[solved] CPU max base freq

Hi

I've discovered that my processor is not running at optimal settings. Its maximum base frequency is 2.2GHz, but it's somehow capped at 1.7GHz. I can't find where this limit is set. Interestingly, after disconnecting and reconnecting the power supply, it briefly runs correctly before dropping back down to 1.7GHz. Where should I look for a solution?

on AC

analyzing CPU 10:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 10
  CPUs which need to have their frequency coordinated by software: 10
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 800 MHz - 1.70 GHz
  available cpufreq governors: performance powersave
  current policy: frequency should be within 800 MHz and 1.70 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
  current CPU frequency: Unable to call hardware
  current CPU frequency: 1.70 GHz (asserted by call to kernel)
  boost state support:
    Supported: yes
    Active: yes

disconnecting and reconnecting

analyzing CPU 9:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 9
  CPUs which need to have their frequency coordinated by software: 9
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 800 MHz - 2.20 GHz
  available cpufreq governors: performance powersave
  current policy: frequency should be within 800 MHz and 2.20 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
  current CPU frequency: Unable to call hardware
  current CPU frequency: 1.84 GHz (asserted by call to kernel)
  boost state support:
    Supported: yes
    Active: yes

What is printed to the journal when the maximum changes?

journalctl -fm

shows nothing...

Perhaps check the firmware ("BIOS") settings?

I think I found the reason. throttled is responsible for lowering the clock speed. But I don't know why it's doing it on power plugged.
