RyzenAdj

Adjust power management settings for Ryzen Processors.

Thanks a lot to "JustSkill" for his Amazing GUI interface!

Also, you can choose le.storm1er/ryzen-controller as a alternative GUI interface.

Usage

The command line interface is identical on both Windows and Unix-Like OS.

You should run it with Administrator on Windows or root on Linux.

You can write a shell script or bat to do it automaticly.

$./ryzenadj -h
Usage: ryzenadj [options] [[--] args]
   or: ryzenadj [options]

 Ryzen Power Management adjust tool.

demo

If I'm going to set all the Power Limit to 45W, and Tctl to 90 ℃, then the command line should be:

./ryzenadj --stapm-limit=45000 --fast-limit=45000 --slow-limit=45000 --tctl-temp=90

Build

Build Requirements

Building this tool requires C & C++ compilers as well as cmake. It requires privileged access to NB PCI config space, in order to compile it one must have pcilib library & headers available.

Linux

Please make sure that you have libpci dependency before compiling. On Debian-based distros this is covered by installing pcilib-dev package:

sudo apt install libpci-dev

The simplest way to build it:

cmake CMakeLists.txt
make

Windows

It can be built by Visual Studio automaticly. However, as for now, MingW can't be used to compile for some reason.

Required dll is included in ./prebuilt of source tree. Please put the dll library and sys driver in the same folder with ryzenadj.exe.

TODO

Determine the unit of time
Add more options
Code cleanup (The original program was written in C but now it's C++ in order to call VC++ library)
