My original plan had been to install 3800X Set PBO etc and leave it well alone. The only reason I have for fiddling at all is because I saw consistent voltages right up to 1.5v and it just didn't 'feel' right.
More or less this is false thinking or feeling...
This is how ZEN2 is working and programmed by AMD. It is said alot of times that high voltage for low clock/load and eventually low power current (EDC/Ampere) does not hurting anything (PPT/Watt stays low). These chips have internal monitoring and regulation for clock/voltage in conjunction with temperature to preserve performance and longevity of silicon. Its called FIT (silicon FITness controller).
If you have it on auto for PB and PBO and increase cooling, clocks will go up for allcore loads and it will sustain the rated single core boost more (effective clock goes up on all scenarios).
Additionally If you keep power current tamed while keeping it cool clock increasing further and its more sustained.
