4.Install or replace the DIMMs as necessary to reach the desired memory total.

Follow the instructions in “Installing a DIMM” or “Removing a DIMM,” as appropriate, later in this section.

5.Replace the system board according to the instructions in “Replacing the System Board Assembly” in Chapter 6.

6.Replace the computer cover according to the instructions in “Replacing the Computer Cover” in Chapter 6, reconnect your computer and peripherals to their power sources, and turn them on.

After the computer completes the power-on self-test (POST) routine, it runs a memory test that displays the new memory total, which includes all newly installed memory.

The system detects that the new memory does not match the system configuration information, which is stored in nonvolatile random-access memory (NVRAM), and generates the following error message:

System memory size has changed — Run Configuration Utility

Press F1 to resume, F2 to Setup

7.Press <F2> (when prompted while the computer is booting) to enter the System Setup program, and check the Extended Memory category on the main menu of the System Setup screens.

The system should have already changed the value of the Extended Memory category to reflect the newly installed memory. Verify the new total.

NOTE: If the memory total is incorrect, turn off your computer and peripherals and disconnect them from their power sources. Remove the computer cover and system board, and check all the installed DIMMs to make sure they are seated properly in their sockets. Then repeat steps 6 and 7.

8.Enter the EISA Configuration Utility. Then save the configuration and exit the utility.

Running the EISA Configuration Utility and saving the configuration is required for the system to recog- nize the newly installed DIMMs. See Chapter 5,

“Using the EISA Configuration Utility,” for instruc- tions on running the utility and saving the configuration.

9.When the Extended Memory total is correct, run the diskette-based diagnostics to test all installed DIMMs.

See the chapter titled “Running the Diskette-Based Diagnostics” in your Diagnostics and Troubleshooting Guide for information on running the memory diagnostics.

Installing a DIMM

NOTE: The following procedure assumes that the system board assembly has been removed from the computer and is laying on a flat work surface. See “Removing and Replacing the System Board Assembly” in Chapter 6.

Install DIMMs starting with socket DIMM_A, located nearest the PCI expansion-card connector, and working toward socket DIMM_D, nearest the center of the system board. If a DIMM is already installed in the socket you need, you must remove it. Follow the instructions in the next subsection, “Removing a DIMM,” if appropriate.)

Use the following procedure to install a DIMM:

1.Press the ejectors on the DIMM socket down and outward as shown in Figure 7-6 to allow the DIMM to be inserted in the socket.

2.Align the DIMM’s edge connector with the slot in the center of the DIMM socket, and insert the DIMM in the socket.

The card-edge connector on the DIMM is keyed so that the DIMM can only be installed in the socket in one way (Figure 7-6).

3.Press down on the two outer edges of the DIMM with your thumbs while pulling up on the ejectors with your index fingers to lock the DIMM into the socket.

When the DIMM is properly seated in the socket, the ejectors on the DIMM socket should align with the ejectors on the other DIMM sockets.
