There are motherboards that will multiply the busspeed with 3/4 if they have
a busspeed at 133mhz. The ASUS P2B does it for example.
So the problem you've mentioned wil not happen then (133 x 3/4 =100mhz)
I have a PII- 350 boxed version at 463mhz and it has no problem at all. I
have forced some extra cooling and there u are.
GPL flies!
