Sadly No.... P3V4X'ers will be stuck with their Coppermines....
" There is - of course - a downside to the new Pentium III processor as well. It may have the same socket (Socket370) as the good old Coppermine, but it requires a different I/O-voltage and thus a different chipset. Right now, you need a new version of Intel's 815 chipset (i815 EP B-stepping) to run the new PIII. Current PIII-boards won't be able to host the new breed. " - Tomshardware
