You will need to reset the chassis intrusion detector.

The computer detects that the new memory does not match the existing 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

5Press <F2> to 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. Verify the new total. If it is correct, skip to step 7.

6If the memory total is incorrect, turn off and disconnect your computer and devices from their electrical outlets. Open the computer cover, and check the installed DIMMs to make sure that they are seated properly in their sockets. Then repeat steps 3, 4, and 5.

7Reset the chassis intrusion detector by changing Chassis Intrusion to Enabled or Enabled-Silent.

NOTE: If a setup password has been assigned by someone else, contact your network administrator for information on resetting the chassis intrusion detector.

8When the System Memory total is correct, press <Esc> to exit system setup.

9Run the Dell Diagnostics to verify that the memory modules are operating properly.

Removing DIMMs

CAUTION: Before you perform this procedure, see the precautions in “Safety First—For You and Your Computer.”

NOTICE: To avoid damage to the memory module, press the securing clips with equal force applied at each end of the socket.

To remove a DIMM, press the securing clips at each end of the socket outward simultaneously until the DIMM pops out slightly from the socket.
