RyzenAdj

Adjust power management settings for Ryzen Mobile Processors.

Build Status

Based on: FlyGoat/ryzen_nb_smu

RyzenAdjUI_WPF by "JustSkill" is no longer maintained, for GUI please see Universal x86 Tuning Utility or ryzen-controller-team/ryzen-controller.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 automatically.

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

Demo

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

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

Documentation

Installation

You don't need to install RyzenAdj because it does not need configuration, everything is set via arguments However, some settings could get overwritten by power management features of your device, and you need to regularly set your values again.

We did provide some examples for automation. And these require configuration during installation.

Linux Installation

Because it is very easy to build the latest version of RyzenAdj on Linux, we don't provide precompiled packages for distributions. Just follow the build instructions below and you are ready to use it.

Windows Installation

Before you start installing anything, it is highly recommended getting familiar with RyzenAdj to find out what can be done on your device. Use the CLI ryzenadj.exe to test the support of your device and to benchmark the effects of each setting. If your values don't stay persistent you may want to consider installing our example script for automation.

  1. Prepare your favorite RyzenAdj arguments
  2. Copy the content of your RyzenAdj folder to the final destination
  3. Put your configuration into readjustService.ps1 and test it as administrator until everything works as expected
  4. Install readjustService.ps1 as Task for Windows Task Scheduler by running installServiceTask.bat

Deinstallation of the Task can be done via uninstallServiceTask.bat

Over Windows Task Scheduler you can check if it is running. It is called RyzenAdj below AMD folder. Or just run

SCHTASKS /query /TN "AMD\RyzenAdj"

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 build-essential cmake libpci-dev

On Fedora:

sudo dnf install cmake gcc-c++ pciutils-devel

If your Distribution is not supported, try finding the packages or use Distrobox or Toolbox instead.

The simplest way to build it:

git clone https://github.com/FlyGoat/RyzenAdj.git
cd RyzenAdj
rm -r win32
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make
if [ -d ~/.local/bin ]; then ln -s ryzenadj ~/.local/bin/ryzenadj && echo "symlinked to ~/.local/bin/ryzenadj"; fi
if [ -d ~/.bin ]; then ln -s ryzenadj ~/.bin/ryzenadj && echo "symlinked to ~/.bin/ryzenadj"; fi

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 ./win32 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.
