problem with XFX 7950 GX2 XXX

menko2

hi.

i´m alberto. i´m a owner of a new xfx 7950 gx2 xxx. i have an asus a8n-sli deluxe nforce4 (it´s not in the list of graphic cards supported but it´s sli and nforce4).

when i received the card, it looked that it was working good. now, i don´t know why, i´t´s going much slower. i think that maybe it´s using only one gpu.

i passed the 3dmarks and games and bedore were good, now it´s much slower.

i installed the 91.31 driver and latest bios of my motherboard (1016).

i also played with the forceware control panel in the original and new mode.

in the new mode of control panel i can see the " multi gpu performance mode" and i tried all of them. 2 of the modes crash the computer sometimes.

what can it be the problem????

thank you
