This high of an overclock (200 mhz fsb) is impossible since fastest sdram afaik is capable of 166 mhz. itd be possible to push it some more i guess but then you've got all sorts of latency and timing problems, also the agp and pci are locked onto the fsb so at 166mhz fsb you'd need a 5 divider, with fsb 200 you'd need a 6 divider unless you want to overclock agp and pci aswell.
Not that im against overclocking, when it works its great.
