Thanks again, it's all a lot clearer now, before OC'ing was a 'Mysterious Art' known only by you guys and possibly Ninjas... Heat is a problem, especially with stock cooling. I've got the air flow sorted, but really need to look in to a new HSF. Would that 'unlock' higher clockspeeds? Or just make performance better at current clock speeds? I understand the whole Temperature affecting Resistance thing perfectly, but would higher clock speeds be attainable?
I know that Japanese guys and Toms have got a P4 up to 5Ghz with extreme cooling, but I can't see how the cooling would make the 'Test' feature work better.
Basically, does the temperature affect the 'Test' feature on Coolbits?
If you care to know, the nvidia coolbits "detect optimal frequencies" runs on an algorithm dependant on heat and rendering accuracy, when it detects either too much heat being produced, or a loss in rendering accuracy (artifacts or otherwise) then it'll back down 5mhz and stay there. If your card is cooler, there is less resistance, better conductivity, and therefore you can almost always attain a higher clockspeed than without.
btw the 5ghz was nothing compared to some 8ghz overclocks they have running without having to fill up a tube with liquid nitrogen (using phase-shift cooling instead).
