About the HPE 256GB 4Rx4 PC5-6400AA-R RDIMM Smart Memory Gen12
HPE Registered DIMM with on-die ECC memory module designed for HPE ProLiant Gen12 servers. The HPE 256GB 4Rx4 PC5-6400AA-R RDIMM Smart Memory module delivers enterprise-grade reliability and performance for mission-critical data center workloads. This quad-rank, x4 organization RDIMM (part number P68236-B21) operates at 6400 MT/s with DDR5 technology, providing the speed and capacity needed for demanding server deployments. Running at just 1.1V operating voltage, this module combines advanced error correction with efficient power consumption. The registered DIMM architecture with on-die ECC (ODECC) ensures data integrity across high-capacity memory configurations, while HPE Smart Memory with embedded SPD hub simplifies deployment and configuration in supported platforms.
Data center infrastructure teams—including storage architects, systems engineers, and IT procurement teams—rely on HPE memory modules to maximize uptime and performance in ProLiant Gen12 environments. The 256GB capacity per module enables significant memory consolidation, reducing the number of DIMMs required while maintaining the advanced RAS (Reliability, Availability, Serviceability) features that mission-critical applications demand. Advanced ECC, Lockstep, and Online Spare capabilities (platform-dependent) provide multiple layers of protection against memory errors. The PC5-6400AA-R speed grade meets JEDEC DDR5 standards, ensuring compatibility and consistency across certified HPE infrastructure. Organizations standardizing on HPE memory benefit from validated performance, optimized interoperability, and comprehensive warranty coverage aligned with their server investments.
