UCS-MR128G2RG3-AX Axiom 128GB PC5-44800 DDR5-5600MHz ECC Registered CL46 Memory Module

UCS-MR128G2RG3-AX Overview

The Axiom UCS-MR128G2RG3-AX is a 128GB DDR5-5600MHz ECC Registered Dual-Rank DIMM (RDIMM) built for Cisco UCS servers and other enterprise-grade systems that require high-speed, high-capacity memory. Delivering a PC5-44800 (5600 MT/s) data rate, this module ensures maximum memory bandwidth — perfect for virtualization clusters, cloud workloads, HPC, AI/ML training, and large-scale database environments.With its dual-rank architecture, this RDIMM provides a balanced approach to capacity and performance, offering lower latency and slightly higher efficiency compared to quad-rank modules, while still delivering extremely high capacity per DIMM. This makes it an excellent choice for systems optimized for fast memory access and scalable throughput.
