Why my abit NF7-S 2.0 cannot prime95 with 2 sticks of 512mb CH5 rams
i can prime with 1 stick of 512mb twinmos CH5

but once i chuck in another stick, it fails prime95 in less then 30mins
the ram i buy as in dual channel pack






i tried increasing voltages to cpu, ram and vdd
tried using latest bios
tried changing slots
tried playing with ram timings, used 7 3 3 2.5, 8 3 3 2.5, 11 3 2 2.0, 5 3 3 2.5

bios settings
mem:cpu ratio 6:6
fsb 200
multiplier 10
it still gives me error no matter wat

rams passes memtest86 with 1 or 2 sticks together

have you tryed a dif multi. My never ran stable at 10x before.

As for Prime 95 failing, im dont know there never used it

AFAIK there is a known issue running dual channel and using 10x or 10.5x

It is extremely unstable in this setup. However Tic-tac fixed this and there is a thread about it in the Abit forums.

Check it out! It worked for me.

already using that bios, still fail

still dun work, reinstalled windows and prime95 version 23, still prime95 error

tried running them on slot 1 & 2(single channel) and still error

winbond CH5 are in nvidia compatibility list =(

Try putting your comments together in one post instead of 4 otherwise it may smack of spamming. Anyway have you tried what the others suggest and use a different multi (a lower one but the same FSB to rule that out as an issue).
