Nope. I'm testing with CoD4 or that RHXDRBL or whatever. But the latter is mostly for temps. CoD4 started up, played for a bit then the display driver failed. :/

Yeah, you're card just doesn't overclock very high. Nothing you can do about it except get a new card.

..PSU possibly?

If you have a DMM, you can measure the gpu voltage on the card, to see if its dipping into unstable ranges.

As for cooling.. I have had no issues with my stock cooler handling a 735mhz core/ ~1870mhz shader/ 2ghz mem, OC for benching and max clock & 705/1750/960 for regular gaming use.

I use the Antec Earthwatts 430w. Shouldn't that be enough for my system?

I believe that a OC'd 8800gt can use over 200W on peak load... that would not leave much room for voltage regulation, considering you only want to use ~70-80% of your available PSU power.

With your CPU at 3ghz+ it would approaching ~100-130w on load as well... I am sure you can figure the numbers. :O
