About the SK Hynix DDR5 256GB 4800 MT/s LRDIMM
A single SK Hynix DDR5 256GB LRDIMM enables enterprise servers to reach maximum memory capacity of 24TB or more per system—a critical ceiling for hyperscale infrastructure. The HMAF32GR7MJR4N-XN operates at 4800 MT/s (PC5-38400) with dual independent 32-bit sub-channels, delivering the bandwidth modern data centers demand. SK Hynix engineered this module with on-die ECC plus registered ECC protection, load-reducing RCD and data buffer components, and 8-rank configuration optimized for Intel Xeon Scalable processors running Sapphire Rapids and later generations. Storage architects and data center infrastructure teams specify this LRDIMM to consolidate workload density while maintaining signal integrity across high-capacity memory planes.
Built to JEDEC DDR5 standards with 1.1V operation and burst length BL16, the SK Hynix 256GB LRDIMM excels in environments where memory modularity and reliability cannot compromise performance. The 288-pin form factor integrates seamlessly into standard server platforms, while the 0–85°C operating range supports varied thermal profiles across global facilities. Whether deployed individually or in multi-module configurations, this module addresses the memory appetite of next-generation virtualization, analytics, and AI-driven applications.
