Main Storage

All main storage on the Model 270 is feature main storage. A minimum of two of the same
capacity and technology must be selected.
Processors #2248, #2250, #2422, and #2252/#2423 (without #2884 Main Storage Expansion
card):
• All main storage DIMMs on the these Model 270 processors must be added in pairs of
the same capacity and technology.
• There are eight slots available in the base system for main storage DIMMs, which plug
directly onto the processor (Direct Attach) and do not use a #2884 Main Storage
Expansion Card.
• For Processors #2252/#2423, when more than eight total DIMMs are required, a
#2884 Main Storage Expansion Card must be ordered as a separate priced feature. All
DIMMs must plug into the #2884 Main Storage Expansion Card. When the #2884 is
used, direct attach of DIMMs to the processor #2252/#2423 is not allowed.
Processors #2252, #2253, #2423, and #2424 (all with #2884 Main Storage Expansion Card):
• Model 270 Processors #2252, 2253, #2423, and #2424 using the #2884 Memory
Expansion Feature must place DIMMs of the same capacity and technology, in sets of
four (quads). A single pair of DIMMs is allowed on the initial order if they are the only
two on the system. Any memory DIMMs added beyond the initial pair must be placed
in quads. The initial DIMM pair must also be in a quad.
• There are 16 slots available in the base system using a #2884 Main Storage
Expansion Card for placement of main storage DIMMs.
• For processors #2252/#2423, when more than eight total DIMMs are required, a #2884
Main Storage Expansion Card must be ordered as a separate priced feature. All
DIMMs must plug into the #2884 Main Storage Expansion Card.
• For processors #2253/#2424, a Main Storage Expansion Card (CCIN 2884) is
included in the base system. It does not need to be ordered.
#2884 Main Storage Expansion Card
• This feature provides for mounting DIMM memory on the Model 270. It contains one
riser card with 16 sockets for placement of 128 MB, 256 MB or 512 MB DIMMs.
• Maximum: One on Processor #2252 and #2423.
