4GB DDR4 SO-DIMM for Dell Latitude

This 4GB DDR4 2400 module uses a 260-pin SO-DIMM form factor with CL17 timing and 1.2V operation. It is built as a single 2Rx8 unbuffered stick without a heat spreader. The part is intended for owners of Dell Latitude 3490, 3590 or 5290 laptops who need a straightforward memory upgrade.

Check slot count and maximum memory

The compatible Latitude models listed have two memory sockets and support up to 32GB total capacity. Verify how many slots your unit currently has populated before ordering. Ensure the system runs DDR4 SO-DIMM memory and that the existing modules match the 2400 speed grade for best stability.

Unbuffered stick with major-brand chips

The module uses major-brand chipset components and carries no heat spreader, keeping the profile low for tight laptop chassis. A 260-pin edge connector aligns with the standard DDR4 SO-DIMM socket. Computer Memory Solutions guarantees compatibility with the listed Dell models and provides a limited lifetime warranty against manufacturing defects.

Domande su questo articolo

Does the CM512642400SO box contain only the 4 GB DDR4 2400 SO-DIMM or are tools or cables included?

The package includes one 260-pin DDR4 2400 CL17 2Rx8 SO-DIMM module; no tools, cables or additional components are supplied.

Should I choose the single 4 GB stick or a larger kit for my Dell Latitude 3490, 3590 or 5290?

This listing is a single 4 GB stick; the platforms support up to 32 GB across two sockets, so add a second matching module if you need more capacity.

What does the DDR4 2400 (PC4 19200) rating mean once the module is installed in a Latitude 3490?

It will run at 2400 MHz with CL17 timing at 1.2 V as non-ECC unbuffered memory, provided the system’s memory controller supports that speed.
