good idea this vault Sen.
for those with 2X512 in dual channel, try one of the merlin's bios that has "Fire" in it, i think it has potential...

2X512 CorsairXLPro (not sure if it has samsung chips or not, haven't removed the heatspreaders), in dual channel (slots 1&2 - the farthest from the cpu)

edit:
the m/b is the one with blue slots
Sen, i think it might be a good idea to separate the results by memory modules size as well. a bios that works miracles with, say 2x256, could do nothing or even drop fsb for 2x512. single channel 512 is a different story altogether... believe me, i've tested plenty of them
