Duh. Re read what you wrote. If you put a 133 bus CPU on a 100 bus board it'll just run slower. Same multiplier at lower bus speed. The catch is there were multiple varieties of the 1.0 GHz p3 with different voltages so just make sure you're using a .25 micron pentium 3 and the voltages should be close enough. .18 micron p3s (I forget if they ever came as slot 1 but adapters exist ) or "Tualatin" p3s run at a lower voltage and have some other minor adjustments to the socket.

A quick search on Vogons - pentium 3s are generally fully locked multipliers - can't go up or down.
Xeons though could have their multipliers reduced. Engineering samples of p3 of course can do all sorts of things.
I'm not sure if you can put a slot 1 CPU on a slot 2 board. Bios support at least would be required.

Anyone know if such can run or be made to run at a speed lower then it's rated? Specifically can a 1ghz 133mhz piii run in a mobo that normally takes a 700mhz 100mhz piii?
