5. Open both latches of the memory module socket 1, and insert the
memory module into the socket 2.
Installing a DIMM
✎
A memory module can be installed in only one way. Match the notch
on the module with the tab on the memory socket.
✎
If you have one preinstalled DIMM in socket XMM1 and are adding
a second DIMM, it is recommended that you install an identical
DIMM into the XMM2 socket. If you are populating all four DIMM
sockets, use identical DIMMs in each socket. Otherwise, the system
will not operate in dual channel mode.
6. Push the module down into the socket, ensuring that the module
is fully inserted and properly seated. Make sure the latches are in
the closed position 3.
7. Repeat steps 5 and 6 to install any additional modules.
8. Replace the front bezel and computer access panel. Refer to
“Reassembling the Computer.”
The computer automatically recognizes the additional memory the
next time you power on the computer.
