Figure 8-1 shows the general location of the DIMM sockets on the system board.
Figure 8-4 shows the order of the DIMMs sockets.
3. Install or replace the DIMMs as necessary to reach the desired memory total
(see “Installing DIMMs” or “Removing DIMMs” found later in this chapter).
4. Close the computer doors, reconnect the system to the electrical outlet, and turn
on the system. After the system completes the power-on self-test (POST) rou-
