[Duo2400] Re: 2400 Memory?

[Ralph Mawyer]

Tom, Datamem does show different part numbers.

Their price is pretty good, if they really have it in stock.  Not 
many folks even stock them anymore.

The 64MB SO DIMM I have in front of me is just labeled 64M 144P DIMM 
(C5). It uses eight 8MB chips, four to each side.

For purely intellectual interest, it looks like it may be an EDO vs 
non-EDO issue, with the 2400 requiring EDO memory. I browsed a couple 
of articles in the Apple knowledge base and they referenced how a 
2400's EDO ram would not work in a circa 1999 G-3.

This is pretty good summary of the issues:

There are definitely more technically astute folks on the list than 
me that will probably chime in at some point.

I'd probably just order the RAM from Datamem. ;-)
