NEMIX RAM DDR5 5600 768GB 6x128GB CL46 ECC RDIMM Supermicro H13SSW

Capacity and fit

This 768GB kit delivers six 128GB DDR5 5600 RDIMM modules built to the exact rank, voltage and timing the Supermicro H13SSW motherboard expects. Registered ECC architecture allows every slot to be fully populated at rated speed while correcting single-bit errors on the fly. The 288-pin form factor matches the board’s memory slots without adapters or down-clocking. Builders using other platforms or unbuffered memory should look elsewhere.

Sustained operation

Registered buffering offloads the memory controller so all six modules run continuously at 5600 MT/s without the signal degradation that limits unbuffered kits at full population. ECC corrects single-bit errors in real time, preventing silent data corruption during long compute runs or database workloads. The 2Rx4 organisation and CL46 latency are maintained across the full 768GB capacity under constant load. Systems that require higher frequencies or lower latencies will not achieve them with this kit.

Thermals and power

Modules operate at 1.10V without heat spreaders, relying on the server chassis airflow for cooling. The registered design reduces electrical load on the motherboard’s memory controller, keeping power draw predictable during sustained throughput. Acoustic profile is determined entirely by the system fans; the memory itself adds no moving parts. Environments with restricted airflow or no forced cooling may exceed safe operating temperatures.
