Exact-match server upgrade

This NEMIX RAM kit delivers 384 GB across four 96 GB DDR5 RDIMMs built for the Supermicro H14SST-GE motherboard. Registered ECC modules with 2Rx4 organisation provide the precise rank structure and voltage the platform expects.

Thermals and power

Modules operate at 1.10 V with no heat spreaders, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller when all slots are populated. Power draw scales with the 6400 MT/s data rate under typical enterprise workloads.

Capacity gate

The 384 GB total capacity is the single specification that determines fitment; the board must support this density in a four-DIMM configuration. Buyers needing lower capacity or unbuffered UDIMMs should select a different kit.

Questions about this item

How do I install the four 96GB DDR5 RDIMM modules in the Supermicro H14SST-GE, and which slot order does the manual require?

Power down the server, open the chassis, and insert each 288-pin module into the exact DIMM sequence shown in the motherboard manual; the registered design only works when every slot follows the board's population rules.

What maintenance or replacement will the 384GB DDR5 ECC RDIMM kit need over its service life?

No scheduled maintenance is required; if a module fails the lifetime replacement warranty covers a direct swap of the defective 96GB stick.

What limit appears first when the 4x96GB DDR5-6400 kit runs sustained workloads at 1.1V?

The registered buffer and ECC logic keep every slot stable at the rated 6400 MT/s, so the first constraint is the motherboard's maximum supported capacity rather than memory speed or voltage.
