Max Boost Clock Override not recognized in Corefreq (Zen3/Vermeer)

[gel-crabs]

Hi again, in the PBO2 menu in the BIOS there is Max Boost Clock Override, which allows you to overclock. However, changing the boost clock override is not recognized by CoreFreq; the max frequency does not change. Need some debug info?

(Ryzen 5 5600X)

I just know the Register to read CPB ratios

I can however write non boosted P-states Max, 1C and 2C

1C and 2C

1. Turbo Boost CPB must disabled
   
2. Select Ratio
   
3. Alter the whole Processor
   
   
4. CPB can now be reactivated
   

Max (non-boosted) frequency

1. Need a non TSC clock source
   HPET is fine
   
2. Turbo Boost CPB must disabled
3. Select a new frequency ratio
   
   Check kernel log for any instability: kernel TSC clock source may be lost.
   You can switch to CoreFreq TSC which is aware about what you are doing.
