Memory Module Installation Guidelines
The memory module sockets are arranged in banks (1 and 2) on two channels (A and B). Unless only one 256-MB memory module is installed, the modules
must be installed in identical pairs. For example, if you are installing 512-MB of total system memory, sockets DIMM1_A and DIMM1_B (bank 1) must contain
256-MB memory modules.
Starting with the connector closest to the processor, the memory module sockets are labeled "DIMM1_A" through "DIMM2_B" (see Figure A -3 ). When installing
the memory modules, use the following guidelines:
l Use only DDR-400 memory modules.
l If you are installing one 256-MB memory module, install the module in the DIMM1_A socket.
l If you are installing 512-MB or more of total memory, install identical memory modules in a bank.
The memory module banks are identified as follows:
¡ Bank 1: DIMM1_A and DIMM1_B
¡ Bank 2: DIMM2_A and DIMM2_B
l Unless only one 256-MB memory module is installed, bank 1 must contain two identical memory modules. However, you can configure bank 1 and bank
2 with different size memory modules.
l Installing three memory modules is not supported.
l Install memory modules in bank 1 (DIMM1_x) before installing memory modules in bank 2 (DIMM2_x).
Table 6 -1 lists the supported memory module configurations for the system.

Performing a Memory Upgrade
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2. Remove the bezel. See " Removing the Bezel " in "Troubleshooting Your System."
3. Lay the system on its right side.
4. Remove the cover. See " Removing the Cover " in "Troubleshooting Your System."
5. Remove the cooling shroud. See " Removing the Cooling Shroud ."
6. Install or remove memory modules as necessary to reach the desired memory total. See " Installing Memory Modules " and " Removing Memory Modules ."
See Figure A -3 to locate the memory module connectors.
7. Install the cooling shroud. See " Installing the Cooling Shroud ."
8. Install the cover. See " Replacing the Cover " in "Troubleshooting Your System."
