I noticed that cpu frequency never go above 3.8GHz that is very low with my 9700x processor.
My amd_pstate=acticve and governor set to performance

“cpupower frequency-info” shows next:
driver: amd-pstate-epp
CPUs which run at the same hardware frequency: 2
CPUs which need to have their frequency coordinated by software: 2
maximum transition latency: Cannot determine or is not supported.
hardware limits: 600 MHz - 3.8 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 600 MHz and 3.8 GHz.
The governor “performance” may decide which speed to use
within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 3.74 GHz (asserted by call to kernel)
boost state support:
Supported: yes
Active: no
AMD PSTATE Highest Performance: 166. Maximum Frequency: 5.58 GHz.
AMD PSTATE Nominal Performance: 113. Nominal Frequency: 3.80 GHz.
AMD PSTATE Lowest Non-linear Performance: 89. Lowest Non-linear Frequency: 2.99 GHz.
AMD PSTATE Lowest Performance: 18. Lowest Frequency: 600 MHz.
I believe that default behavior should not be like this!
But ok i read this article General System Tweaks | CachyOS
run: echo 1 | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/boost
and now boost us enabled and frequency can reach 5.5 GHz. But only until reboot.
Question Is there a normal way to do this permanently? Without creating services?
