So my ati hd 4850 x2 runs normally but, when i play games it freezes the game and i have to restart the comp. im sure i have the right drivers for my gpu , and i have catalyst 9.7 for windows vista ultimate x64 (not activated i don't know if activating it matters!! )
im using catalyst 9.7 for windows vista x64 i figured the problem its not the temp or something its because catalyst cc shows that i have a crossfire on ... so i disabled it and everything went good , but now only one of my 2 gpus work how can i activate both of them without using that crossfire thing ( i have one grafix card 2 gpus you propably know )
I may be completely wrong about this but I think Sapphire makes their own drivers for the 4850X2, why don't you check their site for drivers? Again if I'm wrong I hope somebody will say something but give that a try.
No guys i know am respoding late but the problem is that the MOBO does'nt support Crossfirex Technology so i can't activate the two gpus in 4850 x2 if i activate them both the games freezs ( mobo = MSI p45-8d )
Ok look when i let Catalyst cc enable crossfire the games freezs so what do ya think ?!!? if i don't enable it itll show that theres one primary gpu and one disabled gpu , and i checked if my msi p45 supports CF and i didn't find anything so if i don't solve this problem ill change to asus P5Q DELUXE for 30$ . and theres big difference in FPS when CFX is enableb for example :
COD 4 :
normal : max fps is 112
CFX mod : max 256 fps and it can reach up to 300 fps with the new catalyst drivers .
