I received my new card today.
I recently RMA'd a gtx760 for the same problem. Could it be my motherboard? As I cant SLI on it but I can crossfire it, is it more AMD based?
I tried the 2 8 pin connectors on my PSU and also using the 2 6 pin with the 8 pin converters that came with it.
It only happens when it is under heavy load and in Uginine valley 1 I get 1730 which seems a bit low? Oh and I managed to get my 760 to 1934 with overclocks.
See my sig for specs.
My 6770 is fine.
Maybe it just isn't compatible with my system and I should return it and go AMD?
Oh and its windows 8 64 bit and I did a frsh install on the 760 which made no difference
