Help get 6th card to work on MSI G45-z87

[zak9494]

Hey guys I have a MSI G45-z87 and trying to get the 6th card to work.

In control panel under device manager the computer sees 6 cards with no error sign over any of the cards.
In CGwatcher it sees the 6th card but has a "-" in stead of "6"  ~ not sure what that means

Ive tried uninstalling catalyst and reinstalling it. Restarted multiple times but nothing.
Im using catalyst 13.11 Beta 9.5.
Running windows 8.1

Please help!
Thanks
