MSI R6950 Twin Frozr II OC voltage issue

post #1 of 4
Thread Starter 
Okay guys, I'm up against a brick wall. I've been trying to get my R695 TF2 to reach a higher OC, but its crashing the driver anytime i raise the core voltage above 1.100 volts. any ideas what could be causing this? here's my specs:

CPU: I7 2600k @ 4.5ghz
Motherboard: Asus P8X68-V
PSU: Raidmax 630W
gpu :MSI R6950 TF2 OC

ATM, i can reach a 890 MHz OC on the core on stock voltage (1.074) or 905 MHZ on 1.100V. again, anyone know what would cause a card to crash when you add more than this? i don't do anything major, wanting to hit 1.174 preferably, but like i said, after 1.1v it crashes, regardless of clocks
