5.Orient the DIMM so that the cutouts on its edge connector align with the cross- bars in the central groove of the socket.

NOTICE: Do not press near the middle of the DIMM. Doing so could break the module.

6.Insert the DIMM straight down into the socket, making sure that it fits into the vertical guides at each end of the socket.

Press firmly at each end until the DIMM snaps into place (see step 2 of Figure 2-11).

If you inserted the DIMM correctly, the securing clips snap into the cutouts at each end of the DIMM (see step 3 of Figure 2-11).
