About the HPE 128GB 2Rx4 PC5-5600AA-R RDIMM Smart Memory Gen11
A single HPE 128GB 2Rx4 PC5-5600AA-R RDIMM module delivers enough memory capacity to maximize the RAM ceiling in HPE ProLiant Gen11 server configurations, making it the choice for infrastructure teams managing memory-intensive enterprise workloads. This registered dual in-line memory module (RDIMM) operates at 5600 MT/s with DDR5 technology, delivering the speed and bandwidth required for high-performance computing environments where data throughput directly impacts application responsiveness and throughput. Engineered as HPE Smart Memory with onboard SPD firmware, the P64336-B21 integrates directly with iLO health telemetry, providing platform-authenticated memory subsystem support and real-time diagnostic visibility across your infrastructure.
The module features error correcting code (ECC) with single-bit error correction and multi-bit error detection, critical safeguards for mission-critical systems that cannot tolerate silent data corruption. Operating at 1.1 V within the 0°C to 85°C range, this 288-pin DIMM with dual rank configuration (2Rx4) and 64-bit data bus architecture is built to sustain demanding enterprise operations. For IT procurement teams standardizing on HPE infrastructure, this memory module ensures consistency, compatibility, and the reliability telemetry integration that HPE ProLiant Gen11 servers demand.
