Adjust power management settings for Mobile Raven Ridge Ryzen Processors
Adjust power management settings for Ryzen Processors.
Based on: FlyGoat/ryzennbsmu
RyzenAdjUI_WPF by "JustSkill" is no longer maintained, for GUI please see le.storm1er/ryzen-controller.
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.)
Settings -a, --stapm-limit= Sustained power limit (mW) -b, --fast-limit= Fast PPT power limit (mW) -c, --slow-limit= Slow PPT power limit (mW) -d, --slow-time= Slow PPT constant time (S) -e, --stapm-time= STAPM constant time (S) -f, --tctl-temp= Tctl temperature (▒? -g, --vrm-current= VRM Current Limit (mA) -j, --vrmsoc-current= VRM SoC Current Limit (mA) -k, --vrmmax-current= VRM Maximum Current Limit (mA) -l, --vrmsocmax-current= VRM SoC Maximum Current Limit (mA) -m, --psi0-current= PSI0 Current Limit (mA) -n, --psi0soc-current= PSI0 SoC Current Limit (mA) -o, --max-socclk-frequency= Maximum SoC Clock Frequency (MHz) -p, --min-socclk-frequency= Minimum SoC Clock Frequency (MHz) -q, --max-fclk-frequency= Maximum Transmission (CPU-GPU) Frequency (MHz) -r, --min-fclk-frequency= Minimum Transmission (CPU-GPU) Frequency (MHz) -s, --max-vcn= Maximum Video Core Next (VCE - Video Coding Engine) (Value) -t, --min-vcn= Minimum Video Core Next (VCE - Video Coding Engine) (Value) -u, --max-lclk= Maximum Data Launch Clock (Value) -v, --min-lclk= Minimum Data Launch Clock (Value) -w, --max-gfxclk= Maximum GFX Clock (Value) -x, --min-gfxclk= Minimum GFX Clock (Value) -y, --prochot-deassertion-ramp= Time to ramp clocks after PROCHOT is deasserted (ms)
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
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.
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
sudo dnf install pciutils-devel
The simplest way to build it:
mkdir build && cd build cmake .. make
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.
