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 should install your new memory modules in connectors DIMM3 and DIMM4. If possible, do not pair an original memory module with a new memory module. Otherwise, your computer may not function at optimal performance.
