A-Tech 8GB DDR4 2666 Module

This A-Tech desktop memory module provides 8GB of DDR4 capacity at 2666MHz with CL19 latency. It uses a standard 288-pin DIMM form factor and operates at 1.2V. The unbuffered, non-ECC design suits mainstream AMD and Intel desktop platforms.

Dell-Compatible Upgrade for Standard Desktops

The module replaces Dell part numbers including 370-ADZL, AA101752, AA103685 and AA286623. It suits owners of those systems seeking a direct drop-in upgrade. Builders needing ECC, registered buffering, or speeds above 2666MHz should look at other modules.

8GB Capacity for Everyday Multitasking

The single 8GB stick handles web browsing, office suites and light creative workloads comfortably. Heavy multitasking, virtual machines or large media projects will exceed this capacity and require additional modules or higher-density kits.
