I just put together my first watercooled PC. I have an Asus P5VD1-X mobo and I am haveing a very hard time getting more than a 10% overclock. Cooling is not an issue. 73 F @ 10% over clock. I have a 3Ghz P4. When I try to pushi it higher than 10% it will boot and start to load windows but will go to blue screen for a fraction of a second then reboot. From what I can tell there is not way to change voltages yourself. If anyone has any experience with this mobo I'd love to get some tip. With my old Abit mobo I got it up to 3.6Ghz air cooled so I know it can be done.
