HMAA4GR7AJR8N-XN Hynix 1x32GB DDR4 ECC RAM

High-Performance DDR4-3200 ECC RDIMM Server Memory Module for Capacity Expansion with the HMAA4GR7AJR8N-XN

The HMAA4GR7AJR8N-XN is a 32GB DDR4-3200 ECC Registered (RDIMM) module engineered for enterprise server platforms that require predictable memory behavior under virtualization and mixed general-purpose compute. Built to JEDEC PC4-25600R parameters, it supports stable operation in multi-socket CPU environments where registered signaling improves integrity and scalability across populated channels.

With a 288-pin, 1.2V design and 72-bit data width, the HMAA4GR7AJR8N-XN provides ECC protection to reduce the operational risk of soft errors in long-running workloads. Its dual-rank organization and CL22 timing profile help balance bandwidth and access latency for CPU-memory intensive services. By expanding installed memory capacity, the HMAA4GR7AJR8N-XN can alleviate PCIe and storage pressure created by paging, enabling more consistent I/O patterns for SSD-backed tiers and improved consolidation ratios for hypervisors and database nodes.

Why Choose the HMAA4GR7AJR8N-XN?

The HMAA4GR7AJR8N-XN aligns with standard DDR4-3200 RDIMM server designs, making it a practical building block for capacity scaling without changing CPU or platform topology. It supports high DIMM population strategies for better density-to-performance efficiency, while ECC and registered operation strengthen reliability for 24/7 service delivery. The HMAA4GR7AJR8N-XN also simplifies lifecycle planning as a consistent spare part across homogeneous fleets.

Hynix designs server memory with a focus on signal integrity, qualification discipline, and long-term availability aligned to modern data center validation practices. The HMAA4GR7AJR8N-XN reflects this approach through standards-based electrical characteristics and compatibility targets for enterprise platforms.
