512GB DDR5 4800 ECC RDIMM kit

This 512GB kit contains sixteen 32GB DDR5 4800 CL40 registered ECC modules built for Supermicro SuperWorkstation SYS-551A-T and Super X13SWA-TF systems. It targets IT professionals who need maximum registered memory capacity in validated server and workstation platforms.

Sustained load behaviour with registered ECC

Registered buffering and on-die ECC maintain data integrity during continuous multi-threaded workloads such as virtualisation, database serving and scientific computing. The 1.1V operating voltage and 1Rx4 organisation keep power draw predictable while the modules run at the rated 4800 MT/s under prolonged stress.

Installation notes for sixteen-module population

Populating all sixteen DIMM slots requires strict adherence to the motherboard population guide; incorrect slot order will prevent boot. The lack of heat spreaders eases fitment in dense chassis but demands adequate case airflow. Buyers who need fewer than sixteen modules or non-registered memory should choose a different kit.

Questions about this item

How much power does the 1.1V DDR5 kit draw when the Supermicro workstation runs continuously?

Each module operates at 1.1V, so the 16 x 32GB kit runs at standard DDR5 voltage; actual system draw depends on the Supermicro platform's memory controller and workload.

What motherboard slots and CPU memory channels are required for all sixteen 288-pin RDIMMs to be recognised?

The kit needs a Supermicro X13SWA-TF or SYS-551A-T motherboard with enough DDR5 RDIMM slots and CPU channels to populate all sixteen 288-pin sockets.

Will the CL40 registered DIMMs downclock if the Supermicro board only supports a lower DDR5 data rate?

Yes, the DDR5 4800 modules will negotiate the highest common speed with the motherboard, so they run at the board's maximum supported DDR5 rate.
