NEMIX RAM DDR5 6400 128GB 2x64GB 4Rx4 CL52 1.1V RDIMM Supermicro X14SDI-36C-SP3F

128 GB DDR5 RDIMM kit for Supermicro X14SDI-36C-SP3F

This 128 GB kit contains two 64 GB DDR5 6400 registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro X14SDI-36C-SP3F memory controller expects. The 4Rx4 organisation and 1.10 V operation match the board's population rules so the full capacity is recognised at rated speed. It is not for systems that require unbuffered UDIMMs or a different DDR generation.

Thermals noise and power at 1.10 V

Operating at 1.10 V the modules draw minimal power and run without a heat spreader, relying on the server's forced-air chassis cooling. Registered buffering reduces electrical load on the memory controller, helping keep the memory subsystem stable when every slot is populated. No active cooling or acoustic profile is specified for the DIMMs themselves.

What the kit changes for your server

The two-module kit populates a matched pair of slots, enabling the board's registered ECC architecture to correct single-bit errors on the fly and prevent silent data corruption. Exact-match specifications mean the firmware initialises the memory at DDR5 6400 without manual tuning. Buyers who need a different capacity or unbuffered memory must select another part.
