SK hynix HMA851S6DJR6N-XN 8GB (2x4GB) DDR4 3200 CL22 laptop RAM

8 GB DDR4 3200 SO-DIMM kit

This kit provides two 4 GB modules for a total of 8 GB of DDR4 laptop memory. Each stick is a 260-pin SO-DIMM rated at 3200 MT/s with a CAS latency of CL22 and operates at the standard 1.20 V. The modules are unbuffered and non-ECC, matching the typical requirements for consumer notebooks.

Suits standard notebook upgrades.

The kit is intended for ordinary laptops that accept unbuffered, non-ECC DDR4 SO-DIMMs. It will not work in systems that require ECC memory or registered modules, nor in machines limited to earlier DDR generations. Buyers needing more than 8 GB total capacity or lower latency figures should consider other configurations.

CL22 latency at DDR4 3200

The decisive specification is the CL22 timing at the rated 3200 MT/s speed. This latency value determines how the memory performs in latency-sensitive workloads and whether it meets the timing requirements of a particular platform. Verify that the target laptop can run DDR4 at this speed and latency before purchase.
