I ran overall system benchmark with Sandra using catalyst 11.11 and got a 3.93 kpt. Remembering that 12.11 beta had improved performance of some cards, I downloaded that and Sandra failed while benching GPU specfic operations.
I though that maybe it is related to running a "beta" driver and so I removed that and installed 12.10 but it still fails while benching though it is not as bad as with 12.11. i.e it does perform a few more gpu tests before crashing.
error code that I get is 339 (open GL device/render...something..dont remember)
I still have to try benching without the overdrive OC.
I am unable to identify the problem or mistake that I am doing
