A-Tech 4GB DDR4 2133MHz CL15 1.2V Desktop RAM

4GB DDR4 2133MHz Desktop Module

This A-Tech module provides 4GB of DDR4 memory at 2133MHz with CL15 latency and 1.2V operation. It uses a standard 288-pin DIMM form factor and unbuffered, non-ECC architecture. The single stick is built with major-brand chips and tested for broad AMD and Intel desktop compatibility. It serves as a direct replacement for Crucial part CT4G4DFS8213.

Ideal for Basic DDR4 Desktop Upgrades

This kit suits owners of DDR4 desktops needing a modest capacity boost for everyday tasks and light multitasking. Systems limited to 2133MHz speeds will run this module at its rated frequency without configuration. Builders requiring ECC error correction, registered buffering, higher capacities, or faster speeds should select different modules that match those specifications.

2133MHz Speed Rating Determines Fit

The module operates at a tested frequency of 2133MHz (PC4-17000) with CL15 timings at 1.2V. This speed rating is the primary specification that dictates compatibility with your motherboard and CPU memory controller. Verify your platform supports DDR4-2133 before purchase to ensure correct operation and stability.
