Hi, can you mix a 133mhz CPU with pc100 sdram? Getting a P3 1gig 133FSB and have sdram100 for my AX6BC motherboard.

So ram also has to run at 133 MHz. If you underclock the cpu to 750 MHz (7.5x100) then of course no problem for sdram100, cannot be recommended to do so. best regards John

while you can almost ALWAYS run higher speed ram at slower speeds... its a crap shoot for running slower ram at higher speeds... i have done so... i have a handful of PC100 ram running at PC133 just fine.. but then its quality ram... you are taking a chance basically.. r "Jason Pleavin" <jpleavin@bigfoot.com> wrote in message news:a35rqq$15avh4$1@ID-51425.news.dfncis.de... > Hi, can you mix a 133mhz CPU with pc100 sdram? > > Getting a P3 1gig 133FSB and have sdram100 for my AX6BC motherboard. > > >

Maybe I could lower the FSB would that work?

I decided to get 256mb of 133ram. Its all a bit pricey compared to getting a Celeron. But I should see a big improvement on Cel500 and 128mb of pc100 I hope.

It's not the speed in itself, but that the older PC66 RAM and motherboards was organised differently. Best wishes, -- Michael Salem
