UCS-MR128G4RE1-AX Axiom 128GB PC5-38400 DDR5-4800MHz ECC Registered Memory Module

UCS-MR128G4RE1-AX Overview

The Axiom UCS-MR128G4RE1-AX is a 128GB DDR5-4800MHz ECC Registered DIMM (RDIMM) purpose-built for enterprise-class Cisco UCS servers and other high-performance systems requiring massive memory capacity. Operating at PC5-38400 speeds (4800MT/s), it delivers exceptional throughput for virtualization clusters, AI/ML training, in-memory databases, and mission-critical enterprise workloads.This module features a quad-rank architecture, enabling higher density and efficient bandwidth utilization across multi-channel server configurations. With CL40 CAS latency, it maintains reliable, low-latency access times even in demanding, heavily parallel computing environments.The ECC (Error-Correcting Code) capability ensures superior data integrity by detecting and correcting single-bit memory errors, reducing the risk of data corruption and downtime.
