CGMiner Crashing

[CRSbeast]

I have a XFX 6950 card running on 1408 shaders (Original) and am trying to mine with CGMiner. CGMiner starts just fine and says I'm getting M/hash but according to BTCGuild I'm inactive. This stumped me because I could mine just fine with my 6670 Card. My system is: (1) XFX 6950 (1) Corsiar 4GB Ram Stick 1600 (1) ASUS P8Z68-v PRO (1) Intel i5 2500K and running on Windows 8 64-bit. The card is not over clocked or messed with I'm running on the number 2 BIOS switch and getting ~330-40 Mhash. Anyone else that has had the same problem or have a way to fix this issue would be greatly appreciated thanks.
