M321R8GA0EB0-CWM Samsung 64GB DDR5-5600MHz Memory Module

M321R8GA0EB0-CWM Overview

The Samsung M321R8GA0EB0‑CWM 64 GB DDR5‑5600 MHz RDIMM is a high‑capacity, enterprise‑grade memory module built for server and professional systems that need both performance and reliability. It’s based on DDR5 SDRAM technology with an effective 5600 MT/s data rate (PC5‑44800) and uses ECC (Error‑Correcting Code) to help detect and correct memory errors — a key requirement in mission‑critical and 24×7 server environments.
This module features a 288‑pin Registered DIMM (RDIMM) form factor that improves signal stability and allows systems to handle larger total memory capacities and more DIMMs per system compared with unbuffered memory. Its dual‑rank x4 configuration helps optimize data access efficiency across memory channels for multi‑threaded and data‑intensive workloads.
