First time using crossfire.

Test each gpu and they are both work.

Turned on crossfire in CCC
Have 1 crossfire bridge connecting the two cards
Changed slots to x16 and x4 in bios (that the max my second slot can do.)

ASUS p8z67-v le
2 x 7950 xfx dd

Only the first gpu works in heaven. What am I doing wrong?
 
Did you install crossfire profiles? As for bios, I didn't do anything when I ran it.
 
Are you running windowed for fullscreen?

Crossfire only works in fullscreen

windowed. :D

Did not know that. Glad it is something simple. I was running the extreme heaven 4.0 bench which is set to window by default.

No. What kind of profiles do I need to install?



Everything looks good except for

"A Crossfire-capable motherboard with two PCI-express x16 or x8 lanes"

Does it have top be x8 lanes? My second one maxes at x4, but i've seen other people use an x16 and x4 setup.

Install the profiles at the bottom of the AMD driver page.
 
If using 13.1 or 13.3 CAP is included. This driver version includes its own Catalyst Application Profile or CAP, so no need for installing one separately.
