Performing a Memory Upgrade

Use the following procedure to perform a memory upgrade to the system board:

1.Remove the left computer cover.

See “Removing the Computer Covers” in Chapter 7.

CAUTION: See “Protecting Against Electro- static Discharge” in the safety instructions at the front of this guide.

2.Locate the DIMM sockets in which you will install or replace DIMMs.

Figure 8-1 shows the location of the DIMM sockets on the system board.

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

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

4.Replace the left computer cover, reconnect the computer and peripherals to their power sources, and turn them on.

After the system 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.

NOTE: If the memory total is incorrect, turn off and disconnect the computer and peripherals from their power sources, remove the computer cover, and check all the installed DIMMs to make sure they are seated properly in their sockets. Then repeat step 4.

The system detects that the new memory does not match the system configuration information, which is stored in nonvolatile random-access memory (NVRAM). The monitor displays an error message to that effect, ending with the following words:

Press <F1> to continue; <F2> to enter System Setup.

5.Press <F2> to enter the System Setup program, and check the SYSTEM MEMORY category in the system data box on the System Setup screens.

The system should have already changed the value in the SYSTEM MEMORY category to reflect the newly installed memory. Verify the new total.

NOTE: The value of SYSTEM MEMORY is given in kilo- bytes. To convert kilobytes to megabytes, divide the kilobyte total by 1024.

If the total is incorrect, one or more of the DIMMs may not be installed properly. Repeat this procedure again, checking to make sure the DIMMs are firmly seated in their sockets.
