4GB DDR4 2400MHz SO-DIMM module

This 4GB DDR4 2400MHz CL17 1.2V 260-Pin SO-DIMM module is built for laptop, notebook, and all-in-one systems that accept DDR4 memory. It is a non-ECC unbuffered stick designed to increase capacity for everyday workloads.

Check DDR4 SO-DIMM slot and speed support

Verify that your system uses DDR4 SO-DIMM slots and supports 2400MHz operation at 1.2V. Confirm the maximum memory per slot and total capacity allowed by the manufacturer before ordering this 260-pin module.

Suits capacity upgrades on DDR4 laptops

This single 4GB stick suits users adding memory to a compatible DDR4 laptop or all-in-one. Buyers who need ECC, registered modules, higher frequencies, or larger single-module capacities should look at other options.
