[Cyrex]

I need more than 1.85v on KT7E mobo how can i do this because my proccessor needs more voltage (duron 750 @ 7.5x133=1000Mhz) because when i lower the voltage a bit it crashes in the bios so my conclusion is that it needs more voltage in windows it runs fine only crashes at Quake3 after a while Fatal error or something but it's not totally locked up i can go back to windows! Sorry for my poor english i am from holland so! Thanx
