Removing and Replacing System Memory DIMMs
The server comes with four or eight DIMMs installed. The server is minimally configured with
1 GB of memory (four 256 MB DIMMs loaded in quad 0 (slots 0A, 0B, 1A, and 1B). The server is
maximally configured with 32 GB of memory, eight 4 GB DIMMs loaded in each of quads 0 and
1 (quad 0 slots 0A, 0B, 1A, and 1B, and quad 1 slots 2A, 2B, 3A, 3B).
You can replace these DIMMs, or insert DIMMs into unused quads if desired. When adding
DIMMs, you must use a minimum of four like-sized DIMMs in the next available quad. If you
are installing DIMMs of different sizes, you must install the largest DIMMs (most memory) in
the first quad. DIMMs in the second quad can be equal to or smaller than (less memory) the
DIMMs in the first quad. If you install DIMMs in the third quad, they must be equal to or smaller
than the DIMMs in the second quad.
Supported DIMM Sizes
Supported DIMM sizes are 256 MB, 512 MB, 1 GB, 2 GB, and 4 GB. You can use dissimilar DIMM
sizes in the server, but all four DIMMs in each quad must be identical.
