NEMIX RAM 128GB DDR5 6400MHz ECC RDIMM

This 128GB DDR5 module runs at 6400MHz with CL52 latency and 1.1V operation. It uses a 288-pin Registered RDIMM form factor with 4Rx4 rank configuration. The ECC Registered design targets server and workstation platforms requiring data integrity. ||

Verified Supermicro X14SRA-T compatibility

This memory is validated for the Supermicro X14SRA-T motherboard at DDR5 6400MHz PC5-51200. The 4Rx4 Registered ECC specification matches the board's memory controller requirements for full-capacity recognition. Installed modules operate at rated speed when populated per the motherboard manual. ||

Registered ECC architecture for thermal stability

The Registered buffer reduces electrical load on the memory controller during full-slot population. ECC corrects single-bit errors without system interruption. Operating at 1.1V standard DDR5 voltage, the module runs without a heat spreader in typical server airflow configurations.

Questions about this item

What does the 6400MHz speed mean once this module is installed in my Supermicro X14SRA-T?

The module runs at DDR5 6400 (PC5-51200) when the motherboard's memory controller is configured for that data rate, delivering the rated throughput at CL52 latency.

How does the 288-pin RDIMM interface and registered design affect what the board can do?

The 288-pin Registered RDIMM form factor is required by the X14SRA-T; the registered architecture buffers address and command signals so every slot can be fully populated at 128GB per module.

What physical clearance and power does this 128GB stick need to fit and run?

It uses the standard 288-pin DDR5 RDIMM height with no heat spreader, draws 1.1V, and fits the X14SRA-T DIMM slots without extra clearance.
