[NTLUG:Discuss] OT:strange memory activity

[Burton M. Strauss III]

As was pointed out earlier, your older machine probably doesn't recognize
more than 64M per bank.  Often each side is a separate bank.  So with a
double sided DIMMs, you have two banks that the MB can recognize.  This
design is common on 3 DIMM motherboards - you can have only four banks
between the 3 sockets.
