About the Samsung DDR5 32GB RDIMM 6400MHz

Samsung DDR5 32GB Dual Rank RDIMM with native on-die ECC delivers mission-critical memory reliability for Intel Xeon Scalable (Sapphire Rapids and later) and AMD EPYC (Genoa and later) server platforms. Built as a registered DIMM with 2Rx4 configuration, the Samsung M321R4GA0BB6-CQKMQ combines 32GB capacity, 6400 MT/s data transfer rate, and integrated error correction—essential for data centers where memory integrity cannot be compromised. This module operates at 1.1V with CAS Latency 46 and maintains stability across 0°C to 85°C operating temperatures, making it suitable for dense, high-performance compute environments.

Enterprise storage architects and IT procurement teams will appreciate the native DDR5 ECC architecture, which includes on-module PMIC for power management and Decision Feedback Equalization (DFE) signal integrity features per JEDEC DDR5 specification. The 288-pin configuration and 64-bit data bus width ensure compatibility with next-generation Xeon and EPYC infrastructures. Samsung's manufacturing rigor on part number M321R4GA0BB6-CQKMQ guarantees consistent performance across high-volume deployments. Contact Omnixon Global for technical specifications, availability, and RFQ details.
