5. 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.
NOTES: The value of
SYSTEM MEMORY
is given in
kilobytes. To convert kilobytes to megabytes, divide the
kilobyte total by 1024.
If the memory total is incorrect, turn off your com-
puter 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.
6. When the
SYSTEM MEMORY
total is correct, press the
<
ESC
> key to exit the System Setup program.
7. 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 (see Fig-
ure 6-7):
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 down into the slot run-
ning down the center of the socket until the
securing tabs snap into place around the ends of
the DIMM.

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