32GB DDR4 2666MHz SODIMM for laptop upgrades

This single 32GB module brings a large capacity boost to laptops, notebooks and all-in-one systems that accept 260-pin DDR4 SO-DIMMs. It is built as a direct replacement for the Hynix HMAA4GS6CJR8N-VK part number. Buyers who need ECC error correction or registered buffering should look elsewhere, as this module is unbuffered and non-ECC.

Capacity and headroom at 32GB CL19

The 32GB density gives ample headroom for heavy multitasking, large spreadsheets and memory-hungry creative applications on supported platforms. Running at 2666MHz with CL19 latency, it delivers standard DDR4 throughput for everyday workloads. Systems limited to lower maximum module sizes or slower memory controllers will not be able to use the full capacity or speed.

Unbuffered 260-pin layout at 1.2V

The module uses a standard 260-pin SO-DIMM edge connector and operates at the DDR4 nominal voltage of 1.2V, so it fits the same slots as existing DDR4 laptop memory. No heat spreader is fitted, keeping the profile thin for tight chassis clearances. Each unit undergoes quality assurance testing before shipment to ensure reliable operation.

Questions about this item

Will this 260-pin DDR4 2666MHz CL19 module run alongside my existing DDR4 SODIMM?

The module operates at DDR4 2666MHz CL19 with 1.20V voltage and unbuffered design; mixed speeds typically default to the slowest installed module.

How can I confirm the 32GB DDR4 2666MHz CL19 stick is recognised correctly after installation?

Check BIOS or your OS memory information — it should show 32GB capacity, DDR4 type, 2666MHz speed and CL19 latency for the new module.

What comes in the box with this A-Tech 32GB DDR4 2666MHz CL19 SODIMM and what must I buy separately?

The package contains the single 32GB 260-pin DDR4 2666MHz CL19 SODIMM module only; no tools, screws or additional components are included.
