HMA82GR7CJR8N-XN Hynix 1x16GB DDR4 ECC RAM

Enterprise DDR4 RDIMM Memory Module for ECC-Registered Server Platforms with the HMA82GR7CJR8N-XN

The HMA82GR7CJR8N-XN is a SK hynix 16GB DDR4 RDIMM engineered for server CPU platforms that rely on registered memory to scale capacity while maintaining signal integrity across multi-DIMM channels. In modern 2-socket x86 compute nodes, this ECC-protected, dual-rank x8 architecture supports stable memory training and predictable performance under sustained virtualization and database pressure.

Operating at DDR4-3200 JEDEC at 1.2V, the HMA82GR7CJR8N-XN aligns with balanced CPU-to-memory throughput for general-purpose compute, transactional workloads, and mixed I/O profiles. While PCIe generation and storage tiering define expansion and data placement, RDIMM reliability is foundational: ECC registration reduces error exposure and improves platform-level availability during heavy DMA, high queue-depth storage, and dense VM consolidation. The low-profile 288-pin form factor fits thermally constrained chassis without compromising serviceability.

Why Choose the HMA82GR7CJR8N-XN?

The HMA82GR7CJR8N-XN delivers a practical density-to-stability ratio for enterprises standardizing on DDR4 RDIMM fleets, enabling incremental capacity expansion without disrupting validated server baselines. It is suited for scale-out deployments where consistent JEDEC behavior, ECC integrity, and registered buffering help maintain uptime across large node counts and long maintenance cycles.

SK hynix designs memory for predictable interoperability in enterprise platforms, emphasizing JEDEC compliance, controlled component qualification, and manufacturing discipline aligned with modern data centre reliability targets. The HMA82GR7CJR8N-XN reflects this approach with ECC Registered operation and consistent timing behavior for production environments.

Key Applications:

• Server memory expansion
• Virtualization hosts
• Database and transactional systems
• General-purpose compute
