Memory modules Adding system memory to the server can make programs run faster. You can increase the amount of system memory by installing options called memory modules. The maximum amount of system memory the server supports is 384 MB. You can add memory to the server to increase system performance. The server has three connectors for installing system memory modules. Note The following illustration is for reference only. Before you install memory, be sure to check the orientation of the server system board for the correct connector locations. To locate the memory connectors on the system board, see "System board illustration" on page 142. DIMM 0 DIMM 1 DIMM 2 The memory modules that the server uses are dual-inline memory modules (DIMMs). The DIMMs that come with the server are synchronous dynamic random-access memory (SDRAM) with error checking and correction (ECC). These memory modules have a speed of 100 MHz. You can add extra memory modules or replace existing memory modules. When installing or replacing DIMMs, follow these guidelines: The server comes with one or more dual-inline memory modules (DIMMs) installed. Install DIMMs with a maximum height of 6.35 cm (2.5 inches). Use only 3.3 V dc unbuffered, 100 MHz SDRAM DIMMs. Each memory connector supports a maximum of 128 MB of memory. However, the maximum amount of system memory the server supports is 384 MB. Install only ECC DIMMs to enable ECC. If you install nonparity (NP) DIMMs, the server will not power up, and POST memory error code 164 will be displayed. 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 (DIMM 2). After installing or removing a DIMM, you must save the new configuration information using the Configuration/Setup Utility program. See 126 Netfinity Server HMM
