Laptop DDR4 SODIMM upgrade

This 8 GB DDR4 module fits 260-pin SO-DIMM slots in laptops, notebooks and all-in-one PCs. It runs at 2133 MHz with CL15 latency and standard 1.2 V power. Major-brand chips are tested for dependable operation in both AMD and Intel platforms.

Replaces Kingston KCP421SS8/8 equivalents

The module is a direct drop-in for Kingston part numbers KCP421SS8/8, KVR21S15S8/8 and the dual-channel kit KVR21S15S8K2/16. The upgrade is worthwhile when the system currently has 4 GB or a single slower stick and the motherboard supports DDR4 2133 speeds.

8 GB single-rank capacity

One 1Rx8 module provides enough headroom for everyday multitasking, web browsing and office applications. Memory-intensive workloads such as large video projects, virtual machines or heavy creative suites will exceed the available space and require additional modules or higher-density kits.
