A-Tech 64GB DDR5 5600 ECC RDIMM 2Rx4 HMCG94AGBRA181N

Server-grade capacity for heavy workloads

This 64GB DDR5 module targets servers and workstations that need large memory pools for virtualization, databases or compute clusters. The registered design with ECC protects data integrity in always-on environments. It replaces Hynix HMCG94AGBRA and HMCG94AGBRA181N part numbers. Systems requiring lower capacities or unbuffered memory should look elsewhere.

Sustained throughput at standard voltage

Rated at 5600 MT/s with CL40 latency, the module runs at 1.10V under continuous load. The 2Rx4 organisation and registered buffer help maintain signal quality across full DIMM populations. Error-correcting code detects and corrects single-bit errors without halting the workload. Builds needing higher frequencies or lower latencies are not addressed by this specification.

288-pin registered DIMM with major-brand chips

The 288-pin form factor fits standard DDR5 RDIMM slots in compatible server boards. Major-brand chipset components are used throughout. A-Tech validates each unit through quality-assurance testing before shipment. Lifetime warranty and US-based technical support are included. Buyers whose platforms demand unbuffered UDIMMs or a different pin count cannot use this module.
