VID is 1.375 and BIOS is set to 1.375 but it idles at 1.368 and bounces between 1.380 and 1.392 under load. If I set my LLC any lower then it drops below 1.368 under load. If I set LLC any higher then it will hit over 1.400 under load.
My temps were still slightly on the incline when I took this, but this is under load.
That's great. It looks like that H40 is really working, but still holding it's own. Does that HWinfo program show Core Temps as well? I believe the one listed in that screen shot is the CPU Socket Temp.
I'm also curious if your stock vCore @ 3.5Ghz is 1.375 with Turbo Disabled? That seems kind of high for an 8320. It could also be bouncing around if it's still set to Auto, instead of manually inputting the voltage after a restart.

Thank you very much.

Sabertooth, Custom Water, recipe for success
A couple notes:
If two cores within the same module fail during Prime95, that module may be limited in it's ability to Overclock further. Sometimes more voltage helps, but usually not.
If only a single core fails, then more voltage will fix it, but sometimes it takes too much extra voltage.
My CPU can almost run Prime95 Stable at 4.5Ghz with only 1.325v, but Core 8 will fail. I need 1.3625v to keep Core 8 happy. The amount keeps increasing the higher I go. I'd need to disable Module 4 (cores 7-8) to hit 5.0Ghz stable.
**Not all the CPU's have that issue, or as severe.
