It could be that your PSU isn't providing enough power. 350W may not be enough for a 6800 Ultra...At default speeds, do you have any problems running 3DMark or games?

That PSU isn't providing enough power for overclocking. Monitor your GPU temps carefully, and take a look at what's actually coming out your PSU (these are normally ideal figures). Oh, and, don't bother overclocking such a beautiful card yet.

if it shipped overclocked and You are not watercooling or using another source of cooling besides Factory cooling then you probably will not be able to overclock an overclocked card.

Nope, The 6800GT are Not that good on BENCHMARKING the X800 are the best in BENCHMARKING but, The 6800GT is very good in Quality hammers the X800XT in Quality But Benchmarking Nvidia have stuffed up again. And make sure you have all your drivers installed Corrctly and I reakon you shou;d be getting CORE: 400 and Memory:1.2mb I got these Overclocked MARKS From a Friend Oversea's He lives In America New York.
