1. Remove the computer cover.
See “Removing the Computer Cover” in Chapter 7.
2. Remove the support panel.
See “Accessing the Microprocessors, Memory, or System Board” in Chapter 7.
3. Locate the DIMM sockets into which you will install or replace DIMMs.
Figure 8-1 shows the location of the DIMM sockets on the system board.
4. 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.
5. Replace the support panel.
6. Replace the computer cover; reconnect the computer and peripherals to electri-
cal outlets, and turn them on.
After the system completes the power-on self-test (POST) routine, it runs a mem-
ory 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 electrical outlets, remove the computer cover and memory
module, and check all the installed DIMMs to make sure they are seated properly
in their sockets. Then repeat steps 5 and 6.
The system detects that the new memory does not match the system configura-
tion information, which is stored in nonvolatile random-access memory (NVRAM).
The monitor displays an error message to that effect, ending with the following
words:
3UHVV)!WRFRQWLQXH)!WRHQWHU6\VWHP6HWXS
&75/!$/7!)!WRHQWHU8WLOLW\0RGH
7. Press <F2> to enter the System Setup program, and check the System Memory set-
ting in the system data box on either of the System Setup screens.
The system should have already changed the System Memory value to reflect
the newly installed memory.
If the total is incorrect, one or more of the DIMMs may not be installed properly.
Repeat this procedure, checking to make sure the DIMMs are firmly seated in
their sockets.
