NEMIX RAM
A 64 GB DDR5 kit of four 16 GB unbuffered UDIMMs at 5600 MT/s, CL46, 1.1 V, validated for the SuperMicro C9Z790-CG motherboard
This 64GB kit contains four 16GB DDR5 5600 unbuffered non-ECC modules built for the SuperMicro C9Z790-CG motherboard. Each stick runs at 1.10V with CL46 latency and a 1Rx8 organisation. The set targets workstation and server builders who need validated capacity for that specific platform.
Confirm the motherboard accepts four 288-pin DDR5 UDIMMs at 5600 MT/s and that the BIOS recognises 1Rx8 density without ECC. The kit is not buffered or registered, so it will not work in slots requiring registered DIMMs. Check the manual for maximum per-slot capacity and population rules.
At 1.10V the modules draw minimal power and run without heat spreaders, so airflow across the slots is sufficient for normal workloads. Noise is limited to the system fans already present. The low voltage also reduces stress on the memory controller during sustained loads.

The package contains only the four 16 GB DDR5 5600 UDIMM modules; no cables, brackets or tools are included.
It provides 64 GB total capacity at DDR5 5600 with CL46 latency and 1.10 V operation, matching the SuperMicro C9Z790-CG qualified specification.
CL46 is the CAS latency rating; at 5600 MT/s it determines the minimum cycle delay before data becomes available after a read command.
