HMCG78MEBRA113N | Hynix 16GB 4800MHz DDR5 PC5-38400 ECC Registered CL40 288-Pin DIMM 1.1V Single Rank x8 Memory Module

The SK Hynix HMCG78MEBRA113N is a 16GB DDR5 ECC Registered DIMM (RDIMM) designed for enterprise servers and data center environments. It is commonly used in systems such as HPE ProLiant Gen10+/Gen11, Dell PowerEdge 16G series, Lenovo ThinkSystem, and other server platforms based on Intel Xeon Scalable (4th/5th Gen) and AMD EPYC processors.

This module is part of SK Hynix’s DDR5 server memory lineup, built to deliver high bandwidth, improved power efficiency, and scalable memory performance for modern workloads such as virtualization, cloud computing, AI/ML processing, HPC (high-performance computing), and large database systems.

It operates at DDR5-4800 MT/s (PC5-38400R) and uses ECC (Error-Correcting Code) to automatically detect and correct memory errors, ensuring data integrity and system stability in mission-critical environments.
