IMPORTANT: You replace the existing memory modules, not adding to them. Be sure that you follow all module handling precautions as indicated by Dell. Mishandling memory modules can render them unusable due to static discharge or other damage that is incurred through improper insertion.
Upgrading the memory requires that you do the following:
Turn off the computer and disconnect the system from the electrical outlet.
Let the computer cool down for 5-10 minutes (memory modules can be hot to the touch right after turn off).
Gain access to the top of the computer so that you can remove the top panel and cooling shroud from the interior compartment. You may need to un-rack the computer or slide it out if it's mounted on slide rails.
Carefully follow the instructions that are provided in the owner's manual to:
Gain access to the memory modules.
Remove the existing modules.
Insert the new modules.
Verify that the operating system recognizes new modules.
The memory modules that you replace are obvious by their physical appearance. Non-used slots are populated with the blank modules that feature a plastic trim piece along the top. Leave these in place! The actual memory modules do not have the trim pieces. The red arrows in the following images indicate the memory modules that you replace.
Memory module orientation is reversed for some of the slots- if the module does not readily insert, reverse its orientation, and try again. DO NOT FORCE THE MODULES INTO PLACE!
After you replace the memory modules, replace the cooling shroud and top panel, and plug the unit back into the electrical outlet. Follow the instructions in the manual to verify that the memory is properly recognized.
