Server memory kit for enterprise workloads

This NEMIX RAM kit delivers 512GB of DDR5 capacity across sixteen 32GB registered DIMMs. It is built for servers that require error-correcting code memory and registered signalling. The modules are not compatible with standard desktop or workstation platforms.

DDR5 6400 registered ECC specification

Each module operates at DDR5 6400 speed with a CAS latency of 52 and runs at 1.1V. The 2Rx8 organisation and 288-pin RDIMM form factor ensure compatibility with qualified server motherboards that support this exact registered ECC configuration.

Low-voltage operation for dense deployments

The 1.1V operating voltage helps reduce power draw per module when all sixteen DIMMs are populated. Registered buffering and ECC functionality add minimal overhead while maintaining signal integrity across full memory channels. Thermal output scales with total capacity and sustained bandwidth utilisation.

Questions about this item

Will the 6400 MT/s speed run at that rate in my server?

The modules are rated for DDR5 6400 (PC5-51200). Actual speed depends on the CPU memory controller and the number of DIMMs populated per channel; the system will negotiate the highest common rate.

Is this kit compatible with standard DDR5 RDIMM slots?

Yes, each module uses the 288-pin DDR5 RDIMM form factor and is electrically registered, matching the server DIMM socket specification.

How much clearance do the 16 modules need in a 2U chassis?

Each stick is a standard-height 288-pin RDIMM; 16 modules occupy 16 DIMM slots, so the board must provide that many sockets and enough vertical space for the registered heat spreader.
