Can anyone recommend a BIOS (Non OC edition) that works well for an MSI 7970 OC Edition?  
( R7970 - 2PMD3GD5/OC  http://gpuz.techpowerup.com/14/01/16/gyd.png )

I've tried everything currently listed for MSI on techpowerup.com without much success.  (http://www.techpowerup.com/vgabios/index.php?architecture=&manufacturer=MSI&model=HD+7970&interface=PCI-E&memType=&PmemSize=)

Printed on the PCB Board: "V277 Ver 1.0"

Thanks for any suggestions!
