Notes 1. The memory module sizes available for your server are 32 MB, 64 MB, 128 MB, and 256 MB. At a minimum, your server requires four 32 MB DIMMs in bank 1. 2. The preinstalled memory board contains banks 1-4. The optional memory board contains banks 5-8. Install additional memory in bank 2; then, bank 3, and continue in numeric sequence. This is a guideline but it is not required to populate banks in this order. 3. All the DIMMs installed in a bank must be the same size and speed, but each bank can have different sized DIMMs installed. 4. Your server comes with one memory board and one terminator board preinstalled. The memory board contains four banks arranged in 16 DIMM connectors and supports 4-way memory interleaving. You can replace the terminator board with an optional memory board containing an additional 16 DIMM connectors. 5. Installing or removing memory modules changes the configuration of the server. Therefore, after installing or removing a DIMM, save the new configuration information in the Configuration/Setup Utility program. When you restart the server, the system displays a message indicating that the memory configuration has changed. Start the Configuration/Setup Utility program and select Save Settings. See "Using the Configuration/Setup Utility Main Menu" on page 26 for more information. 6. Consider the memory expansion that is available with the DIMM size you are installing. Table 11. Memory Expansion DIMM Size 32 MB 64 MB 16 Connectors (1 Card) 512 MB 1 GB 32 Connectors (2 Cards) 1 GB 2 GB 128 MB 2 GB 4 GB 256 MB 4 GB 8 GB1 1 Requires greater than 32-bit operating system memory support, or device driver support. Your server provides two features that increase memory access speed: address bit permuting (ABP) and card-to-card (C2C). Netfinity 7000-M10 - Type 8680 149
