NEMIX RAM
128 GB kit of four 32 GB DDR5 modules running at 5600 MT/s with CL46 latency and 1.1 V operation, built for the SuperMicro C9Z790-CGW motherboard
This 128GB kit is built for the SuperMicro C9Z790-CGW motherboard. It targets workstation users who need maximum memory capacity on a single consumer-platform board. The four 32GB modules fill every slot to reach the platform limit.
The modules run at DDR5 5600 with CL46 latency and 1.10V operation. Major OEM Samsung, Micron or Hynix components are used throughout. No heat spreaders are fitted, so airflow in the chassis handles cooling.
Four dual-rank 2Rx8 UDIMMs provide 128GB of non-ECC memory. This density suits large datasets, virtual machines and AI workloads that fit in system RAM. Workloads needing ECC protection or more than four slots cannot use this kit.

No firmware updates or scheduled re-seating are required for the 2Rx8 DDR5 modules once installed correctly.
The 5600 MT/s bus speed sets the peak bandwidth ceiling; CL46 latency affects access time but does not cap sustained throughput.
At 1.1 V the modules run cool enough for standard case airflow; no heat spreaders are fitted, so ordinary chassis fans are sufficient.
