EZ GPU Control

A WIP tool for managing GPU OCs, which can automatically change GPU OCs depending on what programs are running.

Eg:

• I want max power target when running a game
• I want 70% power target when running BOINC
• Otherwise, use default power target

This is currently NVIDIA-only.

Usage

Download the most recent gpucontrol.zip file from this repo's Releases section. Extract the entire ZIP file.

Run the app and accept its terms. The main window will allow you to add profiles which specify OC settings. Profiles can optionally define 1 or more setting(s) on a per-GPU basis. After adding at least 1 profile, you can add a policy which will be applied when the configured programs are running. If multiple policies are active, the OCs will be merged in reverse order, eg the top-most policy will have priority. The profiles within a policy are merged with the same logic.

When running, the app will have an icon in the system tray. Right-click this for various settings, such as run-on-startup and changing the OC mode (policies-based, specific policy, specific profile).

Hover over the tray icon for info on the OC settings currently being applied.

Known Issues

• Window controls may flicker when the UI refreshes
• Minimize-on-start may not fully minimize the window

Any other bugs should be reported as an Issue on this GitHub repository. If the app is crashing, include the contents of log.txt.

Limitations

These features are not offered:

• VF curves - These are currently unsupported by NvAPIWrapper
• Fan curves - I don't want to bother with a curve editor
• Voltage offsets (%) - These seem to be placebo

Testing has only been done on 3000-series cards.

The impl. details for NVIDIA are handled by NvAPIWrapper. Adding support for AMD GPUs should only require appropriate changes to the GPUControl.Lib package, namely static methods in IGpuWrapper. I tried AMD's ADLX but ran into a snag preventing me from using it. ADL should work, just don't have the patience to write a wrapper right now.

TODOs

• Basic enumeration of GPUs + realtime display
• Overclocking profile config page
• Ability to apply per-GPU overclocking profiles
• Ability to configure overclocking profile for more than 1 GPU
• Ability to apply multi-GPU overclocking profiles
• Ability to set an OC profile depending on running processes
• Ability to compose OC profiles depending on use of multiple processes
• Add copy of LGPL license to release files for NvAPIWrapper
• Add more details to GPU status view for identifying multiple GPUs
• Toggle to run on startup
• Buttons for controlling policy service
• System tray entry for starting/stopping the policy service
• General UI improvements
• GPU impl. abstraction
• Fan control (not properly tested)
• Support for temperature limits in policies
• Proper error handling, etc. (bare basics are handled)
