Performing a Memory Module Upgrade

To perform a memory module upgrade to the system board, perform the following steps.



1. Remove the optional front bezel, if present. See "Removing the Bezel."

2. Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet.

3. Open the system covers. See "Opening the System Covers."

4. Locate the memory module sockets in which you will install or replace memory modules.

Figure4-6 identifies the memory module banks on the system board and shows the order of the socket designations.

5. Install or replace the memory modules as necessary to reach the desired memory total. See "Installing Memory Modules" or "Removing Memory

Modules."

6. Close the system covers. See "Closing the System Covers."

7. 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.

8. 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.

9. If the System Memory value is incorrect, one or more of the memory modules may not be installed properly. Repeat step 2 through step 7, ensuring

that the memory modules are firmly seated in their sockets.

10. Run the system memory test in the system diagnostics.

11. Replace the optional front bezel, if applicable. See "Replacing the Bezel."

Installing Memory Modules

To install a memory module, perform the following steps:

1. To open the memory module socket, press down and outward on the socket latches. See Figure4-7.

Figure 4-7.InstallingaMemoryModule



2. Align the memory module's edge connector with the slot in the center of the memory module socket, and insert the memory module straight down into

the socket. See Figure4-7.

The module and the socket are keyed to prevent misalignment.

3. Press down on the memory module with your thumbs until the latches snap up around the module, securing it. See Figure4-7.

When the memory module is properly seated in the socket, the latches on the memory module socket should align with the latches on the other sockets

with memory modules installed.

Removing Memory Modules

To remove a memory module, press down and outward on the socket latches on each end of the socket until the memory module pops out of the socket. See

Figure4-8.

CAUTION: Only trained service technicians are authorized to open the system covers and access any of the components inside the system. See

the System Information Guide for complete information about safety precautions, working inside the system, and protecting against electrostatic

discharge.
