as per title. i got MSI 990FXA-GD65. i connected 1 master card on x16 riser and other 5 on x1 risers. i did connect 6pin power onto motherboard. power is fine. all the guides mention catalyst 13.1 from techpowerup site or 12.6 from amd website make 6gpu rig happen - though none of them support new r9 290 cards. im now on 13.11 beta 9. device manager only see 4 video adapters. please advise.
