About the SK Hynix DDR5 32GB 4800 MT/s RDIMM
SK Hynix DDR5 32GB 4800 MT/s RDIMM (part number HMAA4GR7AJR4N-XN) is engineered for Intel Xeon Scalable 4th Generation (Sapphire Rapids) and AMD EPYC 9004 Series (Genoa) platforms, delivering high-bandwidth memory performance across dual independent 32-bit sub-channels. This registered DIMM combines 32GB capacity with 4800 MT/s throughput at PC5-38400 rating, making it ideal for data center environments where memory density and reliability are non-negotiable. Storage architects and AI infrastructure teams rely on SK Hynix modules for mission-critical workloads demanding ECC protection and thermal stability.
The HMAA4GR7AJR4N-XN operates at just 1.1V with integrated on-module Power Management IC, reducing overall system power consumption while maintaining stable performance across operating temperatures from 0°C to 85°C. Dual-rank (2Rx4) x4 organization with 288-pin connectivity ensures compatibility with next-generation server architectures, while on-die ECC and CAS latency of CL40 (40-39-39-76 timings) protect data integrity in high-availability deployments. SK Hynix engineering delivers proven reliability in hyperscale cloud, HPC, and transactional database environments where downtime carries substantial business cost.
Typical Enterprise Deployment Scenarios
- Large-scale virtualization platforms requiring maximum memory density per socket without sacrificing error correction
- High-performance computing clusters running scientific simulation, genomics analysis, or financial modeling
- Data warehouse and OLAP environments where memory bandwidth directly impacts query throughput
- AI model training infrastructure needing consistent, ECC-protected memory across distributed GPU clusters
- Mission-critical database servers (Oracle, SQL Server, PostgreSQL) demanding registered DIMM stability and hot-swap capability
