verified that the overclock runs fine.
- Run
sudo make vendor=1002 product=73bf install-rulewith 1002 and 73bf being the vendor and product ID for your card.
