" rel="nofollow - I have an I5-8600k CPU with a CORSAIR AX860 psu

Why my motherboard undervoltages the CPU having all the options stock - default - Auto ?
I get 1.08 volts at BIOS and 1.08-1.05 while testing with Prime95. @ 4.1ghz (AVX limiter i think)
I am asking this because i get random lock ups and freezing in windows and in games and then i have to hard reboot the PC through my PSU button e.t.c.

I just put the vcore manually @ +50mv and level3 LLC instead of Level 5 to get 1.2 volts at prime95

" rel="nofollow - Differant CPU of same type require differant core volts, but 1.08v under load DOES seem too low. It should climb to about 1.32v under heavy load. What utility are you using to read the core volts ?
I suggest HWmonitor by CPUID and never run more than one temp reading utility or it can cause issues !
