A-Tech 4GB DDR4 2133MHz CL15 260-Pin SODIMM Laptop RAM

A-Tech 4GB DDR4 2133MHz SODIMM

This 4GB DDR4 module upgrades laptops, notebooks, and all-in-one systems that accept 260-pin SO-DIMM memory. It replaces Crucial CT4G4SFS8213 and CT2K4G4SFS8213 parts directly. The unbuffered, non-ECC design suits mainstream consumer platforms. Buyers needing ECC or registered memory for workstation or server boards cannot use this module.

Capacity and headroom for everyday loads

The single 4GB stick runs at 2133MHz with CL15 latency and 1.20V voltage. It handles web browsing, office applications, and light multitasking comfortably. Systems requiring more than 4GB total memory or higher frequencies for demanding workloads will exceed this module's capacity and speed limits.

Thermals noise and power draw in normal use

Standard 1.2V DDR4 operation keeps power consumption low and heat output minimal inside compact laptop chassis. The module uses major brand chips tested for reliability without active cooling. Silent passive operation is typical for this form factor and voltage level.
