Performing a Memory Upgrade
Follow this procedure to perform a memory upgrade:
1.
Remove the computer cover according to the
instructions in “Removing the Computer Cover”
in Chapter 5.
2.
Rotate the power supply out of the way according
to the instructions in “Rotating the Power Supply
Away From the System Board” in Chapter 5.
3.
Determine the DIMM sockets into which you will
install SIMMs or replace existing DIMMs.
See Figure 6-1 and Table 6-1.
4.
Install or replace DIMMs as necessary to reach
the desired memory total.
Follow the instructions in “Installing a DIMM” or
Removing a DIMM,” as appropriate, found later in
this section.
5.
Rotate the power supply back into the computer
chassis.
6.
Replace the computer cover, reconnect your com-
puter and peripherals to their power sources, and
turn them on.
After the system completes the power-on self-test
(POST) routine, the system runs a memory test that
displays the total memory of all installed DIMMs,
including those you just installed.
NOTE: If the memory total is incorrect, turn off your
computer and peripherals and disconnect them from
their power sources, remove the computer cover, and
make sure that the installed DIMMs are seated prop-
erly in their sockets. Then repeat this step.
