HPE 32GB 1Rx4 PC5-4800AA-R RDIMM Smart Memory Gen11

The HPE 32GB 1Rx4 PC5-4800AA-R RDIMM Smart Memory Gen11 (P50309-B21) is a single-rank, registered DDR5 module engineered specifically for HPE ProLiant Gen11 servers. Operating at a native DDR5 speed of 4800 MT/s with a 288-pin RDIMM form factor, this module delivers substantially higher bandwidth and improved power efficiency compared to previous-generation DDR4 solutions. The registered (buffered) design incorporates an on-DIMM register that re-drives command and address signals, enabling robust signal integrity across high-density server configurations without compromising throughput.

As part of HPE's Smart Memory portfolio, this module integrates an HPE-specific Serial Presence Detect (SPD) and firmware layer that enables direct communication with HPE ProLiant's Integrated Lights-Out (iLO) management subsystem and Advanced Memory Protection features. This tight platform integration supports real-time health monitoring, proactive fault detection, and compatibility validation within HPE's server ecosystem. The ECC (Error Correcting Code) functionality built into DDR5 RDIMM architecture provides both in-DRAM ECC and traditional DIMM-level ECC correction, offering a dual layer of data integrity protection critical for enterprise-grade reliability.

The P50309-B21 is optimized for memory-bandwidth-intensive and latency-sensitive enterprise workloads, including in-memory databases, virtualized infrastructure, and AI/ML inference tasks that demand high-capacity, high-speed DRAM. Its 1Rx4 single-rank organization balances per-DIMM capacity with the ability to populate a large number of modules per server without degrading memory bus speed, making it well suited for scale-out datacenter deployments across UAE, GCC, EMEA, and APAC regions.

Ideal for

• High-density VMware vSphere or Microsoft Hyper-V virtualization hosts requiring large per-socket memory capacity with consistent ECC-protected uptime
• In-memory database workloads such as SAP HANA, Oracle In-Memory, or Redis Enterprise where sustained DDR5 bandwidth directly accelerates query throughput
• AI and machine learning inference servers that leverage large DRAM buffers to stage model weights and intermediate tensors between GPU compute cycles
• Enterprise HPC clusters and technical computing nodes where memory bandwidth is the primary performance bottleneck for simulation and modeling tasks
• Cloud-native microservices platforms and containerized Kubernetes environments running on HPE ProLiant Gen11 infrastructure requiring validated, iLO-managed memory
• Financial services real-time analytics and risk-calculation platforms that depend on sub-millisecond in-memory data access with hardware-level error correction
