About the HPE 256GB (1x256GB) Octal Rank x4 DDR5-4800 CAS-40-39-39 Load Reduced Smart Memory Kit

The HPE 256GB (1x256GB) Octal Rank x4 DDR5-4800 CAS-40-39-39 Load Reduced Smart Memory Kit (P50314-B21) represents a high-density DDR5 memory solution engineered for HPE ProLiant Gen11 servers operating under the most demanding enterprise and AI workloads. Built on the DDR5-4800 standard with a CAS latency profile of 40-39-39, this Load Reduced DIMM (LRDIMM) architecture employs an on-module data buffer to reduce the electrical load presented to the memory controller, enabling higher-capacity memory populations per channel without sacrificing signal integrity or stability at full-rack scale deployments.

As an octal-rank (8Rx4) x4 device, the module achieves its 256GB capacity through eight independent rank groups, each organized across a x4-wide DRAM bus per chip, optimizing bit density per physical DIMM slot. HPE Smart Memory technology integrates an on-module Serial Presence Detect (SPD) with HPE-specific configuration data that enables automatic recognition and validation by HPE ProLiant system firmware (UEFI/BIOS), streamlining memory population verification and reducing configuration errors in large-scale server deployments. The module operates at 1.1V, consistent with the DDR5 standard, contributing to improved energy efficiency relative to prior DDR4 generations at equivalent or greater capacity points.

This memory kit is purpose-built for enterprise datacenters, high-performance computing (HPC) clusters, in-memory database platforms, and AI/ML inference and training infrastructure where maximum per-socket memory addressability is a primary architectural constraint. Its compatibility with HPE's memory validation and firmware ecosystem ensures seamless integration into HPE ProLiant Gen11 platforms, supporting the highest memory capacity configurations available within those server generations.

Ideal for

  • In-memory database platforms (SAP HANA, Oracle In-Memory, Redis Enterprise) requiring multi-terabyte addressable memory per server node
  • AI and machine learning training and inference workloads where large model parameter sets and dataset batches must reside entirely in DRAM to minimize latency
  • High-performance computing (HPC) simulations in computational fluid dynamics, genomics, and financial risk modeling that demand maximum per-socket memory bandwidth and capacity
  • Virtualization hosts running high VM-density workloads on HPE ProLiant Gen11 platforms, where per-VM memory allocation requires maximum physical DRAM population
  • Enterprise ERP and analytics platforms processing large in-memory datasets with strict latency SLAs that preclude NVMe or storage-tier data access during peak operations
  • Datacenter consolidation initiatives replacing multiple lower-capacity servers with fewer high-memory-density nodes to reduce rack footprint, power draw, and interconnect complexity
