AA138422-AX Axiom AX DDR4 16GB DIMM 288-pin

AA138422-AX Overview

The Axiom AA138422-AX is a high-performance 16GB DDR4 memory module specifically engineered to serve as a 100% compatible equivalent for Dell PowerEdge servers and Precision workstations. Operating at 2666MHz (PC4-21300), it provides a stable and efficient data foundation for intensive enterprise workloads, database management, and multi-tenant virtualization.
A defining characteristic of this module is its Registered ECC (RDIMM) architecture. By utilizing an onboard register to buffer command and address signals, it significantly lowers the electrical load on the system’s memory controller. This is a structural and mechanical necessity for enterprise hardware platforms, ensuring superior signal integrity and rock-solid system stability even when multiple memory slots are fully populated across the motherboard.
