The actual memory array is on a Memory Expansion Card installed in a Memory Expansion Card Connector (MECC) located on the system board.
On the Yh c“nG<< hT p“there are two types of Memory Expansion Cards supporting the following configurations:
Four RIMM sockets support RDRAM ECC and memory modules installed in
. Any unused RIMM sockets must contain a continuity module.
‘QUU aWKSMb I5
‘QUU aWKSMb J5
‘QUU aWKSMb I6
‘QUU aWKSMbJ6
Models are supplied with either 128 MB or 256 MB RDRAM ECC main
memory. Memory upgrades are available in of RIMMs, with an individual RIMM size of 64 MB, 128 MB, 256 MB or 512 MB. The following diagram shows installed memory. There are always two RIMMs working in parallel.
