I've played around a bit more. Still at 4.7 but vcore dialed down to 1.20. Completely stable, 12 hours + of OCCT. With my current cooler, temp spikes top out at 62C across any given cores but tend to sit in mid 50's the majority of the bench.
At this point, I could crank it higher easily enough but not sure what the value would be. 4.7ghz for day to day use is plenty. My average usage temps are in the high 30's to low 40's, fans barely ramp up.
Under load the vcore actually drops at times to 1.18 but never exceeds 1.2
Anyone know what the IA AC/IA DC does? Default seems to set it to 0 for both.
So i set both to 1. Blue screens everywhere.
It's for internal LLC setting, I believe when i originally had to mess with it on a super micro board, it has values from 0-12000, measured in ohms, and i assume it determines the slope of the LLC curve. i did a write up somewhere on it. I wouldn't mess with it.0 must default to the menu option for internal LLC.
The BIOS puts a constant load on the CPU, CPUz is reporting ups and downs due to load.
Even GBT says to set Turbo and even Extreme (although I saw Turbo was the highest, I think they might have removed extreme) in their 5GHz guide. Does it drop down under load to 1.262 and at idle at 1.284?
Extreme is still available in the latest BIOS. It is what got my 8700k stable at 5.1 ghz at 1.32 vcore.
