256GB DDR5 ECC RDIMM kit for Supermicro H13SVW-NT

This 256GB kit contains four 64GB DDR5-4800 registered ECC RDIMMs built for the Supermicro H13SVW-NT motherboard. Each module runs at 1.1V with CL40 timing and a 2Rx4 organisation. The registered design and error-correcting code suit enterprise workloads that demand data integrity and full-capacity operation across all populated slots.

Registered 288-pin form factor fits the board's

The modules use the 288-pin RDIMM form factor required by the H13SVW-NT, not UDIMM or SODIMM. Registered buffering reduces electrical load on the memory controller, allowing all four slots to run fully populated at the rated 4800 MT/s. ECC circuitry corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production environments.

Four 64GB modules deliver 256GB total capacity

The kit provides 256GB of DDR5 memory, suitable for virtualisation, database and compute tasks that benefit from large per-socket capacity. Headroom ends when the motherboard's maximum supported memory or population rules are reached, so the system manual must be consulted for approved DIMM configurations and any capacity limits beyond this kit.

Questions about this item

What is the maximum capacity the Supermicro H13SVW-NT motherboard can address with this 256GB DDR5-4800 ECC RDIMM kit?

The kit provides 256GB across four 64GB modules; the motherboard's manual defines the absolute ceiling and the required population order for full recognition.

How much power does each 64GB DDR5-4800 RDIMM draw at the rated 1.1V during continuous server workloads?

Each module operates at 1.1V; total system power depends on the platform's memory controller and the number of populated slots under sustained load.

Which motherboard feature must already be present for this 288-pin Registered ECC DDR5 memory to function?

The Supermicro H13SVW-NT must support 288-pin DDR5 RDIMM slots with Registered ECC capability; UDIMM or SODIMM slots will not accept these modules.
