crossfire x internal bridge interconnections linking your graphics cards together are not properly attached. Iv tried changing out the bridges uninstalling reinstalling the drivers reinstalling cards. Both cards are functional separately is their anything i should try?

Fully uninstall and reinstall CCC, rather than just updating it. Also fully reinstall / remove any previous CAPs you may have installed, as well as GPU monitoring programs.

Youre positive it is a Crossfire connector? i have seen people use a connector that came with their mobo and it be an SLI bridge. Did it come with one of the GPU's?

have you tested each individually? also, make sure the power connectors are properly clicked in and each cards are fully in the lane. If you are using an ivy bridge processor it may be using PCI-E 3.0 in one lane and not in another which would disable crossfire. can you list system specs?

I have tested both individually they both work just fine by themselves.

how many total connectors have you tried? i suggest going to newegg or amazon and ordering 2 new ones, people have had this problem before and were told even by customer support to buy a new bridge. One unlucky fellow tried 4 and none worked. Bought 2 new ones from amazon and the 1st worked out of the box.
