NEMIX RAM 288GB (6×48GB) DDR5-6400 CL52 1.1V ECC RDIMM Supermicro H13SSW memory upgrade

288GB DDR5-6400 ECC RDIMM kit for Supermicro H13SSW

This 288GB kit contains six 48GB DDR5-6400 registered ECC modules built to the Supermicro H13SSW memory specification. It targets administrators who need maximum capacity on this platform without mixing ranks or voltages. The registered design lets the memory controller drive every slot at the rated 6400 MT/s speed. Buyers who need non-ECC UDIMMs or SODIMM form factors cannot use this kit.

Verified fitment for Supermicro H13SSW motherboards

The kit matches the board's required 288-pin RDIMM form factor, 2Rx8 organisation, 1.1V operating voltage and CL52 latency. It replaces mismatched or lower-capacity modules that force the controller to down-clock or limit population. The jump is worth it when the manual confirms six-DIMM support at full speed and the workload demands the full 288GB at 6400 MT/s. Systems that only validate lower densities or different rank structures will not benefit.

Tool-free DIMM installation

Each module seats in the standard 288-pin DDR5 slot with the key notch aligned; no cables or drivers are involved. The most common issue is ignoring the motherboard's prescribed population sequence, which can prevent POST or reduce the memory to a lower speed. Another frequent error is mixing these registered ECC RDIMMs with unbuffered or non-ECC modules, which the platform will reject. Always consult the H13SSW manual for the exact slot order before installing all six sticks.
