Before you install new memory modules, download the most recent BIOS for your computer from the Dell | Support website at support.dell.com.
Each memory socket on the system board must be occupied either by a RIMM or a CRIMM.
Memory Modules

RIMM

CRIMM
NOTICE: If you remove your original memory modules from the computer
during a memory upgrade, keep them separate from any new modules that you
may have, even if you purchased the new modules from Dell. You must install
your original memory modules in pairs either in connectors RIMM1 and
RIMM 2 or RIMM 3 and RIMM4. Do not pair one original memory module
with one new memory module. Otherwise, your computer may not start
properly.
Memory sockets must be upgraded in matched pairs. In other words, two sockets in a pair must contain modules of identical capacity, number of components, and speed. See "System Board Memory Components" to identify pairs of sockets.
Mixed pairs of ECC and non-ECC modules all function as non-ECC.
Be sure to install a RIMM in socket 1 first (closest to the processor) before installing modules in the other sockets.
NOTICE: Before disconnecting a device from the computer, wait 10 to 20
seconds after disconnecting the computer from its electrical outlet. Before
removing a component from the system board, verify that the standby power
light on the system board has turned off. To locate this light, see your
computer's illustration in "System Board Components."
Turn off the computer and devices, disconnect them from their
electrical outlets, and wait 10 to 20 seconds.
NOTICE: To avoid damage to the memory module, press the securing clips
with equal force applied at each end of the memory socket.
Press the securing clips at each end of the memory socket outward
simultaneously until the module pops out slightly from the socket.
NOTICE: If you remove your original memory modules from the computer
during a memory upgrade, keep them separate from any new modules that you
may have, even if you purchased the new modules from Dell. You must install
your original memory modules in pairs either in connectors RIMM1 and

with one new memory module. Otherwise, your computer may not start

NOTICE: Before you install a memory module, download the latest BIOS for
your computer from the Dell | Support website at support.dell.com.
If necessary, remove memory modules that occupy system board
sockets in which you plan to install upgrade modules.
Press the securing clips at each end of the socket outward until they
snap open.
Align the slots on the bottom of the module with the ridges inside the
socket.
NOTICE: To avoid damage to the memory module, press the module straight
down into the socket with equal force applied at each end of the module.
Press the module straight down into the socket until the securing clips
snap into place at the ends of the module. You should hear a click
when the module is correctly seated.
Reconnect the computer and devices to their electrical outlets, and
turn them on.
NOTE: If enabled, the
Chassis Intrusion option
will cause the following
message to be displayed
at the next computer
start-up: Alert!
Cover was
previously
removed.
The computer detects that the new memory does not match the existing computer configuration information and generates the following message:
The amount of system memory has changed. Strike the F1 key to continue, F2 to run the setup utility
Enter system setup, and check the value for System Memory. The
computer should have already changed the value of System Memory
to reflect the newly installed memory. If the new total is correct, skip to
step 9.
If the memory total is incorrect, repeat step 1 through step 3 in
"Removing a Memory Module." Check the installed modules to
ensure that they are seated properly in their sockets. Then repeat step
7 through step 9 in "Installing a Memory Module."
When the System Memory total is correct, exit system setup.
Run the Dell Diagnostics to verify that the memory modules are
operating properly.
