P73447-B21 HPE 256GB PC5-51200 DDR5-6400MHz ECC Registered CL52 288-Pin Memory Module

P73447-B21 Overview

The HPE P73447-B21 is a 256GB DDR5 Registered DIMM (RDIMM) engineered for enterprise servers and high-performance computing platforms requiring maximum memory capacity and speed. Operating at 6400MHz (PC5-51200) with CL52 latency and a quad-rank (4R) architecture, it delivers very high memory bandwidth for demanding workloads such as virtualization, large-scale databases, AI/ML, and analytics.Equipped with ECC (Error-Correcting Code), this module detects and corrects memory errors automatically, ensuring data integrity and system stability in mission-critical environments. Its 288-pin RDIMM form factor and 1.1V low-voltage operation offer energy-efficient performance while supporting multi-channel memory configurations for optimal throughput and scalability.
