4GB DDR4 3200MHz SODIMM for Laptops

This 4GB DDR4 SO-DIMM runs at 3200MHz with CL22 latency and 1.20V operation. It uses a 260-pin form factor and unbuffered, non-ECC architecture. Major brand chips provide reliable performance for compatible laptop and all-in-one systems.

Who this suits and who should look elsewhere

Suits owners of DDR4 laptops needing a single 4GB replacement matched to the Crucial CT4G4SFS632A part. Builders requiring higher capacity per slot, dual-channel kits, ECC error correction, or lower CAS latency should consider other modules.

The specification that decides fit

The 260-pin DDR4 SO-DIMM interface at 3200MHz PC4-25600 speed determines compatibility. Your system must accept DDR4 SO-DIMM memory at this voltage and pin count for the module to function correctly.

Questions about this item

Will this 260-pin DDR4 SODIMM fit my laptop's memory slot?

The module uses the standard 260-pin DDR4 SO-DIMM form factor and 1.20V voltage required by most laptop slots.

How do I install the module and which step is often missed?

Power off the laptop, open the access panel, align the notch on the 260-pin edge connector, press firmly until the side clips click, then verify 3200MHz speed in BIOS.

Will the 3200MHz CL22 memory need any firmware updates or replacement later?

No firmware updates are required for the DDR4 SODIMM; it is tested for lifetime reliability and runs at standard 1.2V without degradation.
