NEMIX RAM
A 768GB DDR5 server memory kit of six 128GB registered ECC RDIMMs running at 6400MHz with 1.1V voltage and CL52 latency
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.
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.
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.

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