NEMIX RAM 64GB DDR5 6400 CL52 2Rx4 ECC Registered RDIMM 288-pin memory upgrade for Supermicro H14SSL-NT

Exact-match 64 GB DDR5 RDIMM for Supermicro

This NEMIX RAM module is a 64 GB DDR5-6400 Registered ECC RDIMM built to the precise rank, voltage and timing the Supermicro H14SSL-NT memory controller expects. It installs in a 288-pin slot and operates at 1.1 V with CL52 latency. The 2Rx4 organisation and registered architecture allow every supported slot to run fully populated at the rated speed. It is intended for administrators who need guaranteed recognition and full-capacity operation on this specific motherboard.

Replaces mixed-speed or lower-capacity DDR5 RDIMMs

When existing modules run at a slower data rate, use a different rank configuration or lack ECC, this kit restores uniform 6400 MT/s throughput and registered buffering across all populated channels. The jump is worth it when the server must hold the maximum supported memory per slot without down-clocking or stability compromises. Buyers who need a different capacity per DIMM, a UDIMM form factor or non-ECC memory should look elsewhere because this part is fixed at 64 GB, 2Rx4, registered ECC.

Verify motherboard manual for population rules

Before ordering, confirm the H14SSL-NT manual for approved DIMM population sequences, maximum capacity per channel and any BIOS version requirements for 6400 MT/s operation. The registered RDIMM form factor is mandatory; UDIMM or SODIMM modules will not fit or function. Ensure the system power budget accommodates the additional modules and that the chassis provides sufficient airflow for dense memory configurations.
