NEMIX RAM DDR5 256GB (4x64GB) 4800MHz ECC Registered RDIMM 2Rx4 CL40 1.1V Supermicro H13DSG-O-CPU

Exact-Match Server Upgrade

This NEMIX RAM kit delivers 256GB across four 64GB DDR5 modules built to the exact rank, voltage and timing the Supermicro H13DSG-O-CPU motherboard expects. Registered ECC RDIMM architecture ensures every slot runs fully populated at the rated 4800MHz speed with CL40 latency and 1.1V operation. The 2Rx4 organisation matches the board's memory controller requirements for reliable recognition at full capacity.

Who This Suits And Who Should Look Elsewhere

System administrators expanding a Supermicro H13DSG-O-CPU platform to its maximum supported memory with validated registered ECC modules will find this kit fits the board's population rules. Buyers who need unbuffered UDIMM or SODIMM form factors cannot use these 288-pin RDIMMs in workstation or laptop slots. Anyone requiring a different total capacity or speed grade should consult the motherboard manual for approved configurations before purchasing.

Sustained Load Behaviour

Registered buffering offloads the memory controller so all four slots maintain stability when fully populated under continuous enterprise workloads. ECC circuitry detects and corrects single-bit errors on the fly preventing silent data corruption during extended compute tasks. The 1.1V operating voltage keeps power draw consistent across long-running virtualisation, database or HPC sessions without thermal throttling from the memory subsystem.
