A-Tech 32GB DDR5-5600 ECC RDIMM 1Rx4 EC4 Hynix HMCG84AGBQA191N server RAM

32GB DDR5-5600 ECC RDIMM for servers

This 32GB registered DDR5 module runs at 5600MHz with a CAS latency of 40 and operates at 1.10V. It uses a 1Rx4 organisation and major-brand DRAM chips on a 288-pin form factor. The module is designed as a compatible replacement for the Hynix HMCG84AGBQA191N part number in server and workstation systems. Error-correcting code and registered buffering help maintain data integrity under heavy workloads.

ECC and registered buffering protect data integrity

Error-correcting code detects and corrects single-bit errors while the registered design reduces electrical load on the memory controller. Together they allow larger memory configurations to run reliably in multi-socket platforms. The 1Rx4 layout and major-brand ICs support consistent signalling at the rated 5600MHz speed. No heat spreader is fitted, so airflow in the chassis must be sufficient to keep the module within thermal limits.

Verify DDR5 RDIMM support and slot population rules

Confirm that your motherboard and processor support DDR5 registered DIMMs at 5600MHz and that the BIOS recognises 1Rx4 modules. Check the system manual for correct slot population order and maximum capacity per channel. Registered memory cannot be mixed with unbuffered modules and will not function in platforms that require UDIMMs or earlier DDR generations. Ensure the 288-pin keying matches the DIMM sockets before ordering.
