NEMIX RAM DDR5 5600 128GB (8×16GB) CL46 1.1V ECC Registered RDIMM Supermicro H13DSH memory upgrade

Exact-match DDR5 server upgrade

This 128GB kit delivers eight 16GB DDR5 5600 Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13DSH memory controller expects. Each module runs at 1.1V with CL46 latency and a 1Rx8 organisation so the board recognises the full capacity at rated speed. The 288-pin RDIMM form factor matches the slots this motherboard requires, not UDIMM or SODIMM alternatives. Spec-matched population rules mean every slot can be filled without guesswork.

Enterprise stability under load

Registered architecture buffers the command bus so the memory controller stays stable when all eight slots are populated at full capacity. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots before they reach production workloads. Operating at the standard 1.1V DDR5 voltage keeps power draw predictable in dense server configurations. No heat spreaders are fitted, allowing unrestricted airflow across the DRAM in chassis with directed cooling.

Build integration checklist

Verify your H13DSH manual for supported capacities, approved DIMM population order and installation steps before fitting the kit. The modules require 288-pin RDIMM slots and a platform that enables Registered ECC operation at DDR5 5600. Systems limited to UDIMM, SODIMM or non-ECC memory cannot use this kit. Buyers needing higher per-module density or non-registered memory should select a different specification.
