How do you stress test these CPU's, because I find it very difficult to see what is stable other than just doing regular work.
I can 100% state that IntelBurnTest 20x Maximum doesn't cut it.
Examples:
46x100 1.270V LLC Auto (1.248-1.264), which is the same as Ultra High , IBT 20x max stable, but not stable listening to Winamp or playing Dead Space, requires 1.290V to be 24/7 stable
46x100 1.250V LLC Extreme (1.248-1.264V), IBT 20x max stable, BSOD in idle, didn't test how much it really needs, probably 1.260V
46x100 -0.015V LLC Auto (1.240-1.256V), IBT 20x max stable, already got BSOD in idle
48x100 +0.045V LLC Auto (1.296-1.328), IBT 20x max stable, BSOD 0x00000124 while watching movie
But here are my estimates to what would be stable in my experience:
Offset voltage LLC Auto
2x IBT max OK, up by 0.02V to be 100% stable
20x IBT max OK, up by 0.01V to be 100% stable
Manual voltage LLC Auto
5x IBT max OK, up by 0.03V to be 100% stable (46x100 1.260V required 1.290V, and 48x100 1.320V required 1.350V)
20x IBT max OK, up by 0.02V to be 100% stable
But of course some better stress testing program would be better.
About BSOD, I always get 0x00000124, which would suggest that if you get this, you must up the vcore.
BIOS/CPU-Z voltage findings
1.290V set in BIOS
Auto: 1.264-1.280
High: 1.232-1.248
Ultra High: 1.264-1.280
Extreme: 1.288-1.304
Voltage also get higher for short period of time, these are just the voltages that stay on longest, usually the difference between lowest and highest is 0.016V.
