" By the way, I have not tried this with a C640, but the C840 (same
" 845MP chipset and similar processors) works with 2GB of RAM. It's not
" supported or documented by Dell, but I have at least one C840 running
" with two DDR2700 1GB sodimms here. It takes longer to boot of course,
" but it can give a bit more life and headroom to your machine if it
" works.

" if you'd like to take a look.)

you don't mention it, but this phenom is well known among apple
machines, and the trick is the correct geometry/density.  generally at
any size there are two chip densities.  so if the mem controller can
handle both 16 x 16M and 8 x 32M sticks, then it can also handle 16 x
32M...  but they'll never advertise it for fear that some moron luser
will try some other 512M geometry and sue when they don't work.
