3 video-cards installed but only 2 ...

[t29]

hi,
i don't send questions about hardware cos i always found solutions thanks to you but ... i've got a problem !

i made a three-crossfire with 3 XFX HD5850 and i can't activate the crossfire button in the catalyst cos there's only 2 video-card seen in the device manager.

The 3rd VGA is properly plugged.

Have you got idea about this ? the 3rd pci-express port is out of order ?

Does your mainboard support 3way Crossfire?

If you test with GPU-Z do you have 3 GPU's `?

my Asrock Extreme7 Gen3 supports 3way-crossfire; GPU-Z sees 2 GPUs.

I finally found the solution : i interchange the VGA card.

Thanks for your read and answers.
