System Memory

You can upgrade your system memory to a maximum of 16 GB (for a one- processor configuration) or 32 GB (for a two-processor configuration). You can install 667-MHz registered parity DDR2 memory modules (DIMMs) in sets of 512-MB, 1-GB, 2-GB, or 4-GB modules. The memory sockets are located on the system board under the processor shroud and are split into two separate groups of four sockets each. Each four-socket group is adjacent to its respective processor.

General Memory Module Installation Guidelines

To ensure optimal performance of your system, observe the following guidelines when configuring your system memory.

•Memory must be installed in configurations of two, four, or eight DIMMs. The minimum configuration for a two-processor system is four DIMMs.

•DIMMs must be installed in matched pairs of identical speed, technology, and size in the following pairs of sockets:

–DIMM A1 and DIMM A2

–DIMM A3 and DIMM A4

–DIMM B1 and DIMM B2

–DIMM B3 and DIMM B4

•Minimum configurations must occupy the lower-numbered sockets (DIMM A1 and DIMM A2 for a one-processor configuration and also DIMM B1 and DIMM B2 for a two-processor configuration).

Table 3-1 shows the available memory configurations following these guidelines.
