RyzenAdj is a command-line utility for changing power-management parameters on AMD Ryzen mobile processors and APUs. It provides direct access to limits and controls exposed through the processor’s System Management Unit, making it useful for tuning power consumption, thermals and performance.
On Linux, RyzenAdj requires elevated privileges to reach the relevant hardware interfaces. It can use the ryzen_smu kernel module and can fall back to direct memory access where that route is available. Settings are applied through command-line arguments, which also makes the utility suitable for shell scripts and other automation.
This is free and open source software.
Key Features
- Set sustained, fast and slow package power limits.
- Adjust the processor temperature limit and several skin-temperature-related limits.
- Configure VRM and SoC current limits, including TDC and EDC controls.
- Set minimum and maximum SoC, fabric, video and graphics clock frequencies where supported.
- Expose power-saving and maximum-performance controls whose exact behaviour depends on the processor generation and platform.
- Display important power metrics after applying settings.
- Dump a wider table of available power metrics for inspection.
- Use the same general command-line workflow on Linux and Windows.
- Apply settings repeatedly from shell scripts when firmware or other power-management components overwrite them.
- Support a broad range of Ryzen mobile processor families, subject to platform and firmware capabilities.
- Apply values immediately without requiring a persistent background daemon.
- Expose separate controls for CPU, SoC, graphics and other APU domains when the processor firmware provides them.
- Use command-line output to verify applied values and inspect whether the platform accepts requested limits.
