Compatible Dell Latitude 14 upgrade

This 16GB DDR4 SO-DIMM module is built for Dell Latitude 14 models 5480, 5490 and E5470 that have two memory slots. It runs at 2400MHz with CL17 timing and 1.2V operation. The single stick uses a 260-pin unbuffered non-ECC design.

Suits single-slot expansion, not max-capacity builds

Buyers adding one module to an empty slot or replacing a smaller stick will reach 16GB or 24GB total. Systems already populated with two 16GB modules cannot accept this kit. The 32GB ceiling on these models means a second 16GB stick would be the final upgrade.

260-pin DDR4 2400MHz CL17 specification

The module delivers PC4-19200 bandwidth with 17-17-17 latency at 1.2V. Major-brand chips are configured as 2Rx8. Verify the laptop has a free SO-DIMM socket before purchase.

Questions about this item

How much power does the 1.2 V DDR4 2400 SODIMM draw when the laptop runs all day?

At 1.2 V the module follows standard DDR4 low-voltage operation; actual draw depends on the Dell Latitude 5480, 5490 or E5470 memory controller and workload.

What must the Dell Latitude 14 already have so this 260-pin stick installs and works?

The laptop needs a free DDR4 SODIMM slot — the 5480, 5490 and E5470 each provide two sockets supporting up to 32 GB total.

Will this CL17 2400 MHz module run stably beside the original memory in a Latitude E5470?

Yes — the BIOS will match both sticks to the slowest common speed and latency, so the original and this 16 GB kit operate together at 2400 MHz CL17.
