System-specific DDR4 SODIMM for Dell Latitude 14

This 8 GB module is built for Dell Latitude 14 models 5480, 5490 and E5470 that have two SODIMM slots. It runs at 2400 MHz with CL17 timing and 1.2 V unbuffered operation. The 260-pin form factor fits the factory memory socket directly.

Suited for single-slot upgrades on supported

Buyers who need ECC error correction or registered buffering should choose a different module. Systems limited to one memory slot or requiring a higher total capacity than 32 GB will not be served by this part.

Handles everyday workloads and moderate multitasking

The 8 GB stick adds headroom for office applications, web browsing and light content creation. Memory-intensive tasks such as virtualisation or large dataset processing will exhaust the 32 GB platform ceiling quickly.

Questions about this item

My Dell Latitude 14 5480 has two SODIMM slots — do I need to fill both for this 8 GB stick to work?

No, the 5480 supports single-channel operation. This 260-pin DDR4-2400 module runs at 1.2 V and will boot in either slot without a matching pair.

I still have the original 4 GB DDR4-2400 module in the second slot — will mixing ranks cause instability?

The original stick is typically 1Rx8; this kit is 2Rx8. Mixed ranks are supported on the 5480, 5490 and E5470 platforms, though the system will run in flex mode rather than full dual-channel.

After installing the module, how can I verify it is running at the rated 2400 MT/s and CL17 timings?

Open Task Manager → Performance → Memory and confirm Speed shows 2400 MHz. For timing details, run CPU-Z and check the SPD tab for 17-17-17 CAS latency.
