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
7. Press <F2> to enter the System Setup program,
and check the System Memory category in the
lower-right corner of Page 1.
The system should have already changed the value in
the System Memory category to reflect the newly
installed memory. Verify the new total.
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
check the installed DIMMs to make sure that they are
seated properly in their sockets. Then repeat steps 4
and 5.
8. When the System Memory total is correct, press
the <Esc> key to exit the System Setup program.
9. Run the Dell diagnostics to verify that the
DIMMs are operating properly.
See your Diagnostics and Troubleshooting Guide for
information on running the diskette-based diagnostics
and troubleshooting any problems that may occur.
Installing a DIMM
Use the following procedure to install a DIMM:
1. Locate the first empty socket in which you plan to
install a DIMM.
DIMMs should be installed in consecutive sockets
beginning with socket A for optimum performance.
2. Locate the plastic securing clips at each end of the
socket. Press the clips outward until they snap
open.
3. Orient the DIMM to the socket by aligning the
notches in the DIMM’s edge connector with the
crossbars in the socket.
4. Press the DIMM straight into the slot running
down the center of the socket (see Figure 6-7)
until the securing clips snap into place around the
ends of the DIMM.

Removing a DIMM
To remove a DIMM, press the securing clips outward
(see Figure 6-8) simultaneously until the DIMM dis-
engages from the socket (it should pop out slightly).
