Hewlett Packard Enterprise 726724-B21 Memory Module

The Hewlett Packard Enterprise 726724-B21 Memory Module is a 64GB DDR4 SDRAM Load-Reduced (LRDIMM) 288-pin ECC memory module designed for HPE ProLiant Gen9 servers. It uses a Quad Rank x4 organization, operates at 1.2V, and runs DDR4-2133P (PC4-17000) speeds to boost multitasking and data processing in demanding environments. This module—manufactured by HPE with part number 726724-B21, spare 774176-001, and assembly 752373-091—is intended for server memory upgrades, failed DIMM replacements, and capacity expansion to restore reliable operation in rack and blade servers, virtualization hosts, enterprise storage systems, and other business-critical applications. It supports stable performance in enterprise data centers, virtualization clusters, database servers, cloud infrastructure, and storage platforms that require high-capacity ECC memory. Compatible specifically with HPE ProLiant Gen9 server platforms, the module helps improve workload performance by increasing available memory while maintaining error-checked reliability essential for mission-critical workloads.
