Bios helps more?

The big problem is the insane condensation when going from -100°C back to -20°C just to boot. If it would be like -60°C, it would already help quite a lot.

Another issue is some issues with changing clocks in 2D idle. I can complete Vantage at 1150, but increasing the clock to 1200 makes Windows lock up and bluescreen. It seems pretty strange that a difference of 50MHz can mean 3D stable to 2D totally unstable.
