Can I Run 200 FSB T-Bird at 266?

Has anyone tried running an unlocked 1.2 T-Bird with a 200MHz FSB at 266? I have been told I may be able to set the multiplier to 9 instead of 12, set the jumper on the board to 133 instead of 100 and voila! Is this true? Any potential harm in trying? So far I have only tried upping the frequency from 100 to 105 and the multiplier from 12 to 12.5. (mobo is a MSI K7T Turbo-R, memory is PC133).

Thanks!

Yes, completely possible and often done.

You can set for 9x133 and run identical clock speed but 33% greater memory bandwidth. You can (if you have a good cooler) probably run it 10.5x133 and still have all your PCI and memory in spec.

well, 100 OC to 133 MHz sure is possible with a gd cooler...
but i was wondering whether i could up my 133 MHz TB with a MSI K7 Master mobo to maybe 150MHz FSB (the more the merrier)???
i know that it depends on the divider of the PCI Bus and the FSB (eg. 1/4, 1/2), but not all mobos is gd at that i think... so is the K7 master able to do that, or am i completely wrong abt the theory of the divider of the buses???
any help would be appreciated...

You probably can, but do you have memory that's rated that high? I ran into that problem a couple nights ago. Memory wouldn't go as high as I wanted it to.
