Help with Crossfire/Graphics card detection

[jawanda93]

Hi,

Currently I have two 7970's installed into my ROG rampage extreme 5 motherboard. Where you can turn off the pci slots, there is a light showing on one of them [the second one]. I have updated my cooling system but I dont think the desktop/windows is detecting the second card because I cannot enable crossfire/it is not showing the second card in ccc or option to enable crossfire. However I have plugged a monitor into both cards and they both seems to work. I have 1 monitor plugged into the top card and 1 plugged into the other and it shows windows fine. How can I get them to crossfire, do I have a dead card ? it is difficult for me to unplug and replug the card into the pci slot because I have hard line water cooling, and yes I tested the card before putting them in the machine.

Reinstalled the AMD drivers?

Didn't forget the crossfire bridge?

Already reinstalled the drivers and the crossfire bridge is installed.

Checked the bios? Maybe an option there to enable dual graphics.Don't know if you have overclocked otherwise reset the bios to optimal default values.
