Hynix HMAA4GR7CJR8N-XN 32GB DDR4-3200 ECC REG DIMM accessory

Server-grade DDR4-3200 ECC module

The Hynix HMAA4GR7CJR8N-XN is a 32GB registered DIMM built for DDR4-3200 platforms that require error-correcting code memory. It targets system integrators and IT departments upgrading or repairing enterprise servers and workstations. The module is not intended for consumer desktop or laptop motherboards that lack ECC and registered-buffer support.

Registered buffer and ECC

The registered design places a buffer between the DRAM and the memory controller, reducing electrical load so larger capacities can be populated per channel. ECC circuitry detects and corrects single-bit errors, protecting data integrity in long-running compute tasks. No additional software, cables or brackets are included; the module installs directly into a compatible RDIMM slot.

32 GB capacity at 3200 MT/s

A single stick delivers 32 GB of addressable memory at the rated 3200 MT/s transfer rate, suitable for virtualisation hosts, database nodes and rendering farms that benefit from high density per slot. Systems limited to unbuffered UDIMMs or lower maximum densities cannot use this module, and platforms capped below DDR4-3200 will downclock the part.
