可以控制几个频率,达到类似的效果。soc/fclk/lclk/gfx频率都可以单独控制。
- $./ryzenadj -h
- Usage: ryzenadj [options]
- Ryzen Power Management adjust tool.
- -h, --help show this help message and exit
- Options
- -i, --info Show information and most importand power metrics after adjustment
- --dump-table Show whole power metric table before and after adjustment
- Settings
- -a, --stapm-limit=<u32> Sustained Power Limit - STAPM LIMIT (mW)
- -b, --fast-limit=<u32> Actual Power Limit - PPT LIMIT FAST (mW)
- -c, --slow-limit=<u32> Average Power Limit - PPT LIMIT SLOW (mW)
- -d, --slow-time=<u32> Slow PPT Constant Time (s)
- -e, --stapm-time=<u32> STAPM constant time (s)
- -f, --tctl-temp=<u32> Tctl Temperature Limit (degree C)
- -g, --vrm-current=<u32> VRM Current Limit - TDC LIMIT VDD (mA)
- -j, --vrmsoc-current=<u32> VRM SoC Current Limit - TDC LIMIT SoC (mA)
- -k, --vrmmax-current=<u32> VRM Maximum Current Limit - EDC LIMIT VDD (mA)
- -l, --vrmsocmax-current=<u32> VRM SoC Maximum Current Limit - EDC LIMIT SoC (mA)
- -m, --psi0-current=<u32> PSI0 VDD Current Limit (mA)
- -n, --psi0soc-current=<u32> PSI0 SoC Current Limit (mA)
- -o, --max-socclk-frequency=<u32> Maximum SoC Clock Frequency (MHz)
- -p, --min-socclk-frequency=<u32> Minimum SoC Clock Frequency (MHz)
- -q, --max-fclk-frequency=<u32> Maximum Transmission (CPU-GPU) Frequency (MHz)
- -r, --min-fclk-frequency=<u32> Minimum Transmission (CPU-GPU) Frequency (MHz)
- -s, --max-vcn=<u32> Maximum Video Core Next (VCE - Video Coding Engine) (MHz)
- -t, --min-vcn=<u32> Minimum Video Core Next (VCE - Video Coding Engine) (MHz)
- -u, --max-lclk=<u32> Maximum Data Launch Clock (MHz)
- -v, --min-lclk=<u32> Minimum Data Launch Clock (MHz)
- -w, --max-gfxclk=<u32> Maximum GFX Clock (MHz)
- -x, --min-gfxclk=<u32> Minimum GFX Clock (MHz)
- -y, --prochot-deassertion-ramp=<u32> Ramp Time After Prochot is Deasserted: limit power based on value, higher values does apply tighter limits after prochot is over
- --apu-skin-temp=<u32> APU Skin Temperature Limit - STT LIMIT APU (degree C)
- --dgpu-skin-temp=<u32> dGPU Skin Temperature Limit - STT LIMIT dGPU (degree C)
