vcore

Hello, My PC is only a few weeks old (there are no old components in it) and I have recently found the CPU requesting too much voltage, and it being supplied with too much (as per AMD specification for the 5000 series). Which measurement is more accurate? I should note, that this is with PBO...

I am asking to learn what's the difference between "core VID" and "Vcore" because i think they are the same since they both show the voltage of the core but the readings are different so i need to know what's the difference. Thanks!
