I just installed the new F3 BIOS on my UD7 B3 board updating from F3h. The new install gave me the infinite loop on start up but clearing the CMOS fixed that.

I am trying to find the best Vcore/LLC setting with the new LLC levels.

With BIOS F3h LLC Level 1

I had 1.480 set in BIOS for 47X.
This gave me 1.464 idle and 1.428 load (using HWiNFO)

With BIOS F3 LLC Level 6

I have 1.460 set in BIOS for 47X.
I get mostly 1.464 idle with 1.476 sometimes and 1.428 load and 1.440 sometimes.

Does this look good or would you recommend I try any other settings. It seems P95 stable so far. I am testing now but only for just over 2 hours so far. I think what I am trying to understand is which setting is best and why. For example, I could use a higher Vcore set in BIOS with a lower LLC setting or a lower Vcore with a higher LLC setting. Is one preferable over the other as long as I am getting the desired voltage I need for stability which is about 1.428 on load. What if I could get 1.428 on load and idle. Would that be better yet since it seems unnecessary to have more voltage on idle than on load or am I misunderstanding something. I am relatively new to overclocking.

Oddly, (at least I think it is odd), on my UD7 B2 revision board this same CPU needed less Vcore. I had 1.460 set in BIOS and would get 1.452 idle and 1.416 load. This was 24 hour P95 stable. But with the new B3 revision board it was not stable until I increased Vcore to 1.480 (both LLC Level 1 and all other settings the same). I realize every board is different but I am trying to understand why the CPU would need so much more Vcore. I thought the board didn’t matter much in overclocking these chips. Can anyone explain what the difference might be between the 2 boards. Or is that considered a small difference that should be expected going from one board to another.

Thanks, Kent
