The technical manual that comes with the motherboard should tell you
how much cacheable ram it can support. Mine says 64Mb with 256K cache
and I think that's pretty typical. Also, by checking yourself you
bypass the problem of whether your dealer knows what he or she is talking
about.

Hope this helps.
