Installing System Components

6 Align the memory module's edge connector with the alignment key on the memory module socket, and
insert the memory module in the socket.
NOTE:
The memory module socket has two alignment keys that allows you to install the memory module in
the socket in only one way.
7 Press down on the memory module with your thumbs while pulling up on the ejectors with your index
fingers to lock the memory module into the socket.
When the memory module is properly seated in the socket, the ejectors on the memory module socket
align with the ejectors on the other sockets that have memory modules installed.
8 Repeat step 3 through step 7 of this procedure to install the remaining memory modules.
9 Replace the memory cooling shroud. See "Installing the Cooling Shroud" on page 75.
NOTICE:
Never operate your system with the memory cooling shroud removed. Overheating of the system can
develop quickly resulting in a shutdown of the system and the loss of data.
10 Close the system. See "Opening the System" on page 55.
11 (Optional) Enter the System Setup program, and check the System Memory setting on the main
System Setup screen. See "Entering the System Setup Program" on page 37.
The system should have already changed the value to reflect the newly installed memory.
12 If the value is incorrect, one or more of the memory modules may not be installed properly. Repeat
step 2 through step 11 of this procedure, checking to ensure that the memory modules are firmly
seated in their sockets.
13 Run the system memory test in the system diagnostics. See "Running the System Diagnostics" on
page 136.
Removing Memory Modules
CAUTION:
Only trained service technicians are authorized to remove the system cover and access any of the
components inside the system. See your Product Information Guide for complete information about safety
precautions, working inside the computer, and protecting against electrostatic discharge.
1 Turn off the system, including any attached peripherals, and disconnect the system from the electrical
outlet.
2 Open the system. See "Opening the System" on page 55.
3 Remove the memory cooling shroud. See "Removing the Cooling Shroud" on page 74.
NOTICE:
Never remove the memory cooling shroud without first powering down the system. Overheating of the
system can develop quickly resulting in a shutdown of the system and the loss of data.
4 Locate the memory module sockets on the system board. See Figure 6-2.
CAUTION:
The DIMMs are hot to the touch for some time after the system has been powered down. Allow the
DIMMs to cool before handling them. Handle the DIMMs by the card edges, and avoid touching the DIMM
components.
