SK hynix HMAA4GR7AJR8N-XN 32G DDR4 3200 RDIMM
The SK hynix HMAA4GR7AJR8N-XN is a 32GB DDR4-3200 ECC Registered DIMM built for enterprise servers, data center platforms, virtualization hosts, and storage systems. It suits system integrators and IT procurement teams standardizing on JEDEC-compliant RDIMMs for dual-socket or multi-node deployments. As with all registered DDR4, confirm your platform supports DDR4 RDIMMs specifically — they cannot be mixed with UDIMMs, LRDIMMs, or DDR5 modules on the same board.

Good to know
- Compatibility: RDIMMs require a registered-DIMM-capable server or workstation platform; mixing RDIMMs with UDIMMs or LRDIMMs on the same channel is not supported, and achievable data rate (3200 MT/s vs lower) may depend on CPU generation and channel population.
- Within the family: The 2Rx8 dual-rank, x8 DRAM configuration offers a balance of density and performance in SK hynix’s DDR4 RDIMM lineup, suited to virtualization hosts and storage/cache workloads where ECC reliability and sustained bandwidth matter.
- Buying tip: For multi-module servers, order modules from the same speed grade and rank configuration to simplify channel population and avoid downclocking across mixed kits.
