Targeted upgrade for Dell Latitude 15

This 16 GB DDR4 SODIMM is built for Latitude 15 models 5580, 5590 and E5570. It serves owners who need a single-module memory increase for those specific laptops. Buyers with other Dell models or non-DDR4 platforms cannot use this part.

Speed and form factor decide fit

The module runs at DDR4 2400 (PC4 19200) with CL17 timing in a 260-pin SO-DIMM package. Only systems that accept this exact speed, pin count and voltage will recognise the memory.

Low voltage keeps thermals simple

Operating at 1.2 V without a heat spreader, the unbuffered stick adds minimal heat and draws little power in normal laptop workloads. Passive cooling inside the chassis is sufficient for typical use.

Questions about this item

What does the 16 GB capacity mean for a Dell Latitude 15 5580?

A single 16 GB module fills one of the two SODIMM slots, giving you 16 GB total or 32 GB if you add a matching second stick.

How does the DDR4 2400 (PC4 19200) rating affect real-world speed?

The module runs at 2400 MT/s with CL17 timing; the laptop’s memory controller will set the final operating frequency, which may be 2133 MT/s on some Latitude 15 models.

Will the 260-pin SO-DIMM fit the Latitude 15 E5570 without modification?

Yes, the 260-pin DDR4 SO-DIMM form factor matches the factory slot exactly and requires no adapters or brackets.
