you can't compare voltages across two different chipsets...different ballgames, different sports even. keep in mind, he is also running 4x2GB which is going to require more work on the MCHs part. perhaps the reason for the high vMCH. with that said, yes, a lot of those voltages in his setup are rather high.
i take your chipset comment on board. The reason I'm sticking it back in the 790i, is that I wanted to see whether my cpu had degraded or not. I had similar results on the P5E3 Deluxe to the Rampage regarding required volts and stability. For instance 4.2 ghz at 1.42v would pass OCCT on the 790i. 4.2 on the Rampage requires 1.485 to get small FTT even going without bluescreen.

Sure thing 30h6, my comments are more questions really rather than statements. Yes I haven't really worked that much with 2 x 2GB so I can see your point. We know that 1.35v for VTT is the max safe for 45nm cpus, but still want to know about PLL?
