1. Shut down the system, including any attached peripherals, and disconnect the
system from the electrical outlet.
2. Open the panel doors on top of the computer.
See “Accessing the Interior of Your System” in Chapter 7.
3. Holding the memory board by the upper corners, pull the board out of the system
and place it on an antistatic surface.
4. Locate the DIMM sockets in which you will install or replace DIMMs.
Figure 8-5 shows the relative location of the DIMM sockets on the memory
board.
5. Install or replace the DIMMs as necessary to reach the desired memory total.
6. Replace the memory board.
With the DIMM sockets facing the microprocessors, align the connectors on the
board with the corresponding connectors on the system board. Press the board
carefully but firmly into place.
7. Close the panel doors, reconnect the system to the electrical outlet, and turn on
the system.
After the system completes the power-on self-test (POST) routine, it runs a mem-
ory test that displays the new memory total.
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 that ends with the following
words:
8. Press <F2> to enter the System Setup program, and check the
System Memory
field on the System Setup screens. The system should have already changed the
value in the
System Memory
field to reflect the newly installed memory. If the
value is incorrect, one or more of the DIMMs may not be installed properly.
Repeat steps 1 through 7 again, checking to make sure that the DIMMs are firmly
seated in their sockets.
9. Run the system memory test in the Dell Diagnostics.
To install a DIMM, perform the following steps:
1. Press down and outward on the ejectors on the DIMM socket, as shown in
Figure 8-6, to allow the DIMM to be inserted into the socket.
