RyzenAdj

Adjust power management settings for Ryzen Processors.

Build Status

Based on: FlyGoat/ryzennbsmu

RyzenAdjUI_WPF by "JustSkill" is no longer maintained, for GUI please see le.storm1er/ryzen-controller.

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.

-h, --help                            show this help message and exit

Options -i, --info Show information (W.I.P.)

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:

mkdir build && cd build
cmake ..
make

Windows

It can be built by Visual Studio + MSVC automaticaly, or Clang + Nmake in command line. However, as for now, MingW-gcc 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.

We don't recommend you to build by yourself on Windows since the environment configuarion is very complicated. If you would like to use ryzenadj functions in your program, see libryzenadj.
