" rel="nofollow - Hello -)

So, i have that motherboard with an i5 8600k.

With all stock/default values (Multi core enhancement OFF also) i get 1.168v in BIOS readings, but in windows with ATuning and with HWinfo i get readings of 1.30v..this is really high for default value btw, i can lower it by -100mv with no problem at all.

But what i want to know is, why this difference in voltage readings? Other motherboards i had applied max voltages when entering bios, is ASRock different in that aspect? Or is something wrong?

The other question i have is, in BIOS, under OC Tweaker/CPU, whats is the difference of choosing MHZ "Per Core" or "Specific Per Core" ?
