576GB DDR5 RDIMM kit for Supermicro H13SSL-NT

This twelve-module kit delivers 576GB of DDR5-6400 registered ECC memory built for the Supermicro H13SSL-NT motherboard. Each 48GB module uses a 2Rx8 organisation and runs at 1.1V with CL52 latency. The 288-pin RDIMM form factor matches the board's registered DIMM slots exactly. It is not for systems that require unbuffered UDIMMs or SODIMM modules.

Capacity and headroom

Twelve 48GB modules populate every DIMM slot to reach the full 576GB capacity the board supports. Registered buffering allows all slots to run fully populated at the rated 6400 MT/s without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption under sustained loads. Workloads exceeding this total capacity or needing higher frequencies will require a different platform.

288-pin RDIMM form factor

The kit uses the 288-pin registered DIMM form factor mandated by the Supermicro H13SSL-NT memory controller. Unbuffered or SODIMM modules will not fit and cannot be recognised by this board. Confirm your motherboard manual for approved population order before installation.
