so i've got an issue, my 2 gig kit came back from rma today and all for 1 gig sticks work now but here is the problem. The memory is ddr2 1150 @5,5,5,12 2t stock. with only 2 sticks in i can do this but with 4 i cannot. In fact i'm only getting about 960Mhz @5,5,5,12 2t with all 4 sticks in. Now i'd like to run vista x64. am i better off with 32 bit windows @1150 with only 2 gigs or am i better off with vista x64 with 4gigs at 960mhz??
