512GB DDR5 ECC RDIMM kit

This 512GB kit contains four 128GB DDR5 registered DIMMs rated at 5600MHz with CL46 latency. It is built for Supermicro X13SEI-F and X13SEI-TF motherboards in server and workstation roles. The modules operate at 1.1V and use a 4Rx4 organisation with ECC for data integrity.

Four-module registered kit

The package delivers four matched 128GB RDIMMs so the memory controller sees a single qualified population. Registered buffering reduces electrical load on the Supermicro platform, while on-die ECC corrects single-bit errors without software overhead. No heat spreaders are included, so airflow must handle thermal dissipation.

DDR5 5600 registered limits

DDR5 at 5600MHz PC5-44800 provides the rated bandwidth only when the motherboard and CPU memory controller support that speed. Registered 4Rx4 modules add a clock cycle of latency versus unbuffered DIMMs, and the CL46 timing reflects that overhead. The 1.1V operating voltage is fixed by the DDR5 standard for this data rate.

Questions about this item

Will the four 128 GB ECC RDIMM modules need replacement after continuous server operation?

The modules are built with major OEM Samsung, Micron or Hynix chips and carry a lifetime replacement warranty from NEMIX RAM.

What limit appears first when the 512 GB kit runs at DDR5 5600 CL46 under sustained load?

The registered 4Rx4 design and 1.10 V operation keep electrical loading within the DDR5 5600 (PC5-44800) specification during heavy workloads.

How much heat and noise do the 288-pin RDIMMs produce when the system runs all day?

The modules have no heat spreader and run at standard 1.1 V DDR5 voltage, so thermal output is low and they add no audible noise.
