4X77A90966-AX Axiom 64GB DDR5-6400MHz 288-Pin DIMM 1.1V Dual Rank Memory Module

4X77A90966-AX Overview

The Axiom 4X77A90966-AX is a high-density 64GB DDR5-6400MHz RDIMM designed for top-tier enterprise servers and workstations that require a massive memory footprint alongside extreme bandwidth. Operating at PC5-51200, this 288-pin Registered DIMM leverages the DDR5 architecture to provide double the efficiency and significantly higher data rates than its DDR4 predecessors. It features a dual-rank configuration and a low 1.1V power profile, which optimizes energy consumption and thermal management in high-density data center environments.
Equipped with integrated Error Correction Code (ECC) technology and a CL46 latency, this module ensures mission-critical data integrity by detecting and repairing single-bit errors in real-time. It is a premier choice for scaling infrastructure to handle the most demanding modern workloads, including large-scale AI modeling, real-time data analytics, and intensive cloud virtualization.
