Welcome to the forums.

That sounds like a pretty good OC for an x800 series card. Generally, the best way to increase overclocking capabilities is to provide better cooling, but I'm not sure that would help you much since you're only running around 45°C (assuming that's the load temperature). It is possible that you're GPU RAM is getting hot, which may not be detected by the temperature sensor (which is likely on the core). Adding some quality GPU RAM heatsinks may help you push things a bit harder.

What PSU do you have? This seems like a power issue if the system shuts down when o/cing your card.

his have applied a ati silencer that cools the cpu and the memories on the front and a kind of big cooler on the back. So the tempratures at the mems are OK!


-I have a 400w psu

Just a generic 400W psu? Had the same problems o/cing an x800pro with a 560W Thermaltake PSU. As soon as I switched to a more powerful psu I could go higher without any shutdowns.

Yeah, if it came with a case, it's not likely to be a very powerful for o/cing. Should be fine for general use though. Check the specs for it and see what the 12V Rail is rated at. If it's less than ~24 Amps, then it is likely to be the problem. The TT one I used to have was about 20A and it was the culprit.

Yeah, it's quite low. Something with a bit of extra juice should help here.
