I wish to upgrade the ram in my Satellite, M30X-S214.  It has a Celeron
M 1.3ghz.   Crucial site recommends PC2700, Cas 2.5, DDR333 ( 2 X 256, 512
or 1024)--which is what is in it now.  Can I use PC3200, Cas 2.5, DDR400 as
a substitute & enjoy the same  performance gain offered by the PC2700?  It
is quite a few $ cheaper.
    Thanks in advance.  s
