Single 4GB DDR4 SODIMM for laptop upgrades

This Crucial module delivers 4GB of DDR4 memory at 2400 MT/s with CL17 latency. It uses a 260-pin SO-DIMM form factor and operates at 1.20V. The stick is unbuffered, non-ECC, and built with a single-rank x8 organisation.

Suits one-slot notebooks needing a basic capacity

Ideal for older laptops with a single free DDR4 slot that only require 4GB extra for web browsing and office tasks. Not suited for dual-channel configurations, systems that demand higher frequencies, or workloads needing 8GB or more per module.

Speed rated at DDR4 2400 (PC4-19200)

The 2400 MT/s rating is the key compatibility figure; the module will down-clock if the platform only supports 2133 MT/s. Verify that the laptop accepts 260-pin DDR4 SO-DIMMs before purchase.

Questions about this item

Does this 260-pin DDR4 SO-DIMM fit the SODIMM slot in my laptop?

The module uses the standard 260-pin DDR4 SO-DIMM form factor, so it fits any laptop slot built for DDR4 memory.

What is the correct way to seat the module so the 1.20 V connection is solid?

Insert the stick at roughly a 30-degree angle, press down until the side clips click, and verify the notch aligns with the key in the slot.

When should I consider replacing this 4 GB CL17 stick?

Replace it if the laptop fails memory diagnostics, shows repeated crashes, or you need more capacity than 4 GB provides.
