A-Tech 4GB DDR4 2400MHz CL17 1.2V 260-Pin SODIMM Laptop RAM

4GB DDR4 2400MHz SODIMM upgrade

This single 4GB DDR4 module runs at 2400MHz with CL17 latency and standard 1.20V operation. It uses a 260-pin SO-DIMM form factor and unbuffered non-ECC architecture. The stick is built with major-brand chips and serves as a direct replacement for Crucial CT4G4SFS824A and CT2K4G4SFS824A part numbers. It targets laptop, notebook and all-in-one owners who need a straightforward capacity increase.

Check your laptop manual for DDR4 SO-DIMM support

Verify that your system accepts DDR4 SO-DIMM modules at 2400MHz and 1.20V before ordering. Confirm the maximum capacity per slot and the total number of available 260-pin slots in your chassis. This module is unbuffered and non-ECC, so it will not work in platforms that require registered or ECC memory. The product is sold as a single 4GB stick rather than a matched pair.

Low-voltage DDR4 keeps thermals modest

At 1.20V the module draws minimal power and produces little heat during typical workloads. Passive cooling from the laptop chassis is sufficient; no active fan or heatsink is attached to the stick. Silent operation is inherent because there are no moving parts on the memory itself. Power consumption remains low whether the system is idling or handling multitasking loads.
