[der8auer] Per CCX overclocking
RYZEN 3000 OC per CCX rather than all-core
Update: Extreme Caution - doesn't seem worth risking your CPU over 200 or 300 MHz

It is a CPU killer if the VRM controller is running in offset-mode.
I tried it with the voltage mode set to offset (or "Auto") and setting 4200MHz for CCX0/1 and 4050MHz for CCX2/3 resulted in 1.405V actual Vout during Cinebench R20.
The voltages during the default OC-Mode remain sane, regardless of the VRM controller operating mode.
This hack however causes the voltage governor to go insane.
I have no idea why someone thought it would be a good idea to release this to the public...
updated with AthyraE resuts over at reddit [Dphotog for pointing it out]
4 CCXs stable at 4525, 4500, 4350, and 4325 MHz at 1.38V
CINEBENCH R15 and R20 results @ 4.3GHz vs per CCX OC
