The HPE 16GB (1x16GB) DDR5-5600 CAS-46 Single Rank x8 Registered Smart Memory Kit (P64342-B21) delivers next-generation DDR5 memory performance engineered specifically for HPE ProLiant Gen11 server platforms. Operating at 5600 MT/s with a CAS latency of 46, this registered DIMM (RDIMM) module leverages the DDR5 architecture's on-die ECC, improved power efficiency through integrated voltage regulation (PMIC), and doubled memory channels compared to DDR4, enabling substantially higher memory bandwidth for demanding server workloads.
As a Single Rank x8 configuration, this kit is optimized to balance capacity, signal integrity, and compatibility across a broad range of HPE Gen11 platforms. HPE Smart Memory technology embeds an on-module Serial Presence Detect (SPD) that enables the server firmware to identify, validate, and unlock platform-specific performance features — including Advanced Memory Protection (AMP) modes such as Advanced ECC — ensuring the module is recognized as a HPE component and operates at its rated DDR5-5600 speed within supported platforms.
This module is purpose-built for enterprise datacenters, AI/ML inference infrastructure, high-performance computing environments, and virtualization hosts where memory bandwidth, density scalability, and validated platform integration are critical. It operates at 1.1V, reducing power consumption relative to equivalent DDR4 implementations, supporting sustainability objectives in modern datacenter deployments. Omnixon Global supplies this module to enterprise and public sector buyers across the UAE, GCC, EMEA, and APAC regions.
