Did you install the OS with both cards installed?

In Catalyst Control Center, do you definitely not have this crossfire screen:

Try uninstalling the drivers, use driver sweeper or similar to clean the drivers. Once cleaned, reinstall the latest drivers.

If the drivers with both cards installed did not work, try installing the drivers by removing one card, re-install drivers to check if crossfire is enabled on a single x2 first. If it is, add the second card.

Long shot. uninstall driver> shut down systen>unplugg> remove 1 of the cards> restart and either let windows install the driver or download the latest driver for your card to you desktop and point windows to it for installation.Shut down system>unplugg> reinstall the second card and crossfire bridge. restart system and let windows install the driver you installed for the first card. restart and see if you get the crossfire program in the CCC.
