The Pentium 3 you are looking at in question is the 933MHz one that is at 133MHz bus speed. Going by your motherboard manual you can have a P2/P3 from 350MHz to 700MHz @ 100MHz. So the answer is a no by the looks of it. Good place to find info on the Pentium chip specs is to find the CPU info chart thing they have here on Toms Hardware. But I can't find it ARRRGGHHH!! They had it on here a while ago.
