P19045-B21-AM Addon HPE 64GB PC4-23400 DDR4 Memory Module

P19045-B21-AM Overview

The AddOn P19045-B21-AM is an enterprise-class 64GB DDR4 Registered ECC memory module specifically engineered for high-availability enterprise servers, data centers, and high-performance multi-socket workstations. Operating at a native speed of 2933MHz (PC4-23400), this module provides an ultra-high-density data foundation optimized to support demanding multi-threaded compute workloads, dense virtualization layers, and massive database applications.
A defining characteristic of this module is its Registered ECC (RDIMM) architecture packaged into an industry-standard 288-pin server form factor. It features an onboard hardware register that buffers command and address signals, effectively isolating the electrical load from the host processor’s memory controller. This configuration is structurally necessary for stabilizing high-density memory pools.
