NEMIX RAM 16GB DDR5 4800 CL40 1Rx8 1.1V ECC RDIMM Supermicro H13SSH memory upgrade

Exact-match DDR5-4800 RDIMM for Supermicro H13SSH

This 16 GB DDR5 4800 (PC5-38400) module is built as a 1Rx8 registered ECC RDIMM at 1.1 V CL40. It matches the rank, voltage and timing the Supermicro H13SSH memory controller expects so the server recognises the full capacity and runs at the rated speed. The 288-pin registered form factor is the one that board requires.

288-pin registered form factor and population rules

The RDIMM architecture buffers the command and address bus, letting every slot run fully populated at full capacity without overloading the controller. You must follow the motherboard manual for supported capacities, approved DIMM population order and installation steps before fitting the module. No heat spreader is fitted, so airflow in the chassis clears the chips directly.

Registered ECC stability under sustained load

Registered buffering offloads the memory controller during continuous operation while on-die ECC catches and corrects single-bit errors on the fly. This prevents silent data corruption and unplanned reboots from reaching production workloads. The module is backed by lifetime replacement coverage and US-based technical support for the service life of the hardware.
