I have an i7-9750h and recently read the FAQ that when undervolting you need to set the amount of mV of the core and cache to be the same value. I have the core set to -150mV and cache -125mV and it's stable, however when I set both to -150mV it crashed. 
1) Should I just keep the first stable value or should I tweak the core to -125mV also?
2) What happens if the core and cache not in the same value?

    Hi, there is no problem both to have different voltages and as long it is stable you can leave it like that with no worries whatsoever. However if you wanna play with it you can try to push as low as you can on both.
