DIMMs

The system board contains four DIMM sockets (Figure 4-15). Each socket can hold a single 72-bit DIMM module with 256MB, 512MB, or 1GB of memory. When all four sockets are populated, the system board supports a maximum of 4 GB of memory with 1GB DIMMs.

Memory is partitioned as two banks of SDRAM that must be populated in pairs, each providing 72 bits of buffered two-way interleaved memory (64-bit main memory plus ECC). DIMMs will always be installed in sockets 1 and 2.

Note: DIMMs are always added in pairs.
