Hello ALUG,
A couple of days ago I asked about checking out RAM info on a running machine and was pointed to the dmidecode program.
I know its a little OT but....
I've been able to work that new modules should be: max module size: 512MB; voltage: 3.3V; single-bit ECC error correction. But I wonder if anyone knows if its possible, given the information below, to work out what size (in pins) and speed (PCnnn) will be compatible?

Oh dear, the type of memory you need is RIMM RDRAM PC800 (a patent encumbered memory design by Rambus inc.)
You should be able to get this from someone like Scan, alternatively you can mail me off list and I can get you a quote from my company "Crimson Technology"
Warning - it's not cheap and AFAIK has to be installed in pairs. It can also in some circumstances interact badly with the existing pair, although that is less common now.
