System-specific SODIMM for Dell Latitude

This 4 GB DDR4 module is built to the exact electrical and physical requirements of the Dell Latitude 15 5580, 5590 and E5570. It arrives as a single unbuffered, non-ECC stick using 260-pin SO-DIMM packaging and major-brand components. The 1.2 V operating voltage matches the platform specification.

Suitable for capacity upgrades within supported

The kit suits owners of the listed Latitude models who need to add or replace memory up to the platform maximum of 32 GB across two sockets. Buyers whose systems require ECC, registered modules or a different pin count should select a different part. Machines outside the three named models are not guaranteed compatible by the manufacturer.

2400 MHz DDR4 speed rating

The module runs at DDR4 2400 (PC4 19200) with CL17 17-17-17 timings and a 2Rx8 organisation. This speed grade determines whether the memory will operate at its rated frequency or be down-clocked by the memory controller. Verify the platform supports DDR4 2400 before purchasing.

Questions about this item

Should I choose the single 4 GB stick or add a second module to reach the 32 GB maximum?

The module is a single 4 GB stick; the Latitude 15 5580, 5590 and E5570 each have two SODIMM slots and support up to 32 GB total, so you can add a matching stick later if you need more capacity.

What does the 2400 MHz rating actually deliver in these laptops?

The memory runs at DDR4-2400 (PC4-19200) with CL17 timing at 1.2 V, giving the rated bandwidth and latency the platform expects without overclocking.

Will the 260-pin DDR4 SODIMM interface work in my Latitude 15 5580, 5590 or E5570?

Yes — the 260-pin DDR4 SO-DIMM form factor, non-ECC unbuffered design and 1.2 V operation match the memory slots in all three Latitude 15 models listed.
