HMCT04MHBRC Hynix Memory 128GB DDR5 6400MHz RDIMM Low Profile Memory Module


HMCT04MHBRC Overview

The Hynix HMCT04MHBRC 128 GB DDR5-6400 MHz RDIMM is a enterprise-class server memory module engineered for high-performance computing, data center servers, and professional systems where large memory capacity, speed, and reliability are essential. This module conforms to the DDR5-6400 (PC5-51200R) standard, providing a high data transfer rate of 6400 MT/s, which helps improve overall system throughput for demanding workloads such as virtualization, in-memory databases, analytics, and multi-threaded applications.
As a Registered DIMM (RDIMM) with ECC (Error-Correcting Code) support, this module includes built-in error detection and correction to help maintain data integrity and uptime. The “registered” feature buffers communication between the memory controller and DRAM chips, improving signal reliability and stability — especially when multiple memory modules are installed in server platforms.
