I have a motherboard that can support 100MHZ bus and up to 800MHZ clock speed with slot 1. I want to put a Pentium III but I have a hard time finding that processor. My question is: Can I install a PIII with higher specifications like 133MHZ bus with 800 or 850MHZ speed. If no, why. If yes, what are the advantages? Any other alternatives? Only interested in Pentiums.
