Dell PowerEdge R660 Installation and Service Manual

Installing a memory module

Locate the appropriate memory module socket.
CAUTION: Handle each memory module only by the card edges, ensuring not to touch the middle of the memory module or metallic contacts.
If a memory module is installed in the socket, remove it.
NOTE:Ensure the socket ejector latches are fully open before installing the memory module.
Align the edge connector of the memory module with the alignment key of the memory module socket, and insert the memory module in the socket.
CAUTION: To prevent damage to the memory module or the memory module socket during installation, do not bend or flex the memory module; insert both ends of the memory module simultaneously.
NOTE:The memory module socket has an alignment key that enables you to install the memory module in the socket in only one orientation.
CAUTION:Do not apply pressure at the center of the memory module; apply pressure at both ends of the memory module evenly.
Press the memory module with your thumbs until the ejectors firmly click into place. When the memory module is properly seated in the socket, the levers on the memory module socket align with the levers on the other sockets that have memory modules installed.
Figure 1. Installing a memory module

Replace the air shroud.
Follow the procedure listed in After working inside your system.
To verify if the memory module has been installed properly, press F2 and navigate to System Setup Main Menu > System BIOS > Memory Settings. In the Memory Settings screen, the System Memory Size must reflect the updated capacity of the installed memory.
If the System Memory Size is incorrect, one or more of the memory modules may not be installed properly. Ensure that the memory modules are firmly seated in their sockets.
Run the system memory test in system diagnostics.
