Figure 5-5. Inserting Memory DIMMs
3. DIMMs are keyed so they can only be inserted one
way. Position the DIMM over the socket on the
board (Figure 5-5, A and B). The notches in the
bottom edge of the DIMM mates with the raised
bumps in the DIMM socket.
4. Press down evenly on the DIMM until it seats
correctly. The white levers on the sockets are not
"tools" to aid in the insertion, only to keep the
DIMM's in place and to aid in extraction. The levers
should click in place once the DIMM is fully
inserted.
5. Repeat the above steps to install any remaining
DIMMs.
6. Install the memory board back into the system as
described later in this chapter.
