768GB DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit provides 768GB of DDR5 memory across six 128GB registered DIMMs. It operates at 4800 MT/s with CL40 latency and 1.1V voltage. The modules are built for Supermicro H13SVW-NT-OS1 motherboards that require 288-pin RDIMMs with ECC and registered buffering.

Suited for servers needing maximum registered ECC

The 2Rx4 organisation and registered design let the memory controller run all slots fully populated at the rated speed. ECC corrects single-bit errors on the fly to prevent silent data corruption. Builders using consumer boards, UDIMM-only platforms, or systems that cannot address 128GB per slot should look elsewhere.

128GB per module rank and voltage match the board

Each DIMM is a 2Rx4 device at 1.1V, the exact electrical profile the H13SVW-NT-OS1 memory controller expects. If your system manual lists a different rank structure, voltage, or maximum capacity per slot, the kit will not be recognised at full capacity or at its rated speed.

Questions about this item

Does the 1.1V DDR5-4800 kit run cool and quiet under 24/7 server loads?

Registered ECC RDIMM modules offload the memory controller so every slot stays stable at full capacity; with no heat spreader, airflow through the chassis handles the 1.1V modules.

What motherboard slot and population rules must my Supermicro H13SVW-NT-OS1 already have for this 6x128GB kit?

The board needs six free 288-pin DDR5 RDIMM slots and must support 2Rx4 registered ECC at 4800 MT/s; consult the manual for the exact population order.

Can I mix these 128GB 2Rx4 CL40 RDIMMs with smaller DDR5 ECC modules already in the server?

Mixing ranks or capacities is not recommended; the memory controller expects identical 2Rx4 registered ECC DIMMs in each channel for full-speed operation.
