NEMIX RAM
A 96GB kit of two 48GB DDR5 5600 CL46 unbuffered UDIMMs built for SuperMicro C9Z790-CG motherboards
This 96 GB kit contains two 48 GB DDR5 5600 UDIMMs built for the SuperMicro C9Z790-CG motherboard. It targets workstation and server builders who need maximum capacity in a two-slot configuration. The modules are unbuffered, non-ECC and validated for that specific platform.
The decisive specification is the CL46 timing at the rated 5600 MT/s data rate. This latency figure determines whether the memory meets the timing window required by the SuperMicro C9Z790-CG memory controller. Buyers who need tighter timings for latency-sensitive workloads should look elsewhere.
Running at 1.1 V, the modules draw minimal power and generate little heat despite the high density. No heat spreaders are fitted, so airflow across the bare PCB is sufficient for normal workloads. Acoustic impact is negligible because the kit adds no active cooling.

CL46 is the CAS latency figure; at 5600 MT/s the memory controller waits 46 clock cycles before the first data burst begins, which sets the baseline access delay for every read operation.
The DDR5 5600 PC5-44800 rating caps the peak transfer rate at 44800 MB/s per module; real-world bandwidth will be lower due to protocol overhead and system latency.
Yes, the kit uses the 288-pin DDR5 UDIMM form factor, which matches the physical slot and keying on compatible desktop motherboards such as the SuperMicro C9Z790-CG.
