make sure your antivirus is disabled all the way for this:
download DDU and uninstall/clean your current driver settings with it.
now install the latest drivers (16.1.1) and reboot
the enable/disable crossfire settings should now appear when you select advance settings under crimson menu.
now you can re-enable your antivirus. this worked for me (3 x 290x )
