16 GB DDR4 SODIMM for Dell Latitude

This 16 GB DDR4 2400 MHz CL17 SODIMM is built for Dell Latitude 5490, 5495, 5580, 5590 and 7290 laptops. It uses a 260-pin unbuffered non-ECC design at 1.2 V. The module meets JEDEC and RoHS standards for a warranty-safe upgrade.

Replaces factory memory in listed Latitude models

Upgrading from the original 4 GB or 8 GB modules to this 16 GB stick adds headroom for multitasking and larger workloads. The jump is worthwhile when the system supports a single 16 GB module and the current memory limits open applications.

Verify slot count and maximum per slot

Check the service manual for your specific Latitude model to confirm the number of SODIMM slots and the maximum capacity each slot accepts. Ensure the BIOS is current and that the existing module matches the DDR4 2400 specification for best compatibility.

Questions about this item

Will the 260-pin SODIMM fit the memory slot in a Dell Latitude 5490?

Yes, the 260-pin DDR4 SODIMM form factor matches the slot used in the Latitude 5490, 5495, 5580, 5590 and 7290.

What is the correct way to seat this module, and where do people go wrong?

Align the notch on the module with the key in the slot, insert at an angle until the contacts are fully hidden, then press down evenly until both retention clips snap into place; the common error is pressing one side before the other, which leaves the module partially seated.

Does this 16GB DDR4 2400MHz CL17 module require any firmware updates or periodic replacement?

No firmware updates are needed for the memory itself; it is a passive component with no moving parts and no scheduled replacement interval.
