The Crossfire X option in Catalyst Control Center is missing after updating my drivers to Cat 9.4.

This is on a brand new Dell XPS 630 with dual Radeon 4870s. I know Crossfire X should work because it was enabled on the initial build. I uninstalled the old drivers, rebooted into safe mode, used driver cleaner, then restarted and installed the new drivers. It detects both cards in my device manager, but in CCC it says the second display adapter is "disabled" and there is no Crossfire X option.

I've even tried uninstalling, then removing the 2nd card & XF bridges, then installing the first card on its own, then shutting down, installing the 2nd card without CF bridges, then restarting (upon which windows auto-detects the 2nd card). Then I shut down and install the XF bridges, but there is still no crossfire option in CCC.
