Memory

Adding memory to the server is an easy way to improve system performance. You can increase the amount of memory in the server by installing options called memory- module kits. Each kit contains one industry-standard, dual-inline memory module (DIMM). Your server uses a noninterleaved memory configuration, which allows you to add, remove, or replace one DIMM at a time. In an interleaved system you would have to add, remove, or replace memory in sets.

The server comes with a dual inline memory module (DIMM) installed on the system board in DIMM slot 1.

Note: Install additional DIMMs in the following order: DIMM connector 2, then 3, then 4. (See the following illustration for memory connector locations.)

Installing memory modules

Complete the following steps to install a DIMM:

Attention: When you handle electrostatic discharge-sensitive devices (ESD), take precautions to avoid damage from static electricity. For details on handling these devices, refer to “Handling electrostatic discharge-sensitive devices” on page 110.

1.Review the information in “Before you begin” on page 42 and the documentation that comes with your option.

2.Turn off the server and peripheral devices and disconnect the power cord and all external cables; then, remove the cover (see “Removing the cover” on page 44 for details).

3.If necessary, remove the PCI card in slot 2 for easier access to the DIMM connectors.

4.Touch the static-protective package containing the DIMM to any unpainted metal surface on the server. Then, remove the DIMM from the package.
