NEMIX RAM DDR5 6400 128GB (4x32GB) CL52 1.1V 2Rx8 ECC RDIMM Supermicro H13DSH memory upgrade

Capacity and form factor

This NEMIX RAM kit supplies 128 GB across four 32 GB DDR5 RDIMMs. Each module is a 288 pin registered ECC DIMM built for the Supermicro H13DSH motherboard. The 2Rx8 organisation and 1.10 V operation match the platform memory controller requirements exactly.

Upgrade path and fitment

The kit replaces any smaller or slower DDR5 RDIMM population that leaves slots empty or runs below the rated 6400 MT/s speed. A jump is worthwhile when the workload needs the full 128 GB capacity at the native data rate without down clocking. Builders using UDIMM or SODIMM modules cannot use this registered form factor.

Sustained operation behaviour

Registered buffering reduces electrical load on the memory controller so all four slots remain stable at full population. ECC corrects single bit errors continuously preventing silent data corruption during long running server tasks. The absence of a heat spreader means airflow across the modules must be adequate for continuous duty.
