Hey guys so i recently got a V2 vapor-x 5770 to go with my V1 vapor-x 5770 but have been unable to get them to overclock. Once i overclock them just a bit i get BSOD

On the V1 i had been running it at 965/1350 with voltage at 1.2. I know the V2 is voltage locked so i'm not worried about that. I'm just trying to figure out what the problem is (using MSI Afterburner). Any help would be appreciated, thanks!
 
Hmm well I'm running a stock 5770 and a XFX XXX 5770 in Crossfire.

The stock card is the primary and I have both of them set to run at 900/1300.

I just plugged the XFX in and re-ran the driver install and it just went through the motions. The cards were listed in Overdrive with differing clocks and I just set them to match.

All worked flawlessly. I havent messed at all with voltages.
