SuperMicro Compatible 256GB Kit

This NEMIX RAM kit delivers 256GB across eight 32GB DDR4 UDIMM modules built for SuperMicro desktop and SuperWorkstation platforms such as the 5039AD-I and MBD-C9X299-PGF. The 2933 MT/s PC4-23400 speed and CL21 latency suit memory-intensive workloads on supported workstations. It is not for systems that require ECC or registered DIMMs.

Tool-less DIMM Installation

Each 288-pin unbuffered module installs directly into standard DDR4 slots without additional hardware or cables. Align the notch, press until the latches click, and the firmware detects the 2Rx8 organisation automatically. Builders who need registered or load-reduced memory cannot use this kit.

Sustained Load Stability

Modules are stress tested under load at 1.20V to maintain timing consistency during extended compute sessions. The absence of a heat spreader means airflow across the PCB manages thermals in densely populated SuperMicro chassis. Systems without adequate case ventilation may see higher sustained temperatures.

Questions about this item

How can I verify the kit is running at 2933 MT/s after installation?

Open the system BIOS or use a tool such as CPU-Z to confirm the memory frequency reads 2933 and the timings show CL21 at 1.2 V.

What exactly ships in the box and is anything else required?

The package contains eight 32 GB DDR4 UDIMM modules for a total of 256 GB; no extra cables, brackets or software are needed.

Which capacity option should I pick for a SuperMicro board that supports 256 GB maximum?

Choose this 256 GB (8 x 32 GB) kit to fully populate the board and reach its supported memory limit.
