NEMIX RAM 384GB 12x32GB DDR5 6400MHz CL52 1.1V ECC Registered RDIMM Supermicro H14SSL-N memory upgrade

Capacity and form factor

This 384GB kit contains twelve 32GB DDR5 RDIMM modules built for the Supermicro H14SSL-N motherboard. Each module uses a 288-pin registered design with ECC and operates at 1.1V. The 2Rx8 organisation matches the board's memory controller requirements for full-slot population.

Upgrade path and fitment

The kit replaces any lower-capacity DDR5 RDIMM configuration on the H14SSL-N when the workload demands the maximum supported module count. Registered buffering offloads the controller so all twelve slots run at the rated 6400MHz without signal degradation. ECC corrects single-bit errors in flight, preventing silent corruption that unbuffered memory cannot catch.

Headroom and limits

Twelve dual-rank modules deliver the full 384GB at CL52 latency, suitable for large in-memory databases and virtualization clusters. The fixed 1.1V operating voltage and registered topology mean the kit cannot be used in consumer UDIMM platforms or boards limited to fewer than twelve slots. Buyers needing higher per-module density or non-ECC operation must choose a different product.
