NEMIX RAM 768GB DDR5-6400 ECC RDIMM Kit

This 768GB kit contains six 128GB DDR5-6400 registered ECC RDIMMs built for the Supermicro H14DSG-OD motherboard. It targets server administrators who need maximum memory capacity across all available DIMM slots. The modules match the board's required 288-pin RDIMM form factor and 2Rx4 rank structure. Buyers needing unbuffered UDIMMs or smaller capacities should look elsewhere.

Sustained Load Behaviour with Registered ECC

Registered buffering reduces electrical load on the memory controller so all six slots operate at the rated 6400 MT/s when fully populated. ECC detects and corrects single-bit errors during continuous operation, preventing silent data corruption. The 1.1V operating voltage and CL52 latency are maintained under sustained throughput. Workloads that exceed the 768GB total capacity will still require swap or a different platform.

DDR5 RDIMM Interface Limits

The DDR5 RDIMM standard used here tops out at the 6400 MT/s data rate and 288-pin physical interface supplied. Registered DIMMs cannot be mixed with unbuffered UDIMMs in the same system. Population rules defined by the H14DSG-OD manual dictate which slots must be filled first. Systems requiring higher speeds, different voltages, or non-ECC memory cannot use this kit.

Questions about this item

How much power does the 1.1V DDR5 6400 kit draw when the server runs all day?

Each module operates at 1.10V; total system power depends on the Supermicro H14DSG-OD memory controller and workload, so consult the board manual for platform-level figures.

What must the motherboard provide for the 288-pin RDIMMs to function?

The Supermicro H14DSG-OD must support DDR5 6400 registered ECC memory with 2Rx4 organisation and 1.10V operation across all populated slots.

Can I mix these 128GB 2Rx4 modules with smaller capacity RDIMMs already installed?

Mixing ranks or capacities is governed by the H14DSG-OD population rules; check the motherboard manual for approved DIMM configurations before adding this kit.
