I have a 2010 alienware m17x windows 7 64 bit, dual mobility radeon 4870's in crossfire. I just updated to to the 13.9 CCC suite and drivers. Windows device manger says both cards are working properly but CCC says one card is disabled. There is no option for crossfire in the suite??
Problem fixed. Uninstalled latest AMD drivers. Went to Dell website and retrieved Dell drivers from 2010. Installed them and then updated with latest AMD CCC suite.
