Hi,
i got 5970*2, and started at 6000-6400 m.hashes/s, but after a while, gpu 0 and 1's speed decrease to 400 and 800 m.hashes/s. i tried both win7 32bit and 64bit with different driver already. but it still got same thing....
Is that normal? or is there something wrong with one of my card?
plz help.
thx......
