Prerequisites
Follow the safety guidelines listed in the Safety instructions.
Follow the procedure listed in the Before working inside your system
Power off the system and all attached peripherals.
Disconnect the system from the electrical outlet, and disconnect the peripherals.
Lay the system on its side.
Remove the system cover.
NOTE: The memory modules are hot to touch for some time after the system has been powered down. Allow the memory modules to cool before handling them. Handle the memory modules by the card edges and avoid touching the components or metallic contacts on the memory module.
Removing memory modules:
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.
To release the memory module from the socket, simultaneously press the ejectors on both ends of the memory module socket.
Lift the memory module away from the chassis.
Installing memory modules:
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.
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.
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.
NOTE: The alignment key allows 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 socket levers firmly click into place.
Install the system cover.
Place the system upright on its feet on a flat and stable surface.
Reconnect the peripherals and connect the system to the electrical outlet.
Turn on the system, including any attached peripherals.
Press F2 to enter System Setup, and check the System Memory setting.
The System Memory Size should reflect the installed memory.
If the value is incorrect, one or more of the memory modules may not be installed properly. Ensure that the memory modules are firmly seated in the sockets.
Run the system memory test in system diagnostics.
