SK Hynix DDR5 128GB 6400 MT/s RDIMM (HMAF16GR7AJR4N-WM) delivers CAS Latency 46 at just 1.1V, a critical combination for high-frequency trading platforms and in-memory database workloads where sub-microsecond latency directly impacts throughput. Running at PC5-51200 speed with dual-rank, x4 organization (2Rx4), this 288-pin RDIMM combines enterprise-grade error correction—both system-level ECC and on-die ECC per DDR5 specification—with the registered controller architecture required for 3rd-generation data center servers. The SK Hynix module operates across the full industrial temperature range (0–85°C) and adheres to JEDEC DDR5 RDIMM standards, ensuring compatibility with Intel Xeon Scalable Sapphire Rapids and newer, as well as AMD EPYC Genoa and successor platforms.

Data center architects, storage engineers, and AI infrastructure teams specify SK Hynix memory when capacity density and reliability cannot be compromised. At 128GB per module, organizations deploying large-scale analytics, machine learning inference clusters, or real-time transaction processing can populate servers with multiple sticks while maintaining tight voltage headroom and predictable latency profiles. The 1.1V operating voltage reduces power draw—a substantial operational cost factor in high-density environments—and the registered design isolates the memory bus from direct CPU attachment, improving signal integrity across multi-processor systems. SK Hynix's advanced 1b-nanometer DRAM process ensures yield consistency and long-term supply stability for critical enterprise deployments.

Omnixon Global stocks SK Hynix DDR5 modules for immediate availability across the UAE and GCC region, supporting both new-build data center projects and upgrade cycles for existing Xeon and EPYC environments.
