Memory Module Installation Guidelines

Starting with the socket farthest from the system power supply bay, the memory module sockets are labeled BANK1_DIMM_A, BANK1_DIMM_B,
BANK2_DIMM_A, and BANK2_DIMM_B (see Figure 6-4). When you install memory modules, follow these guidelines:
You must install memory modules in matched pairs.

Install a pair of memory modules in bank 1 before installing a second pair in bank 2.

Performing a Memory Upgrade

To perform a memory upgrade to the system board, perform the following steps.
CAUTION: Before you perform this procedure, you must turn off the system and disconnect it from its power source. For more information, see
"Safety First—For You and Your
1. Open the system doors (see
2. Locate the memory module sockets in which you will install or replace memory modules.
Figure 6-1 shows the general location of the memory module sockets on the system board.
3. Install or replace the memory modules as necessary to reach the desired memory total (see
Modules").
4. Close the system doors, reconnect the system to the electrical outlet, and turn on the system.
After the system completes the POST routine, it runs a memory test. The system detects that the new memory does not match the system configuration
information and displays an error message.
5. Press <F2> to enter the System Setup program, and check the System Memory setting on the System Setup screens.
The system should have already changed the value in the System Memory setting to reflect the newly installed memory.
6. If the System Memory value is incorrect, one or more of the memory modules may not be installed properly. Repeat steps 1 through 5, checking to
make sure that the memory modules are firmly seated in their sockets.
7. Run the system memory test in the system diagnostics.
