Server memory kit for registered ECC platforms

This NEMIX RAM kit delivers 768 GB of DDR5 capacity across six 128 GB registered DIMMs. It is built for enterprise servers and workstations that require error-correcting code and registered buffering. Standard desktop boards cannot use these modules.

Registered buffering and ECC protect data integrity

Each module operates at 1.1 V with a CAS latency of 52 and a 2Rx4 organisation. The registered design reduces electrical load on the memory controller, while ECC corrects single-bit errors in flight. These traits matter for virtualisation hosts, database nodes and other workloads that cannot tolerate silent corruption.

288-pin DDR5 form factor fits compatible server

The modules use the industry-standard 288-pin DDR5 RDIMM layout, so they install in any qualified server motherboard that supports DDR5 6400 registered memory. Buyers needing unbuffered DIMMs, non-ECC operation or desktop form factors should select a different product line.

Questions about this item

Will the 2Rx4 ECC RDIMM modules need any periodic replacement under normal server workloads?

The DDR5 modules are solid-state with no moving parts and carry a lifetime replacement warranty, so no scheduled replacement is required.

What thermal or power limit appears first when all six 128 GB sticks run continuously at 6400 MT/s?

Each module operates at 1.1 V and the registered 2Rx4 design distributes load across the memory controller, keeping power draw within the DDR5 6400 specification.

How much heat and fan noise should I expect from the 768 GB kit during 24/7 operation?

Registered DDR5 RDIMMs run at 1.1 V with no active cooling on the modules themselves; system airflow handles the heat and adds no audible noise.
