Can I use a FSB 533mhz CPU in board with FSB 400 Mhz?

[Jose Oliveira]

I have a Fujitsu Siemens Amilo L1300 runing a Pentium M 725. (Originaly was celeron (banias) M340)
I already have 1GB of RAM (max)
I would like to put a better CPU.. M770 or M780. Well I will prefer the M770 because you can get them on ebay for a few dollrs. And the diference of performance for M 780 is tiny. The diference of the price is a fraction...

The question is my Board is only fsb 400. Any problem to put M770 / M780 due higher FSB?
I consider to put M765 that works cause fsb is 400 mhz... but the prices on ebay 40, 60 USD .... each .... The M770 only a 10 or less !
For the same mony of M765 you take the M780 !!!

Thanks on Advance

All help is welcomed
