NEMIX RAM DDR5 6400 ECC RDIMM 768GB 6x128GB CL52 1.1V 2Rx4 Supermicro H14SSL-NT memory upgrade

Exact-match DDR5 kit for Supermicro H14SSL-NT

This 768GB kit contains six 128GB DDR5 RDIMMs built to the exact rank, voltage and timing the Supermicro H14SSL-NT memory controller expects. Registered ECC architecture lets every slot run fully populated at rated speed while correcting single-bit errors on the fly. It is not for systems that require UDIMM or SODIMM form factors.

2Rx4 registered ECC at CL52 1.1V

Each module is a 288-pin DDR5 RDIMM rated at 6400 MT/s (PC5-51200) with CAS latency 52 and 1.10V operating voltage. The 2Rx4 organisation and registered buffer match the board's population rules so the full 768GB is recognised without down-clocking. Buyers whose platforms demand a different rank structure or voltage cannot use this kit.

Low-voltage DDR5 thermals

Running at 1.1V keeps power draw modest even with all six slots populated, so standard server airflow handles thermals without extra cooling. No heat spreaders are fitted, relying on the chassis directed airflow design. Systems with restricted ventilation or passive-only cooling should verify thermal headroom before installing a fully populated configuration.
