actually that board supports both 200mhz fsb and 266mhz fsb
but no it doesnt support the 333mhz fsb and it probably wont be able to run at that speed even if overclocked
im 90% sure that board doesnt have a 1/5th pci divider so if you did manage to overclock the fsb to 166mhz (333mhz ddr) your pci and agp bus would be way out of spec and could kill pci/agp devices, not to mention lack of stability
also im pretty sure it doesnt even support the barton voltage requirements (meaning even if you were willing to run the barton underclocked on a 133mhz fsb it still might not work)
