Installing System Board Options 6-5
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. Determine the DIMM sockets into which you will
install SIMMs or replace existing DIMMs.
See Table 6-1.
3. 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.
4. 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.
The system detects that the new memory does not
match the existing system configuration information,
which is stored in nonvolatile random-access mem-
ory (NVRAM), and generates the following
message:
The amount of system memory has
changed.
Strike the F1 key to continue, F2 to
run the setup utility

NOTES: For optimum performance, install DIMMs in con-
secutive sockets starting with socket A, as shown in the pre-
ceding table.
The preceding table is not a complete list of all valid DIMM
configurations.
CAUTION: See “Protecting Against Electro-
static Discharge” in the safety instructions at
the front of this guide.
