16GB DDR5 4800 SODIMM for Laptop Upgrade

This A-Tech module delivers 16GB of DDR5 memory at 4800MHz with CL40 latency and 1.10V operation. The 262-pin SO-DIMM form factor fits standard laptop and all-in-one slots. It is an unbuffered, non-ECC design built as a compatible replacement for Samsung M425R2GA3BB0-CQK.

Suits DDR5 Laptop Slots Only

This module works with systems that accept DDR5 SO-DIMM memory running at 4800MHz. Buyers whose laptops require DDR5 at a different speed or voltage should verify compatibility before ordering. It is not suitable for desktops or any device that uses a different pin count or memory generation.

262-Pin DDR5 SO-DIMM Form Factor

The 262-pin DDR5 SO-DIMM interface is the single specification that determines fit. If your system calls for this exact pin layout and DDR5 technology, the module will seat correctly; otherwise it will not install.

Questions about this item

My laptop uses a 262-pin SODIMM slot — does this module fit?

Yes — the stick is a 262-pin DDR5 SO-DIMM built to the standard laptop form factor.

Will the 1.1V voltage work with my existing DDR5 memory running at the same voltage?

It operates at 1.1V, the standard DDR5 voltage, so it matches other DDR5 modules that also run at 1.1V.

How can I confirm the CL40 timing is active after I install it?

Open Task Manager or a tool like CPU-Z and check the reported CAS latency; it should show CL40 at 4800MHz.
