how to dissable CrossfireX?

post #1 of 11
Thread Starter 
Im curious because every game that ive played so far runs worse than 1 8800GTS 320mb

So like for say. when i run fear @ 1680X1050 maxed with SLI 8800GTS 320s I get 30FPS

With 1x HD 3870 Maxes i get 22FPS

When I disable SLI i get 70FPS..

So how do i get the 3870X2 to not use both chips on the GPU?? Is there anyway to do this. If not Im gonna throw this card against the wall because its begining to piss me off.

Try Catalyst Control Center (updated to newest version), if not, I'm afraid you can't...

Not sure how to disable that, under ATI Overdrive in the newest catalyst drivers there is selection for Crossfire X, with a checkbox. Not sure what happens with just on 1 card (2 GPUs), but I have it checked with twin 3870 x2's (quad GPU). I am using amd gpu clock utility in a bat file to fix the core/memory, and that seems to have helped a TON in crysis. Every other game just gets laughed at by these cards (IE - COD4 @ 1680x1050 w/everything turned up).

you can't disable the 2nd gpu on the hd3870x2. Not sure whats happening in fear as it should not be demanding at all for crossfirex.


I can try fear tomorrow after work and see if I can help. Don't have time now as it's nearly 3AM EST and I work bright and early! =o)

I ran FEAR today, ~160fps single X2, 180fps CFX with 600+fps peak.

Sublime IDK what to tell you bro, my X2 will destroy every game except Crysis.

Interesting.... My X2 gets destroyed in every game but crysis. Except for on XP then crysis actualy runs. Im reinstalling it again hoping it will work.

WIth this HD 3870x2 card crysis closes whenever it wants.
