Thanks for your inquiry. I don't recall the exact specs of the BX6 Rev. 1
but I don't think it has a 1/4 PCI divider, so running at 124mhz or 133mhz
is probably not a viable solution. (If I'm wrong about this assumption,
then one of the 700E cC0 processors that we currently have will work well).
With your current hardware I would recommend getting an 800 or 850 and
clocking it using using the 112mhz fsb available on your board.
