Note: If only one DIMM is used on the computer, the card must be installed in SLOT-0 ( a ), not in SLOT-1 ( b ).

Remove DIMM by gently spreading the socket connectors up and down as shown in the direction of the arrows and pull the DIMM out.

Insert the notched end of the DIMM into the socket.

Press the DIMM firmly, and pivot it until it snaps into the place.

Make sure that it is firmly fixed in the slot and does not move easily.
