HMAA4GR7CJR8N-XN Hynix 1x32GB DDR4 RDIMM ECC RAM

Enterprise DDR4 RDIMM Server Memory Upgrade featuring ECC Registered Architecture with the HMAA4GR7CJR8N-XN

The HMAA4GR7CJR8N-XN is a 32GB DDR4-3200 (PC4-25600E) ECC Registered RDIMM designed for enterprise servers that require predictable memory integrity and stable scaling across multi-DIMM channels. As a 288-pin buffered module, it supports platforms where registered signaling helps maintain electrical stability under higher population, improving reliability for dense virtualization and shared compute clusters.

Architected for DDR4 host systems, the HMAA4GR7CJR8N-XN aligns with modern CPU memory controllers that balance capacity per channel and bandwidth for mixed workloads. The 72-bit ECC data path protects against single-bit errors that can disrupt long-running processes, while CL22 timing targets consistent behavior under sustained utilization. In PCIe-centric servers with high I/O concurrency, correctly matched RDIMM memory reduces the likelihood of performance anomalies caused by memory retraining events, supporting storage-heavy nodes and analytics pipelines that depend on deterministic latency.

Why Choose the HMAA4GR7CJR8N-XN?

The HMAA4GR7CJR8N-XN provides a pragmatic density-to-performance step for DDR4 infrastructures, enabling clean capacity expansion without changing the server architecture. Its registered ECC design supports scalable memory topologies and operational resilience, making the HMAA4GR7CJR8N-XN well suited for standardized fleet deployments and controlled upgrade cycles across rack and blade estates.

Hynix focuses on tight process control and validation for server-grade memory, with an engineering approach centered on signal integrity, consistent SPD programming, and compatibility across mainstream enterprise platforms. This helps the HMAA4GR7CJR8N-XN integrate into data centre maintenance workflows that prioritize uptime, predictable behavior, and lifecycle-managed spares.
