well i did what you said and it's 200. 133 only appears when you enable overclocking in the bios. as such i think that 133 is the default setting when overclocking as it's making sure you don't accidentally overclock maybe. i left it at 133 and applied the settings. when i went into windows it showed my FSB as 133 and i had therefore reduced the power of the processor. so i went back to my bios and put it up to 205 and it worked fine.
