Figure 2-10Installing a DIMM

NOTE A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket.

A DIMM must occupy the XMM3 socket. Always populate XMM3 before XMM1, and XMM4 before XMM2 (populate the black sockets before white sockets in each channel).

In order to create a dual-channel memory configuration, the memory capacity of XMM4 must equal the memory capacity of XMM3 (and XMM2 must equal XMM1, if used). Refer to Populating DIMM Sockets for more information.

12.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).

13.Repeat steps 11 and 12 to install any additional modules.

14.Replace the access panel.

15.If the computer was on a stand, replace the stand.

16.Reconnect the power cord and any external devices, then turn on the computer. The computer should automatically recognize the additional memory when you turn on the computer.

17.Lock any security devices that were disengaged when the access panel was removed.
