Another happy (for now... ) Extreme4 user here.

I'm using the latest 1.70 bios from asrock site. I did some minor adjustments in the UEFI:

2500k @ 45x w/ fixed 1.275v set in bios, PLL ov off, Turbo on, all power savings/C-states on, LLC at lv2, all other volts settings manually set but pretty much default.

Everything looks OK, temps are great but one thing is bugging me. UEFI/CPU-Z/HWmonitor/etc. all read the vcore as expected with given settings at idle and load.

But using Real Temp 3.67, whenever I launch some stress test, be it Prime95, Linx, OCCT the VID reading goes from ~1.22v at idle to 1.366v at full load! No other SW reading does that, they all stay at ~1.27v. I know SW readings are not fully accurate but that Real Temp load VID reading is really bugging me. I don't know for sure if I'm stable at 1.275v or 1.366v...

I read this thread from start to finish, searched the Real Temp thread but found nothing like what I'm getting here.

Any ideas?
