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.
you may not be too off on your assessment of the 790i...i too have found the 790i to require less voltage for equal overclocks to other boards. it might be the 790i reporting lower volts but even when measured with a DMM, it seemed to clock higher at less voltage than other boards. my experiences are all with dual cores but it might be the same type of thing you are seeing with quads. nothing crazy but enough to notice type thing.

as for 2gb sticks, i haven't spent a lot of time with them on the RE but he is running 4x2GB which has to be the reason for the high vMCH needed. again, just an assumption based on known information from others that have. i have no need to ever run 4x1Gb let alone 4x2GB so i won't be spending any time testing any time soon to find out definitively. in my 2x2GB testing though, higher vMCH definitely helped clocks so i can only imagine 4x2GB would require even more at those types of clocks.
