Dell XPS SODIMM upgrade

This OWC module is a 4 GB DDR3 SODIMM built to JEDEC PC3-10600 specifications. It runs at 1333 MHz with CL9 latency at 1.5 V and uses a 2Rx8 unbuffered, non-ECC design. The 204-pin form factor fits the memory slots of select Dell XPS laptops.

Suits listed XPS models only

The module is validated for Dell XPS 14 L401X, 14z L412z, 15 L502X and 15z L511z. Builders working on other laptop brands, desktop boards or servers should look elsewhere. Buyers who need ECC, registered DIMMs or a different DDR generation should look elsewhere. Anyone wanting a higher-capacity stick or a dual-rank configuration beyond 2Rx8 will need a different part.

204-pin DDR3 SODIMM form factor

The single physical specification that decides fit is the 204-pin DDR3 SODIMM interface. If the target system requires a different pin count, a DIMM form factor or another memory generation, this module will not install.

Questions about this item

Will the 204-pin SODIMM fit the memory slot in my Dell XPS 14 L401X?

Yes, the module uses the standard 204-pin DDR3 SODIMM form factor required by the XPS 14 L401X, XPS 14z L412z, XPS 15 L502X and XPS 15z L511z.

Do I need any tools or BIOS changes to install this 4GB DDR3 1333 module?

No tools are required; open the bottom access panel, align the notch on the 204-pin stick with the slot key, press firmly until the side clips click, then close the panel — the system detects the new memory automatically.

Does this non-ECC 1.5V module need any periodic maintenance or replacement?

No ongoing maintenance is needed; the JEDEC-standard DDR3 SODIMM is a solid-state component with no moving parts and is covered by OWC's limited lifetime warranty if a fault ever develops.
