Memory Modules

The six memory module connectors on the system board can accommodate 256 MB to 6 GB of registered memory modules. The memory module connectors are arranged in pairs which consist of three banks.

Memory Upgrade Kits

The system is upgradable to 6 GB by installing combinations of 128-, 256-, 512-MB, and 1-GB registered DDR SDRAM modules. You can purchase memory upgrade kits as needed.

NOTE: The memory modules must be PC-1600 compliant.

Memory Module Installation Guidelines

Memory module connectors are arranged in pairs, labeled A and B. Each pair of modules forms a single bank. See Figure 5-3 to identify memory module connectors on the system board.

When you install memory modules, follow these guidelines:

•You must install memory modules in matched pairs.

•Install identical memory modules in connectors A and B for bank 1 before installing modules in connectors for bank 2, and so on.

Table 4-3 lists several sample memory configurations based on these guidelines.
