Capacity and platform fit

This 192GB kit contains four 48GB DDR5 UDIMM modules built for the SuperMicro C9Z790-CGW motherboard. It targets workstations and servers that need large memory pools for virtualization, data analysis or AI workloads. The unbuffered non-ECC design matches the board’s consumer-style DIMM slots while delivering enterprise capacity.

Sustained-load behaviour

Modules use major OEM Samsung, Micron or Hynix chips rated at DDR5 5600 with CL46 latency and 1.10V operation. The 2Rx8 organisation keeps signal integrity stable during long compile jobs, database runs or model training sessions. Rigorous stress testing under load is performed before shipment to verify reliability in continuous operation.

Thermals noise and power

The kit runs at the standard DDR5 1.1V without a heat spreader, relying on case airflow for cooling. Unbuffered UDIMMs draw less power than registered alternatives, helping system fans stay quiet during typical workloads. No active cooling components are included so acoustic profile depends entirely on chassis ventilation.

Questions about this item

What power draw should I expect from this 1.10 V DDR5 5600 kit when the C9Z790-CGW runs all day?

Each 48 GB module operates at 1.10 V standard DDR5 voltage; total system power depends on the motherboard's memory controller and load, not on the kit alone.

Does the SuperMicro C9Z790-CGW need a specific BIOS version or CPU to recognise all four 48 GB UDIMMs?

The kit is validated for the C9Z790-CGW motherboard; the board's own CPU and BIOS requirements determine whether 192 GB is supported.

Will these 288-pin DDR5 5600 CL46 sticks run at rated speed alongside slower DDR5 modules already in the board?

The motherboard will clock all installed memory to the lowest common speed and latency; mixing kits may prevent 5600 operation.
