OverdriveNTool is a lightweight Windows utility designed for advanced tweaking of AMD graphics cards. The program allows users to edit GPU parameters through the OverdriveN and Overdrive8 APIs on a wide range of older Radeon cards, including the R9 290/390 series, Fury lineup, Vega 56/64, Radeon VII, and RX 5000 series.
Key features include fan curve customization, memory timing adjustments, profile management, and the ability to apply or reset settings across all supported GPUs at once. It also offers basic command-line support for automation.
The latest version, 0.2.9, was released in early 2021 and remains available as a free open-source tool on SourceForge.
