Targeted upgrade for three Latitude models

This 4 GB DDR4 SODIMM is built specifically for Dell Latitude E5270, E5470 and E5570 laptops. It runs at 2133 MHz with CL15 latency and 1.2 V operation, matching the factory memory specification for those systems. The module is non-ECC, unbuffered and uses a single 1Rx8 rank.

Ideal for owners of the listed notebooks.

The part is validated only for the three Dell models above, so buyers with different laptops, desktops or servers should look elsewhere. It also does not suit users who need ECC error correction, registered buffering or capacities beyond 4 GB per slot.

Fits a standard 260-pin DDR4 slot

Installation uses the existing memory bay in each Latitude chassis, freeing no additional space but leaving other slots available for a second module. The JEDEC-compliant design means the system recognises the stick automatically without BIOS changes or special drivers.

Questions about this item

Which Dell Latitude models accept this 260-pin DDR4 SODIMM?

The module is validated for the Latitude E5270, E5470 and E5570. Each system uses the same DDR4 2133 SODIMM slot, so the stick fits any of the three.

Will the CL15 timing downclock automatically if my Latitude runs memory at a lower speed?

Yes. JEDEC-compliant DDR4 modules negotiate the highest common speed with the platform, so the stick will run at the native bus rate of your E5270, E5470 or E5570.

How do I confirm the 4 GB stick is recognised at 2133 MHz after installation?

Open Task Manager > Performance > Memory or run CPU-Z; both show total capacity, speed (2133 MHz) and CAS latency (CL15) for the new SODIMM.
