As some of you know, I have a crap motherboard. It will not lock the PCI/AGP bus speeds, so I can't do much of an overclock without screwing something up. However, I might have found a way around this. On my motherboard, there is a jumper. It allows me to change my FSB to either 133, 166, or 200. I also think it resets the memory and PCI speeds to stock settings. Therefore, I should be able to change to a 166MHz FSB, but my PCI and RAM will not be affected. Also, this would give me a speed of about 2.1GHz (smokin' for a 1.67 chip). However, I would probably kill my chip with stock cooling. Has anyone on these forums ever clocked an XP 2000 to these speeds?
