Unless you overclock the 167Mhz systembus - that needs PC2700 (333Mhz) ramsticks - faster ram sticks aren't going to do anything noticably to your computer. If you put a faster cpu, the memtest will be better ... but still the PC2700 sticks will handle that without problem. So kind of useless to put expensive sticks in there that are made for people who overclock windowsboxes.
