About the SK Hynix DDR5 RDIMM 128GB 6400MT/s Server Module
The SK Hynix DDR5 RDIMM 128GB is a registered ECC memory module rated at 6400 MT/s, built for next-generation dual-socket servers that demand large memory footprints and high bandwidth. Based on advanced DDR5 die with on-module ECC and improved power management, it supports memory-bound workloads such as in-memory databases, virtualization consolidation, and analytics.
The module uses on-DIMM power management ICs and a registering clock driver to maintain signal integrity at high data rates across fully populated channels. With server-grade reliability features including error correction and post-package repair, it is suited to continuous-duty enterprise and HPC platforms.
Ideal for
- In-memory databases and caching layers
- High-density virtualization and consolidation
- HPC and scientific compute nodes
- Large-scale analytics and data processing
- AI data-preparation hosts
