hey I have 11.5 cata
2 6990s crossfired
and phoenix 1.48
for some reason every couple of hours, the 3 of the 4 gpus just stop running and only one still runs at 333 m/hash
the other three look frozen, but the computer is not frozen.
its very cool in my basement, and i checked all the power cables again. anyone know whats happening?
I have another setup with also two 6990s. everything is same except the brand of the video cards but that shouldnt matter right?
my other setup works beautifully.
