16GB DDR4 2400MHz SODIMM

This is a 16GB DDR4 2400MHz CL17 260-pin SODIMM laptop memory module from A-Tech. It operates at 1.20V as an unbuffered, non-ECC stick designed for notebook and all-in-one upgrades. The module is built as a compatible replacement for the Kingston K821PJ-MIDS17475QWAF part number.

Who this suits and who should look elsewhere

This module suits owners of laptops or all-in-one PCs that accept a single 16GB DDR4 2400MHz SO-DIMM with CL17 timing and 1.20V operation. Buyers needing ECC error correction, registered buffering, a different voltage, a higher speed grade, or a DIMM form factor for desktop motherboards should look elsewhere.

The specification that decides fit

The decisive specification is the 260-pin DDR4 SO-DIMM form factor combined with DDR4 2400 (PC4-19200) speed and CL17 latency at 1.20V; your system must support this exact combination for the module to work.

Questions about this item

How do I verify the module is running at 2400 MHz CL17 after installation?

Open Task Manager or a hardware monitor such as CPU-Z; the memory tab should show 2400 MHz speed and CAS latency 17 for the new SODIMM.

What comes in the package and do I need any extra parts?

The box contains one 16 GB 260-pin DDR4 SODIMM; no cables, tools or additional components are required for installation.

Which capacity should I choose if my laptop has a single memory slot?

This listing is a single 16 GB module, so it fills one slot and provides the full 16 GB upgrade in one step.
