im using two sets of corsair dominator 1066 (2x2gig). the version numbers are the same. I'm not sure if it's the motherboard because any combination of two sticks in any two slots will boot and run fine. It seems like no matter what combination of settings I use, the second I populate another slot, the whole system turns into a vegetable and hangs at det_dram, no signal on screen, video card fan running 100%, etc. If someone can tell me for sure it's the motherboard, then i'll just return this set of ram and stick with 4 gigs because it's not worth it for me to go through the hassle. But so far, I have been unable to boot with any settings. I am stumped.
