## What it is
RyzenAdj is a command-line tool for adjusting power management settings on AMD Ryzen mobile processors (APUs), including STAPM/PPT power limits, temperature limits, current limits, and clock frequencies. It works identically on Windows and Linux by communicating with the Ryzen System Management Unit.

## Use cases
- limit CPU power draw on a Ryzen laptop to extend battery life
- raise the sustained power limit (STAPM) of a Ryzen APU for better performance
- set a custom Tctl temperature limit for a Ryzen mobile chip
- adjust VRM current limits on a mini PC with a Ryzen APU
- script power profile switching between battery and plugged-in modes
- tune GFX and SoC clock frequency ranges on a handheld gaming PC

## When to choose
- you need fine-grained control over Ryzen APU power and thermal limits from the command line
- you want to automate power tuning via scripts on Windows or Linux
- you are configuring a Ryzen-based handheld, mini PC, or laptop

## When to avoid
- you have an Intel processor or a desktop Ryzen CPU without supported SMU registers
- you prefer a graphical interface for tuning
- your system firmware or kernel does not allow the required low-level access
