Can you put a 533mhz fsb 478 socket processer in a 40mhz fsb mobo. The mobo I have only has 400mhz fsb support
that was your question well what id say about that is i would think the fsb would clock at 400mhz if thats all the motherboard can support then again i dont know cuz ram and motherboard is too different things
my process is 533 bus its a celeron D but i have pc3200 DDR ram that really can clock at 400mhz but it clocks at 333mhz cuz my fsb is 533 when id need to have a 800mhz fsb in order to clock it at 400mhz
id say this tho id recommend you looking into getting a mobo that can work with your processor that supports 533 fsb processor
