HPE 64GB 2Rx4 PC5-4800AA-R RDIMM Smart Memory Gen11

The HPE 64GB 2Rx4 PC5-4800AA-R RDIMM Smart Memory Gen11 (P50310-B21) is a DDR5-4800 registered dual-rank module engineered specifically for HPE ProLiant Gen11 servers. Built on the DDR5 architecture, it operates at a native speed of 4800 MT/s with an ECC-protected data path, delivering substantial memory bandwidth improvements over DDR4 predecessors. The dual-rank, x4 organization provides enhanced memory capacity density while the registered (buffered) DIMM topology ensures signal integrity across multi-slot configurations in enterprise server platforms.

As an HPE Smart Memory component, this module contains an HPE-embedded Serial Presence Detect (SPD) that enables the server's Intelligent Memory controller to verify module authenticity and unlock optimized performance profiles. This integration allows HPE ProLiant Gen11 systems to apply factory-validated timing parameters, reducing configuration errors and supporting advanced RAS (Reliability, Availability, and Serviceability) features including Post Package Repair (PPR) and on-die ECC. The 1.1V operating voltage of DDR5 contributes to improved power efficiency relative to DDR4's 1.2V standard, a meaningful consideration at scale in high-density rack deployments.

This module is purpose-suited for memory-intensive enterprise workloads where capacity, bandwidth, and data integrity converge as critical requirements. AI inference and training pipelines, in-memory databases, virtualized infrastructure, and high-performance computing environments all benefit from the increased throughput and expanded addressable memory ceiling that DDR5-4800 provides. The RDIMM format and Gen11 platform optimization make P50310-B21 a foundational building block for datacenter operators in UAE, GCC, EMEA, and APAC regions scaling infrastructure for modern compute demands.

Ideal for

• In-memory database acceleration for platforms such as SAP HANA and Oracle Database In-Memory, where large working sets must reside entirely in DRAM for sub-millisecond query response
• AI and machine learning model training and inference on HPE ProLiant Gen11 servers, leveraging DDR5-4800 bandwidth to sustain data throughput between CPU and accelerators
• Enterprise virtualization hosts running VMware vSphere or Microsoft Hyper-V with high VM density, where expanded memory capacity reduces swap activity and improves consolidation ratios
• High-performance computing (HPC) clusters requiring maximum memory bandwidth for simulation, computational fluid dynamics, and genomics workloads
• Cloud-native application servers and Kubernetes worker nodes demanding large memory footprints per node to support containerized microservices at scale
• Business-critical ERP and analytics environments requiring continuous uptime, where on-die ECC and advanced RAS features minimize uncorrectable error risk
