HPE 8GB (1x8GB) Single Rank x8 DDR5-4800 CAS-40-39-39 Unbuffered Smart Memory Kit

The HPE 8GB (1x8GB) Single Rank x8 DDR5-4800 CAS-40-39-39 Unbuffered Smart Memory Kit (P43327-B21) is a next-generation DDR5 memory module engineered to meet the performance and reliability demands of modern enterprise server environments. Operating at a native frequency of 4800 MT/s with a CAS latency profile of 40-39-39, this unbuffered DIMM delivers substantial bandwidth improvements over prior DDR4 generations, enabling faster data throughput for compute-intensive server workloads. The module is manufactured and validated by HPE to exacting standards, ensuring full compatibility with HPE ProLiant Gen11 servers that support DDR5 unbuffered memory.

As an HPE Smart Memory module, this kit incorporates an HPE Serial Presence Detect (SPD) ROM that is recognized by HPE ProLiant server management firmware, enabling the system to confirm the installation of HPE memory. This Smart Memory designation also allows HPE iLO and UEFI BIOS to unlock certain memory configuration capabilities and provide enhanced diagnostics that may not be available with third-party alternatives. The single-rank, x8 organization balances density and signal integrity, making it well-suited for single-socket and dual-socket deployments where slot count flexibility and stable operation across temperature ranges are critical considerations.

Designed for datacenter, edge, and AI inference infrastructure, the P43327-B21 operates on DDR5's reduced 1.1V supply voltage, contributing to improved power efficiency per gigabyte compared to DDR4 equivalents operating at 1.2V. This efficiency characteristic is particularly relevant in high-density server deployments where thermal envelope and power consumption directly impact total infrastructure operating expenditure. The module conforms to JEDEC DDR5 standards and is validated within HPE's rigorous qualification process, supporting enterprise IT teams in building dependable, standards-aligned server memory configurations across UAE, GCC, EMEA, and APAC datacenter environments.

Ideal for

• Entry-level HPE ProLiant Gen11 server deployments requiring DDR5 performance at 1-DIMM-per-channel configurations for general-purpose enterprise compute workloads
• Edge server and remote-office infrastructure builds where compact 8GB DDR5 unbuffered modules provide cost-efficient baseline memory with native HPE firmware compatibility
• AI inference nodes and lightweight analytics platforms leveraging DDR5-4800 bandwidth to accelerate data movement between CPU and memory subsystem
• Virtualization host memory baseline configuration on HPE ProLiant platforms where HPE Smart Memory validation ensures hypervisor stability and iLO-level diagnostics
• High-availability enterprise application servers where HPE firmware-level memory recognition and health monitoring reduce unplanned downtime risk
• Incremental memory expansion in existing HPE Gen11 server fleets, adding capacity in single-module increments while maintaining a homogeneous, HPE-validated memory environment
