Working with Memory Modules The memory modules that your server uses are dual-inline memory modules (DIMMs). The DIMMs that come with your server are synchronous dynamic random-access memory (SDRAM) with error correcting code (ECC). These memory modules have a speed of 66 MHz. You can add extra memory modules or replace existing memory modules. Notes: 1. Your server comes with one or more dual-inline memory modules (DIMMs) installed. 2. Install DIMMs with a maximum height of 6.35 cm (2.5 inches). 3. Use only 3.3 V unbuffered DIMMs. 4. The server supports 32 MB, 64 MB, and 128 MB DIMMs. 5. When you are installing memory modules, install them in adjacent connectors, with no vacant memory connectors in between. 6. If you are installing DIMMs of different sizes, install the DIMMs with greater memory capacity starting with the connector closest to the edge of the system board (Bank 0). 7. After installing or removing a DIMM, you must save the new configuration information using the Configuration/Setup Utility program. See "Using the Configuration/Setup Utility Program" on page 28. 8.
