NEMIX RAM 512GB (4×128GB) DDR5 6400 CL52 ECC Registered RDIMM Supermicro H13SST-GC memory upgrade

Exact-match DDR5-6400 kit for Supermicro H13SST-GC

This 512 GB kit contains four 128 GB DDR5-6400 RDIMMs built to the CL52 1.1 V 2Rx4 specification the Supermicro H13SST-GC memory controller expects. Registered ECC architecture lets every slot run fully populated at rated speed while correcting single-bit errors on the fly. System integrators upgrading that specific motherboard get a drop-in solution without manual timing adjustments.

Thermals noise and power draw

Operating at 1.1 V, the modules draw minimal power for their density and run without a heat spreader, relying on the server chassis airflow. Registered buffering reduces electrical load on the memory controller, keeping temperatures stable even with all four slots populated. No active cooling is included, so adequate case airflow is required for sustained workloads.

What the bundle changes

The kit delivers four matched RDIMMs in a single package, eliminating the guesswork of mixing ranks or voltages across channels. ECC and registered signalling together prevent silent data corruption and unplanned reboots in production environments. Buyers needing a different capacity, a UDIMM form factor, or non-ECC memory cannot use this kit.
