About the HPE 128GB 2Rx4 PC5-6400AA-R RDIMM Smart Memory Gen12
DDR5 PC5-6400AA-R memory operating at 6400 MT/s delivers 128GB capacity per module for next-generation HPE ProLiant infrastructure. The HPE 128GB 2Rx4 PC5-6400AA-R RDIMM Smart Memory Gen12 (part number P68234-B21) combines high-speed data transfer with enterprise-grade error correction to support demanding workloads in mission-critical environments. Built as a registered DIMM with dual-rank, x4 organization, this memory module integrates Advanced ECC with ADDDC support via HPE AMP to protect against bit errors and data corruption.
Storage architects and IT procurement teams selecting HPE infrastructure will find this module purpose-built for ProLiant Gen12 servers. Operating at 1.1V with an operating temperature range of 0°C to 85°C, the P68234-B21 features the 288-pin RDIMM form factor and HPE Smart Memory SPD with platform validation to ensure seamless compatibility and automated configuration. The combination of 6400 MT/s throughput and on-die ECC plus chipkset-level ECC delivers the reliability and performance required for consolidated virtualization, database clusters, and analytics platforms. Platform-dependent RAS features including Online Spare Memory provide additional data protection capabilities.
Enterprise Deployment Scenarios
