i've got a 6990 and a 6970 set up in my pc. the problem is that it disables the 6970 and the crossfire option is no longer in my ccc. i had the 6990 installed first with the 11.4 preview drivers and everything worked fine. i recently installed the 6970 and the crossfire bridge together, everything booted to windows fine. it started installing the adapter for the 6970 and it blue screened on me. when it re-booted to windows, everything seemed fine. however, there is no option for crossfire anywhere and ccc disabled the 6970. windows device manager now shows that one of the two 6990 adapters has an error. i've tried installing the actual 6970 drivers along with the 6990 drivers and no help there. i've tried removing the crossfire bridge as well, nothing changes. do i only need the 6990 drivers? is there a specific order and set of drivers i am supposed to use to get everything functioning correctly? if i need to, i can uninstall all the drivers and cards and re-install everything if necessary. i just want to get it right. i appreciate the help, thanks.
