A9781931-AX Overview

The Axiom A9781931-AX is a high-density 128GB DDR4-2666MHz Load Reduced ECC memory module designed for enterprise servers and large-scale memory-intensive applications. Operating at 2666MHz with CL19 timings, octal-rank architecture, and registered buffering, this 288-pin LRDIMM runs efficiently at 1.2V while delivering massive capacity in a single module. It is an ideal solution for data centers, virtualization hosts, in-memory databases, and high-performance computing environments that demand both extreme capacity and rock-solid reliability. By using load-reduced technology, this LRDIMM significantly reduces the electrical load on the memory bus, allowing servers to support much higher memory densities and more modules per channel without sacrificing stability or speed.
