NEMIX RAM
A 16 GB DDR4 3200 UDIMM module built for SuperMicro MBD-C9Z590-CGW workstations, running at CL22 and 1.2 V
This 16GB DDR4 3200 module is built for the Supermicro MBD-C9Z590-CGW motherboard. It runs at 1.2V with CL22 latency and a single-rank 1Rx8 layout. The unbuffered non-ECC design suits desktop and workstation boards that accept standard UDIMMs. No heat spreader is fitted.
Rigorous stress testing under load is performed on every module before shipment. The 1.2V operating voltage and CL22 timing remain stable during extended workloads. Unbuffered operation avoids the extra latency of registered designs. Single-rank organisation helps keep signal integrity consistent across long sessions.
Confirm the motherboard is the exact Supermicro MBD-C9Z590-CGW model. Verify the board has a free 288-pin DDR4 UDIMM slot and supports non-ECC unbuffered memory at 3200 MT/s. Ensure the system does not require ECC or registered modules. Check the manual for maximum capacity per slot and total system limit.

The module operates at 1.20V, the standard DDR4 voltage, so power draw stays low even under sustained load.
It requires a DDR4 288-pin UDIMM slot on a Supermicro MBD-C9Z590-CGW or compatible board that supports non-ECC unbuffered memory.
The system will clock all modules to the slowest speed and loosest timing, so this CL22 3200MHz module will downclock to match older DDR4 sticks.
