I've noticed that some people are able to overclock their CPU with no problem. One of those people is tjkotula. I have the same motherboard as he and the xp1900 CPU, but every time I try to overclock it or even go to 133 FSB it locks up and refuses to reboot. I have to do the default jumper thing... Can any one give me some advise? I have to set the bios to 130 FSB for it to reboot.
