HPE 48GB (1x48GB) Dual Rank x8 DDR5-4800 CAS-40-39-39 Registered Smart Memory Kit

The HPE 48GB (1x48GB) Dual Rank x8 DDR5-4800 CAS-40-39-39 Registered Smart Memory Kit (P50315-B21) delivers high-density, high-bandwidth memory capacity engineered specifically for HPE ProLiant Gen11 servers. Built on the DDR5 architecture, this module operates at 4800 MT/s with a CAS latency profile of 40-39-39, offering a significant generational leap in bandwidth and power efficiency over DDR4 predecessors. The x8 dual-rank configuration maximizes memory capacity per DIMM slot while maintaining the signal integrity and reliability demanded by enterprise and datacenter environments.

As an HPE Smart Memory module, this kit incorporates an HPE-specific Serial Presence Detect (SPD) that enables the server to recognize and validate the memory, unlocking advanced platform features including enhanced RAS (Reliability, Availability, and Serviceability) capabilities and optimized memory subsystem performance. The Registered (RDIMM) design uses a register component between the memory controller and the DRAM chips, reducing electrical loading on the memory bus and enabling stable operation in multi-DIMM configurations across high-core-count processor platforms.

The 48GB capacity point addresses enterprise workloads that require large, contiguous memory footprints without exhausting all available DIMM slots, leaving headroom for future memory expansion. Operating on the DDR5 standard's native on-die ECC alongside the server platform's full ECC implementation, this module is well-suited for AI inferencing, in-memory databases, virtualization hosts, and real-time analytics platforms where data integrity and sustained throughput are non-negotiable requirements.

Ideal for

• High-density VMware vSphere or Microsoft Hyper-V virtualization hosts requiring large per-VM memory allocations across HPE ProLiant Gen11 two-socket servers
• In-memory database deployments such as SAP HANA, Redis, or Oracle TimesTen where working dataset size directly impacts query latency and throughput
• AI and machine learning inferencing nodes that require substantial DRAM capacity to stage model weights and intermediate tensors without frequent I/O offloading
• Real-time analytics and streaming data platforms (Apache Kafka, Apache Flink) benefiting from DDR5-4800 bandwidth to sustain high-velocity data ingestion pipelines
• Enterprise resource planning (ERP) application servers running SAP S/4HANA or Oracle E-Business Suite where consolidated workloads demand reliable high-capacity memory
• Cloud-native Kubernetes worker nodes hosting stateful microservices and caching layers that require predictable memory performance under variable workload concurrency
