If the module is difficult to remove, gently ease the module back and forth to remove it from the connector.

NOTICE: Do not install ECC memory modules.

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™. If possible, do not pair an original memory module with a new memory module. Otherwise, your computer may not start properly. The recommended memory configurations are: A pair of matched memory modules installed in DIMM connectors 1 and 2 or a pair of matched memory modules installed in DIMM connectors 1 and 2 and another matched pair installed in DIMM connectors 3 and 4.

NOTE: If you install mixed pairs of PC3-8500 (DDR3 1066-MHz) and PC3-10600 (DDR3 1333-MHz) memory, the modules function at the speed of the slowest module installed.
