i really think its the board (dfi nf3 754) It has already killed 3 gigs of ram just by turning it off, i think I need to pick me up another one. It killed my good gig of ch-5, my good gig of twinmos utt so im not gonna risk too much with this ram, im sure its better than the board will let it be. I stuck my gskill in it last night and now it will only work in this board and not my msi while it was doing 300 @ 2.5,3,3,7 like it was nothin in my msi.
