HPE 879505-B21 8GB DDR4 SDRAM Memory Module

HPE 879505‑B21 – 8 GB DDR4‑2666 ECC Unbuffered DIMM

Overview

The HPE 879505‑B21 is an 8 GB DDR4‑2666 MHz ECC unbuffered memory module built for entry to mid‑tier server loads in the HPE ProLiant Gen10 family. It offers a single‑rank x8 configuration useful for basic virtualization, web hosting or general‑purpose compute where capacity rather than maximum throughput is the priority. It fits standard 288‑pin DIMM slots, runs at 1.2 V and supports ECC error correction, helping maintain stability under moderate workloads. Ideal for small‑to‑medium business servers, remote/branch office use or as a baseline expansion module in a larger memory array.

Key Features

• 8 GB capacity in a single module allows cost‑effective memory incremental upgrades and straightforward server handling.

• DDR4‑2666 (PC4‑21300) speed ensures compatibility with Gen10 platforms’ supported memory rails and hybrid workloads.

• ECC (Error‑Correcting Code) and unbuffered design—balances reliability with cost for standard server use rather than demanding mission‑critical caching.

• Single‑rank x8 configuration reduces electrical load on the memory channel and maximises compatibility when mixing modules.
