I'm not sure if Crossfire is working

post #1 of 5
Thread Starter 
When I go to CCC the crossfire option is already checked. The 4850s that show up are both the ASUS HD 4850, but I have one from ASUS and another from Visiontek. Does it just read both of them as 'from ASUS' since I'm connected to the ASUS 4850?

If your ASUS card is considered the main one, it's probably the way windows sees like so. You should be able to CF between diffrent brands without any issues, and in some cases, diffrent models (within the same series 4k with 4k, 3k with 3k, etc)

You can use GPU-Z to check if both cards are there and run 3DMark06 benchmark test. The score should be higher.

I got both of mine installed this morning. Like Me_XMan said try using gpu-z and it should say crossfire enabled. My 3dmark score only went from 12k to 13k at first. I had to oc my cpu to go any higher. I currently have my quad at 3.0 until i get more comfortable with the DFI bios but my cards still appear to be cpu limited even with the quad at 3.0 so keep that in mind if your scores don't change much.
