815100-B21-AO AddOn 32GB DDR4-2666MHz DIMM Memory Module
815100-B21-AO Overview
The AddOn 815100-B21-AO is an enterprise-class 32GB DDR4 Registered ECC memory module engineered for high-availability enterprise servers, corporate workstations, and multi-socket data center nodes. Operating at a native frequency of 2666MHz (PC4-21300), this module provides a high-density, reliable data foundation optimized to handle virtualized workloads, dense database backends, and mainstream multi-threaded compute operations.
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.
