MEG Z390 ACE - Ignoring Manual set voltages!
As the title, spent a few days getting a stable overclock, stress testing etc. was really happy with it.
Then, last night, noticed 'system' temp was really high. Is normally ~30c regardless of CPU load but it was sitting at 50c!
Worried, I fired up HWinfo64 and some some scary voltages.
I'd set static in the BIOS:
but in HWinfo i was seeing:
VCCIO: can't remember
VCCSA: can't remember
Worried I was about to melt the PCH, i rebooted to the BIOS, and sure enough, it was showing these voltages. Loaded factory defaults, rebooted and the voltages remained stuck there. Did a CMOS clear, and that finally reset them back to standard levels.
What happened here? If I hadn't noticed, I could have potentially killed the board!
As per the attached image, should I be locking down any other the other voltages that I've left on auto?
Why the hell would the system set PCH to a voltage that high?! I mean, it's only another ~100mV but still, raised temps 20c so obviously not a good thing.
