Capacity and form factor

This A-Tech module provides 4GB of DDR4 laptop memory in a 260-pin SO-DIMM form factor. It operates at 3200MHz with a CAS latency of CL22 and runs at the standard 1.20V voltage. The unbuffered, non-ECC design targets mainstream notebook and all-in-one systems.

Compatibility fit

The stick is validated as a direct replacement for Hynix HMA851S6CJR6N-XN and HMA851S6DJR6N-XN part numbers. It suits owners of those specific modules or systems requiring identical DDR4 3200 specifications. Buyers whose laptops demand ECC, registered memory, a different pin count, or a higher density per slot should look elsewhere.

Testing and support impact

Every unit undergoes quality assurance testing before shipping to verify reliable operation. The purchase includes a lifetime warranty from A-Tech and access to their United States-based technical support team for installation or troubleshooting assistance.

Questions sur cet article

What laptop slot does the 260‑pin DDR4 SODIMM fit?

It installs in any standard 260‑pin DDR4 SO‑DIMM socket found in current laptops and all‑in‑one systems.

Will the CL22 3200 MHz module run with older DDR4 memory already in my machine?

Yes, it is unbuffered non‑ECC DDR4 and will operate at the highest common speed supported by the platform alongside existing sticks.

How can I confirm the stick is running at 3200 MHz after installation?

Open Task Manager or a hardware monitor and check that the reported memory speed shows 3200 MHz with CL22 timings.
