Not always, a lot of MBs (don't know about this one in specific) have 
problems running the CPU front side bus at a different speed than the 
memory (the XP 1800 has a FSB of 133MHz, 266 DDR) and unless you have 
on-board graphics sharing the memory bandwidth, or it's an SMP system, 
it doesn't really achieve much even if it does work, although you could 
underclock the CPU with multipliers and overclock it on the FSB so it 
runs at approximately the same frequency but with greater memory bandwidth.
