About the HPE P19047-B21 - HPE DDR4 128GB 4RX4 2933Y
HPE DDR4 Quad Rank x4 LRDIMM memory for enterprise ProLiant platforms. The P19047-B21 is a 128GB Load-Reduced DIMM (LRDIMM) module engineered for HPE ProLiant Gen10 and Gen10 Plus servers. As a 4RX4 (quad rank x4) configuration with full ECC error correction, this module delivers the capacity and reliability required by data centres handling mission-critical workloads. Operating at 2933 MT/s with PC4-2933Y-L speed rating and a 1.2V supply, the module slots into standard 288-pin DIMM architecture and carries HPE Smart Memory certification, ensuring validated performance and compatibility across supported platforms. The module is RoHS compliant, meeting modern environmental standards.
Enterprise IT infrastructure teams—including storage architects, system administrators, and procurement departments—select this HPE Smart Memory solution when scaling memory capacity in multi-socket, high-availability environments. The 4RX4 rank configuration optimises signal integrity across densely populated memory channels, while the LRDIMM form factor reduces electrical load on memory controllers, enabling higher module counts per server without degradation. ECC protection safeguards data integrity during compute-intensive operations, making this module ideal for virtualisation clusters, database servers, and mixed workload deployments where downtime carries substantial cost. Organisations standardising on HPE infrastructure benefit from certified memory modules that ship pre-validated for their target platforms, eliminating integration risk.
