To undervolt your AMD GPU on Ubuntu 24.04.1 LTS with the 6.8.0-51 generic kernel, you can follow these steps:
- First, ensure you have the necessary tools installed:
sudo apt-get install git
- Clone the AMDGPU undervolt script repository:
git clone https://github.com/Rodolfo-Castro/amdgpu-undervolt.git
- Change to the cloned directory:
cd amdgpu-undervolt
- Make the script executable:
chmod +x amdgpu-undervolt.sh
- Run the script with your desired voltage:
sudo ./amdgpu-undervolt.sh -p 950
Replace 950 with your desired voltage. You can find suitable voltages for your GPU model on the AMDGPU Undervolt GitHub page.
- To revert the changes, run the script with the
-rflag:
sudo ./amdgpu-undervolt.sh -r
Note: The /sys/class/drm/card0/device/pp_od_clk_voltage file may not exist on your system, as it depends on the kernel version and drivers. The provided script uses a different approach to access the required file.
After following these steps, your AMD GPU should be undervolted, improving power consumption and potentially reducing temperatures.
