Dell Latitude 5440 and 5540 memory kit

This 16GB kit contains two 8GB DDR4 SODIMM modules built for Dell Latitude 5440 and 5540 laptops. It runs at 3200MHz with CL22 latency and 1.2V operation. The unbuffered, non-ECC design matches the factory specification for these mobile workstations.

Simple SODIMM installation

Most owners can swap modules in minutes by opening the memory door and pressing the sticks into the 260-pin slots until they click. The only common issue is failing to seat both modules fully, which leaves the system seeing only 8GB or failing to boot.

DDR4 SODIMM platform limits

The DDR4 SO-DIMM interface caps bandwidth at the JEDEC PC4-25600 rate used here. Systems that require ECC, registered DIMMs or higher voltages cannot use this kit. Buyers needing more than 16GB must verify their laptop supports larger capacity modules.

Questions about this item

How can I verify the kit is running at 3200 MHz and CL22 after installing it in my Latitude 5440?
