HPE 1TB (8x128GB) DDR5-5600 CAS-46 Registered Smart Memory Kit

The HPE 1TB (8x128GB) DDR5-5600 CAS-46 Registered Smart Memory Kit (P67581-B21) delivers one terabyte of high-bandwidth system memory through eight 128GB Registered DIMMs operating at DDR5-5600 MT/s. Built on the DDR5 architecture, these modules leverage on-die ECC, improved power management through PMIC integration, and a 64-bit channel design with burst length of 16, enabling substantially higher throughput and improved signal integrity compared to prior generations. The Registered (RDIMM) buffer design isolates the memory controller from the DRAM load, allowing large-capacity configurations essential for memory-intensive enterprise platforms.

As HPE Smart Memory, these DIMMs are engineered with embedded SPD (Serial Presence Detect) firmware that enables HPE ProLiant and Synergy servers to authenticate, identify, and optimize the memory subsystem automatically. This intelligence layer supports advanced RAS (Reliability, Availability, and Serviceability) features including Post Package Repair (PPR), improved thermal monitoring, and platform-level memory health reporting through HPE iLO. The CAS latency of 46 at 5600 MT/s balances peak bandwidth with the access-latency profiles demanded by enterprise application tiers.

This kit targets workloads that require both extreme memory capacity and sustained high-bandwidth throughput within a single server. Large-scale in-memory databases, AI and machine learning model training, high-performance computing simulations, and real-time analytics platforms all benefit directly from the 1TB aggregate capacity and DDR5-5600 speed. Deployment is suited to HPE ProLiant Gen11 servers and HPE Synergy compute modules that explicitly support DDR5 RDIMM configurations at this capacity point.

Ideal for

• In-memory database platforms such as SAP HANA requiring multi-hundred-gigabyte to terabyte-scale active datasets resident entirely in RAM for sub-millisecond query response
• AI and deep learning model training workloads where large parameter sets and high-bandwidth data ingestion from NVMe storage benefit from DDR5-5600 memory bandwidth across eight populated DIMM slots
• High-performance computing (HPC) simulation environments in life sciences, computational fluid dynamics, and financial risk modeling that demand both high capacity and low-latency memory access
• Virtualization hosts running dense virtual machine estates where aggregate guest RAM requirements approach or exceed one terabyte on a dual-socket ProLiant Gen11 platform
• Real-time analytics and data warehousing appliances that hold large working sets in-memory to accelerate BI query engines and columnar data processing frameworks
• Enterprise Kubernetes and container orchestration nodes requiring large memory pools to support high pod density with memory-guaranteed QoS classes on AI inference serving infrastructure
