System-specific DDR3 upgrade for Dell OptiPlex

This OWC module adds 4GB of DDR3 1600 memory to a Dell OptiPlex XE2 SFF or XE2 Tower. It is a JEDEC-standard, non-ECC UDIMM that installs in a standard 240-pin desktop slot. The single rank 1Rx8 design runs at 1.5V with CL11 latency. It targets owners of those specific OptiPlex models who want a straightforward capacity increase.

Suits XE2 SFF and Tower owners.

The part is validated only for the Dell OptiPlex XE2 SFF and XE2 Tower. It will not help builders working on a different motherboard platform, a laptop, or any system that requires ECC or registered modules. Buyers with a different OptiPlex series or a workstation needing error correction should look elsewhere.

240-pin DDR3 UDIMM form factor decides fit

The module uses the 240-pin DDR3 UDIMM form factor, which physically matches the memory slots in the compatible OptiPlex XE2 systems. A motherboard that accepts only a different pin count, a different DDR generation, or a registered DIMM type cannot use this module. Verify the slot type before ordering.

Questions about this item

Will the 240-pin DDR3 UDIMM fit the Dell OptiPlex XE2 SFF chassis?

Yes, the 240-pin DDR3 UDIMM is the correct form factor for the Dell OptiPlex XE2 SFF and Tower systems listed in the compatibility data.

What is the correct way to seat the module so the clips lock on both ends?

Align the notch on the module with the slot key, press straight down firmly until both side clips snap into place with an audible click.

Does the module require any firmware updates or driver installation after fitting?

No firmware or driver is needed; the system BIOS detects the 4GB DDR3 1600 CL11 module automatically on first boot.
