Every time I try to over clock Beyond 415/ 1.16 on my 6800 gt it fails the coolbits test and wont let me go any futher I have turned th fast writes off and made sure the voltage was at 1.16 and everything seems fine Im running it on an ASUS AV8 Deluxe MB and have the NV silencer on it for added cooling. My temps are fine around 37c - 40c . I was jsut wondering if I was missing some thing or if this card just has low limits I have seen others get 466/ 1.29 on thiers.
