Linux AMDGPU Control Application

This application allows you to control your AMD GPU on a Linux system.

Current features:

• Viewing information about the GPU
• Power/thermals monitoring
• Fan curve control
• Basic overclocking

Currently missing:

• Voltage control on Vega20+ GPUs
• Precise clock/voltage curve manipulation (currently can only set the maximum values)
• Multi-GPU system support Should work now
• The card model detection isn't very reliable

Installation

• Arch Linux: Install the AUR Package
• Anything else:

  • Install dependencies:

    • Ubuntu/Debian: sudo apt install cargo rustc libvulkan-dev git libgtk3-dev
    • Fedora: sudo dnf install git gtk3-devel rust cargo vulkan-headers

  • git clone https://github.com/ilyazzz/LACT && cd LACT

  • ./deploy.sh

Usage

Enable and start the service (otherwise you won't be able to change any settings):

sudo systemctl enable --now lactd

You can now use the application.

Note: By default, only members of the group wheel can change settings. This can be changed by editing /etc/lact.json and changing the group value.

CLI

There is also a cli available.

• Getting basic information:

  lact-cli info

  Example output:

  GPU Model: Radeon RX 570 Pulse 4GB
  GPU Vendor: Advanced Micro Devices, Inc. [AMD/ATI]
  Driver in use: amdgpu
  VBIOS Version: 113-1E3871U-O4C
  VRAM Size: 4096
  Link Speed: 8.0 GT/s PCIe
  

• Getting current GPU stats:

  lact-cli metrics

  Example output:

  VRAM Usage: 545/4096MiB
  Temperature: 46°C
  Fan Speed: 785/3200RPM
  GPU Clock: 783MHz
  GPU Voltage: 0.975V
  VRAM Clock: 1750MHz
  Power Usage: 38/155W
  

• Showing the current fan curve:

  lact-cli curve status

  Example output:

  Fan curve:
  20C°: 0%
  40C°: 0%
  60C°: 50%
  80C°: 88%
  100C°: 100%
