Heck, just find out exactly what flavor of RAM the box takes, how many
total slots it has, largest card it can handle per slot, etc., and
we'll max it out. It can't be that
expensive, ECC or not.
(I don't remember what it cost, but I put 512 MB DDR-2100 ECC RAM into
the machine I built for myself last spring, and it didn't break the
budget.) If I knew what it needed I'd probably just ship OpenForce
some RAM right now.
Incidentally, while I've never used the Linux version, the non-free
program seems very useful for spitting out hardware and configuration
info. But, it doesn't actually seem to report any info about the
type of RAM in the system, so oh well.
