ADATA SO-DIMM 4GB (1 x 4GB) DDR4 2666 MHz, CL19 Memory

The ADATA AD4S26664G19-SGN is a 4 GB DDR4 memory module engineered for installation in compatible laptops and compact computing systems. Operating at a frequency of 2666 MHz with a CAS latency of 19, this module provides a standard performance uplift for general computing and multitasking applications. It is designed as a single-module upgrade or replacement, adhering to JEDEC industry standards to ensure broad system compatibility. The module functions at a low voltage of 1.2 V, which contributes to the overall power efficiency of portable devices.

This memory module is built on the 260-pin SO-DIMM form factor, the standard interface for modern notebooks and certain small form-factor PCs that utilize DDR4 memory. As an unbuffered and non-ECC module, it is specified for consumer-grade systems where these advanced features are not typically required. Its physical dimensions are compact, ensuring it fits correctly within the constrained space of laptop memory slots. The design does not incorporate a heat spreader, which is common for memory modules with these operational specifications and power consumption levels.
