Heaven Benchmark and Crossfire [Fixed]

post #1 of 4
Thread Starter 
Hey guys.
I decided to test heaven benchmark with my 7850 (2gb) crossfire setup.
i have them both overclocked to 1150mhz.
when i run the benchmark i can clearly see it only uses one card (the main one is hot, the secondary is at 0 use and 30c).
i get a score of 750.

is that score good for one asus cu2 7850 2gb?
why cant i run it with both the gpus?

thanks in advance !

Is crossfire enabled in CCC? Remember, crossfire setups usually mean that you have to fight with the drivers a bit. When I first started out with CFx, I enabled it in CCC, adjusted some other settings, and then checked again to see that it had magically been disabled.

If it's on, but still not working, try checking the box to force it in all applications. Heaven does have a profile for sure, but again, fighting with drivers.

Also, make sure ULPS is disabled. It's known to cause some bizarre problems with overclocking, especially in a crossfire setup.

Create a 3d custom profile for Heaven and select crossfire mode "optimize 1x1".

i know what you are talking about, i agree.
i tried all of them and none of these worked (already had cf on and ulps off).
i did have a problem (just like you said, just a bit different) with window mode, i only had the cf working on full screen mode.
