NEMIX RAM 576GB 12x48GB DDR5 5600 CL46 ECC RDIMM Supermicro H14SSL-N memory upgrade

576GB DDR5 5600 ECC RDIMM kit

This 576GB kit contains twelve 48GB DDR5 5600 CL46 Registered ECC RDIMMs built for the Supermicro H14SSL-N motherboard. Each module runs at 1.1V with a 2Rx8 organisation and 288-pin form factor. The exact rank, voltage and timing match the board's memory controller so the full capacity is recognised at rated speed. It is not suited for systems that require UDIMM or SODIMM modules or that cannot accept Registered ECC memory.

Sustained load behaviour

Registered architecture buffers the address and command signals so all twelve slots can stay fully populated without overloading the memory controller. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during long-running workloads. The 1.1V operating voltage keeps power draw consistent across the full kit. Buyers who need higher frequencies or lower latencies than DDR5 5600 CL46 will not find them here.

Build and connectors

Modules ship without heat spreaders, relying on server chassis airflow for cooling. The 288-pin RDIMM edge connector fits only DDR5 Registered DIMM slots keyed for this form factor. Installation must follow the motherboard's approved population order to achieve full 576GB capacity. The kit contains exactly twelve modules; builders who need a different module count or a non-ECC configuration cannot use this package.
