About the HPE P19043-B21 - HPE DDR4 32GB 2RX4 2933Y
At 32 GB per module, this HPE memory module enables enterprise data center deployments to reach maximum system capacity on HPE ProLiant Gen10 and Gen10 Plus servers. The HPE P19043-B21 is a registered DDR4 RDIMM engineered for mission-critical environments where data integrity and reliability cannot be compromised. Built to HPE SmartMemory specifications, this module delivers the performance and protection standards that storage architects, infrastructure teams, and IT procurement departments expect from enterprise-class hardware.
The P19043-B21 combines high-speed memory performance with advanced error correction and platform-level health monitoring. Operating at 2933 MT/s with CAS Latency 21, this dual-rank module supports demanding workloads across virtualization, database, and analytics platforms. HPE's registered DIMM architecture and ECC capability provide Single Device Data Correction (SDDC) protection, while integration with HPE iLO enables real-time module identity and health reporting. The 1.2 V operating voltage and 288-pin DIMM form factor ensure compatibility across targeted server generations, and the module's 0°C to 85°C operating temperature range supports both standard and high-density data center environments. Memory protection features—including Advanced ECC, Online Spare Memory, and Mirrored Memory capabilities—are platform-dependent but available for enterprise deployments requiring maximum uptime and data protection.
