Dell Latitude E5440 memory upgrade

This 4 GB DDR3L 1600 MHz SODIMM is built for the Dell Latitude 14 5000 Series (E5440). It runs at 1.35 V with CL11 11-11-11 timings in an unbuffered 1Rx8 layout. The 204-pin module installs directly into the notebook slots. One stick is supplied in the package.

Suitable for Latitude E5440 owners adding capacity

The single 4 GB stick works in systems with two slots supporting up to 16 GB total. It is not ECC registered, so it will not serve workstations that require error-correcting memory. Buyers needing higher density per slot or a different voltage should look elsewhere.

1.35 V DDR3L voltage requirement

The module operates at 1.35 V, the defining spec for DDR3L compatibility in this notebook. A standard 1.5 V DDR3 part will not meet the platform requirement. Confirm the slot accepts low-voltage DDR3L before purchase.

Questions about this item

What slot and pin count does this module use for the Dell Latitude 14 5000 Series (E5440)?

It uses a 204-pin DDR3L SO-DIMM slot, which is the standard memory socket on the Latitude E5440.

How is the 4GB DDR3L 1600MHz stick installed, and what step is often missed?

Power off the notebook, remove the battery, open the memory door, insert the module until seated, then press down until the side clips lock; the step often missed is reinserting the battery before powering on.

What maintenance or replacement will this memory need during the laptop's life?

No routine maintenance is required; replacement is only needed if a fault appears or if you later upgrade to the 16 GB maximum supported across the two sockets.
