Re: Will a 400MHz FSB Processor work in a 333MHz FSB motherboard?

Putting a processor into a board that has a lower FSB will run it underclocked, if the BIOS recognises it and runs at all. It won't try to run at the rated FSB, as the board won't have components and BIOS that are capable. BIOS is what determines the speed, more so than the CPU itself.
