NEMIX RAM DDR5 ECC RDIMM 256GB 8x32GB 4800MHz CL40 1.1V 2Rx8 Supermicro H14DSH

256 GB DDR5 ECC RDIMM kit for Supermicro H14DSH

This 256 GB kit contains eight 32 GB DDR5-4800 registered ECC modules built to the exact rank, voltage and timing the Supermicro H14DSH memory controller expects. It is intended for administrators who need to populate every slot at full rated capacity without compatibility surprises.

Registered 288-pin form factor with no heat spreader

Each module uses a 288-pin RDIMM layout that matches the board’s registered-DIMM requirement; a UDIMM or SODIMM will not fit. The registered architecture buffers the command bus so all eight slots can run fully populated at 4800 MT/s while ECC corrects single-bit errors on the fly, protecting data integrity in production workloads.

Replaces mismatched or undersized DDR5 kits

If the server currently runs a partial population, slower modules or a mix of ranks that force the controller to down-clock, this spec-matched kit restores full-speed operation across all channels. The jump is worth it when the platform’s population rules demand identical 2Rx8 modules at 1.1 V to reach the rated 256 GB capacity.
