I have 1 512 and 1 256 micron ddr333, samsung 40 gb 7200 rpm hard drive, good 400 watt power supply, etc... I can only run at 166 mhz and below, it wont boot at 200mhz. When I change the CPU multiplier, all I get is lower than what the 2600 normally does, which is 2.13 ghz. Any sugestions on multiplier setting, or memory settings? I had the 2400 xp before and got it up to 2.26 ghz, but I havent had any luck with this puppy....
