NEMIX RAM
A 128 GB DDR5 registered ECC kit (2 × 64 GB) running at 6400 MHz CL52, 1.1 V, 4Rx4, validated for Supermicro X14SBM-TP4F servers
This 128GB kit delivers two 64GB DDR5 ECC RDIMM modules for Supermicro X14SBM-TP4F systems. It targets server and workstation operators who need registered memory with error correction for sustained workloads.
Each module uses a 288-pin DDR5 RDIMM form factor with 4Rx4 organisation and operates at 1.10V. The design omits a heat spreader, so airflow across the DIMM slots must be sufficient for the operating environment.
The kit replaces smaller-capacity or lower-speed DDR5 RDIMM sets when the platform supports 6400MHz CL52 registered modules. The jump is worthwhile when the application demands 128GB of ECC memory and the motherboard qualifies this exact part number.

Yes, the kit runs at 6400MHz which equals PC5-51200 transfer rate, so that is the practical ceiling for this memory.
Each 64GB module uses a standard 288-pin DDR5 RDIMM form factor and requires a matching registered DIMM slot on the Supermicro X14SBM-TP4F motherboard.
Power down the server, open the chassis, align each module's notch with the slot key, press firmly until the retention clips lock, then verify the BIOS recognises the full 128GB capacity.
