It can be done ,but I wouldn\'t advise it .
I did this once with my 440bx motherboard ,and got a lot of automatic resets .Bringing down fsb to 100 did help some . I finally got me a p3 700 fsb 100 and the errors and resets were paased time .The memory is still 133 sdram but that doesn\' matter .The only thing is it functions as 100 fsb memory .
Anyway if you really want to try , it\'s up to you .
