I dunno, if you count the chips what do you come up with?
I recently bought a whole pile of servers (HP DL380s if you've been
following my trials and tribulations) that are designed to accept up to
6Gb on the motherboard. I think it's a bit of a gimmick really.
One of the servers came bundled with 4.5Gb RAM. We wanted 4Gb, but the
machine comes with 512 by default (2x256 chips ). Our supplier just
stuck in 4x1Gb chips without bothering to remove the existing chips. As
the servers all had different chip sizes, 256Mb, 512 and 1Gb, by mixing
and matching I was able to remove the wasted 512Mb and install it in
another server. Maybe you can do something like that. Or put it on a
shelf for spare parts.
 DIMMs, SIMMs, whatever they call them these days.
