Memory DIMM Configurations

The memory board contains sixteen 168-pin DIMM
sockets for a total of up to 4 GB of system memory,
using 256MB DIMMs. See Figure B-1. DIMM sockets on
the board are organized as four 72-bit wide, 2-, or 4-
way interleaved banks. For example, a 4-way
interleaved bank requires four DIMMs. DIMM sockets
accept 168-pin single- or double-sided DIMMs. A bank
must be populated using identical DIMMs. DIMMs may
vary in size from one bank to the other, but all DIMMs
must be the same speed. Timing requires 60 ns fast
page devices.

A memory DIMM upgrade kit consists of 2 or 4
identical (of the same size and type) DIMMs defined as:

2 x 32MB DIMMs = 64MB

4 x 32MB DIMMs = 128MB

4 x 64MB DIMMs = 256MB

4 x 128MB DIMMs = 512MB

4 x 256MB DIMMs = 1GB.

The 2 x 32MB DIMMs upgrade kit is used only for
servers that were originally shipped with 64MB (two
32MB DIMMs) of memory.
