About the HPE 64GB 2Rx4 PC5-6400AA-R RDIMM Smart Memory Gen12
Operating at CL40 latency with 1.1 V supply voltage, the HPE 64GB 2Rx4 PC5-6400AA-R RDIMM Smart Memory Gen12 delivers the low-latency, low-power characteristics critical for high-frequency trading platforms and in-memory database environments. This enterprise-class module combines HPE's registered DIMM architecture with native DDR5 on-die error correction, ensuring both performance and reliability in mission-critical infrastructure.
Built on HPE's Smart Memory technology, the P68233-B21 is purpose-engineered for HPE ProLiant Gen12 Servers where data integrity and thermal efficiency matter most. IT procurement teams and storage architects standardizing on HPE infrastructure will appreciate the ECC protection, 6400 MT/s throughput, and 288-pin DDR5 form factor that scales across modern server deployments. The module's 2Rx4 dual-rank configuration with 64-bit data bus balances capacity density against latency—ideal for virtualization, analytics, and transactional workloads. Full RoHS compliance and an operating temperature range of 0°C to 85°C round out this solution for demanding data center environments.
