5. Press 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 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. 6. When the SYSTEM MEMORY total is correct, press the 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 (and see Figure 6-7) to install a DIMM: 1. Locate the first empty socket in which you plan to install a DIMM. For optimum performance, DIMMs should be installed in consecutive sockets beginning with socket A. 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 running down the center of the socket until the securing tabs snap into place around the ends of the DIMM. securing clips 2. 1. Figure 6-7. Installing a 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). 2. 1.

> 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.

When the
SYSTEM MEMORY
total is correct, press
the <
ESC
> key to exit the System Setup program.

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 diagnos-
tics and troubleshooting any problems that may
occur.
Installing a DIMM
Use the following procedure (and see Figure 6-7) to
install a DIMM:
1.
Locate the first empty socket in which you plan to
install a DIMM.
For optimum performance, DIMMs should be
installed in consecutive sockets beginning with
socket A.
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.
Figure 6-7.

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).
