16GB DDR5 SODIMM for laptops

This 16GB DDR5 module uses the 262-pin SO-DIMM form factor and runs at 4800MHz with CL40 latency. It operates at the standard 1.10V DDR5 voltage and is unbuffered, non-ECC memory designed for laptop, notebook and all-in-one upgrades. The stick is a compatible replacement for Corsair CMSX16GX5M1A4800C40 and CMSX32GX5M2A4800C40 modules.

Capacity and headroom

A single 16GB module doubles the memory of many 8GB factory configurations and supports everyday multitasking, office suites and browser-heavy workflows. It leaves one slot free on typical two-slot laptops for a future 32GB total upgrade. Systems limited to one slot or workloads such as video editing, virtualisation or large datasets will exceed the usable headroom of a single module.

Thermals noise and power

With no heat spreader and a low 1.10V operating voltage, the module runs cool inside thin chassis designs and draws minimal power from the battery. Passive cooling is silent by nature, adding no fan noise to the system. The standard DDR5 voltage keeps thermal output low during sustained workloads, helping maintain laptop surface temperatures.

Questions about this item

Will this DDR5 4800 CL40 1.10V SODIMM run correctly alongside an existing DDR5 4800 module I want to keep?

Both modules must share the same DDR5 4800 speed, 1.10V voltage, CL40 latency and 262-pin form factor; mixing different specifications can cause instability or force the system to run at the lowest common settings.

How can I verify the 16GB DDR5 4800 module is detected at its rated 4800MHz speed after installation?

Open Task Manager on Windows or run dmidecode on Linux and confirm the memory shows 16GB capacity, DDR5 type, 4800 MT/s speed and 1.1V operating voltage.

Does the package include only the single 16GB 262-pin SODIMM or are any tools or extra parts supplied?

The box contains one 16GB DDR5 4800 CL40 1.10V 262-pin SODIMM module; no screwdriver, thermal pad or additional hardware is included.
