4 GB DDR4 2400 SO-DIMM Laptop Upgrade

This 4 GB DDR4 2400 MHz SO-DIMM module uses 260-pin DDR4 technology at 1.2 V with CL17 latency. It is an unbuffered, non-ECC memory stick built with major-brand chips and tested for reliability. The kit targets owners of compatible laptops, notebooks and all-in-one systems who want a straightforward capacity increase.

Suits single-slot 4 GB DDR4 2400 upgrades only

Buyers whose laptops accept a single 260-pin DDR4 2400 SO-DIMM at 1.2 V and CL17 can install this module directly. Systems that require ECC, registered DIMMs, a different DDR generation, higher speeds, lower latency or larger single-module capacities should look elsewhere.

260-pin DDR4 2400 SO-DIMM form factor decides fit

The 260-pin SO-DIMM outline, DDR4 signalling and 2400 MHz rating are the sole physical and electrical interface. If the service manual or BIOS specifies a different pin count, generation or speed grade, the module will not seat or function. Confirm those three parameters before ordering.

Questions about this item

Will the 260-pin DDR4 SO-DIMM fit my laptop's memory slot?

Yes, this module uses the standard 260-pin DDR4 SO-DIMM form factor used by most laptops and all-in-one systems that support DDR4 2400 memory.

What is the correct way to seat the module so it is detected on first boot?

Align the notch with the slot key, insert at a slight angle, then press down firmly until both side clips click into the notches on the module edges.

Does the 1.20V unbuffered non-ECC design require any future firmware updates or component swaps?

No, the module has no firmware and no user-serviceable parts; it runs at standard DDR4 voltage and is designed to last the usable life of the laptop.
