NEMIX RAM 128GB DDR5 5600 CL46 2Rx4 RDIMM ECC Supermicro H14SST-G memory upgrade

Exact-match DDR5 upgrade

This 128GB NEMIX RAM module delivers DDR5 5600 speed with CL46 latency and 1.1V operation in a 288-pin RDIMM form factor. It targets administrators upgrading the Supermicro H14SST-G motherboard who need registered ECC memory that the controller recognises at full capacity. The 2Rx4 organisation matches the board's population rules so every populated slot runs at the rated 5600 MT/s without down-clocking.

Replaces mismatched or smaller DIMMs

The kit replaces modules that lack the correct rank, voltage or registered buffer, which cause the system to ignore capacity or fall back to lower speeds. The jump is worth it when the server must run all slots populated at the full 128GB per module with on-the-fly error correction preventing silent data corruption. Builders using unbuffered UDIMMs or SODIMMs cannot use this part because the motherboard requires the registered RDIMM interface.

Fits the H14SST-G memory subsystem

The module slots directly into the 288-pin DDR5 RDIMM sockets on the Supermicro H14SST-G and draws 1.1V from the platform supply. Its registered architecture offloads the memory controller, freeing electrical headroom when the board is fully populated. Users must still consult the motherboard manual for approved population order and maximum supported capacity per slot before installation.
