DIMM Installation

To reinstall memory circuits, hold the DIMM upright over its socket. Make sure the keying holes and notches are in their proper positions. Gently push the DIMM board into the socket, so that the board snaps into place under the locking retainer on each side of the socket. Be sure that the retainers mate tightly with DIMM board notches. Do not force a DIMM into its socket!
