UnOfficial Asus Rampage II Extreme Thread

I followed these guidelines and mine passed with colors at 4GHz but with 20x multi. I am also cool to get 4.2 but I wanna find the lowest combo of temps v/s voltages for daily 4GHz. See below, in BOLD is what I changed or picked.

Now I am curious about the PLL left at lowest. Is it not benifitial anymore to slightly increase this as in X48 w/ core 2 quads? I had mine at 1 level from up from lowest for the longest time stable but moved it down for testing.

Loadline calibration: I had always used in all my ROG mobos sice X38 Maximus. It has and still helps to keep vcore (for my uses) in target but if anything the vdrop will then happen innlow use, not the other way around.

votages? What is a realistic decrease for my i7 920 (DO) if I only need 4GHz 20x200? Can I lower QPI any less w/ stabilty you think or this safe range if temps are good, or is this more to do with DRAM and BCLK? Can I effectively lower my NB/SB core volts then if bk down to 20x200?

Otherwise, it ran good so far. Temps are hitting average loaded in Prime of upto 72c 1/2 & 68c 3/4. Is this normal for a noticable differance between 1/2 & 3/4 core temps? in idle they are cores 1/2= 39c, 3/4= 34c
