The Dell motherboard detects the CPU's FSB and sets it that way. The board officially supports 66/100/133. My Celeron 700 runs at 66FSB, but I'd like to try 100FSB so my memory will run at full speed and I can see if the CPU can handle 1050 (10.5x multiplier). Does anyone know of a way to set the FSB in software? - Grant -- gentoo-user@gentoo.org mailing list

My (perhaps limited) understanding tells em that running a 66MHz chip at 100MHz blow it sky high. Although according to this web site[1] that's ok for celerons. I'd make sure you have some pretty decent cooling though - ie. water cooling, or move to Alaska. If all you want to do is run the RAM faster, what you usually have is a FSB to RAM multiplier (can't remember what it's called - my overclocking days are long gone :) Which allows you to run the ram at 100 or 133... Does anyone know of a way to set the FSB in software? Not me! My best recommendation would be to buy a really good overclocking motherboard - one with all these features in the bios. You should be able to get S370 mbs on ebay for cheap.
