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.

Questions about this item

Will these 288-pin RDIMMs fit the Supermicro H13DSH motherboard slots?

Yes, the kit uses the 288-pin RDIMM form factor required by the H13DSH and is verified for that board.

What is the correct population order when installing all four 32 GB modules?

Consult the H13DSH manual for the approved DIMM population sequence; the board's rules dictate which slots to fill first for full 128 GB operation.

Do the modules need active cooling since they have no heat spreader?

The modules ship without a heat spreader; ensure the server chassis provides adequate airflow over the DIMM slots for stable operation.
