Dell Latitude 14 and 15 upgrade

This 16 GB DDR4 SO-DIMM is built for Dell Latitude 14 (3480, 7490) and 15 (3580) notebooks. It suits owners who need the maximum single-module capacity these platforms accept.

Simple slot insertion, no tools

The unbuffered, non-ECC stick plugs into a 260-pin DDR4 socket at 1.20 V. Mixing with existing modules is possible but the system will run at the slowest installed speed or CPU limit. A 64-bit operating system is required to address more than 4 GB.

Verify socket count and OS first

These laptops provide two SO-DIMM sockets and support up to 32 GB total. Confirm your model number matches 3480, 7490 or 3580 and that a 64-bit OS is installed before ordering.

Questions about this item

How do I verify the 2400 MHz DDR4 SO-DIMM is running at its rated speed after installation?

Enter the system BIOS or use a tool like CPU-Z to confirm the memory frequency reads 2400 MHz and the timings show 17-17-17 at 1.20V.

What is included in the package and do I need any extra parts for my Dell Latitude 14 3480?

The box contains one 16 GB 260-pin DDR4 SO-DIMM module; no additional components are required for installation.

Should I choose the single 16 GB stick or add a second one to reach the 32 GB maximum on my Latitude 15 3580?

The laptop supports two SO-DIMM slots up to 32 GB total; adding a second identical 16 GB stick enables dual-channel performance.
