About the SK Hynix DDR5 64GB 5600 MT/s RDIMM
SK Hynix DDR5 64GB 5600 MT/s RDIMM — next-generation registered memory for high-performance data centre infrastructure. The HMAA8GR7AJR4N-VK module delivers 5600 MT/s throughput at PC5-44800 speed, purpose-built for Intel Xeon Scalable 4th Gen (Sapphire Rapids) and AMD EPYC 4th Gen (Genoa) platforms.
This SK Hynix 64GB RDIMM combines on-die ECC (ODECC) with system-level error correction, ensuring mission-critical reliability in multi-socket server deployments. Operating at a power-efficient 1.1V with CAS latency 46, the module supports demanding workloads while maintaining thermal stability across 0°C to 85°C environments. As a registered (buffered) 288-pin DIMM with 8Rx4 organisation, it integrates seamlessly into high-capacity memory configurations without signal degradation. IT infrastructure teams and storage architects typically evaluate SK Hynix DDR5 modules for hyperscale cloud environments, virtualisation clusters, and analytics platforms requiring fast random access and large working sets.
Ideal Enterprise Deployment Scenarios
- Database servers running high-throughput transactional workloads with real-time consistency requirements
- Virtualisation hosts consolidating multiple guest operating systems with low latency tolerance
- In-memory caching and NoSQL clusters demanding sub-100ns response times
- HPC and scientific computing environments processing large datasets across distributed memory
- AI model training and inference pipelines requiring predictable bandwidth and ECC protection
The HMAA8GR7AJR4N-VK is validated for enterprise-grade uptime and backward compatibility with next-generation Intel and AMD socket platforms. For specifications, compatibility verification, or bulk procurement of SK Hynix DDR5 memory modules, contact Omnixon Global to request a formal quotation.
