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.

module evenly.
4. 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.
