768GB DDR5 RDIMM kit for Supermicro H13SSH-E

This 768GB kit contains twelve 64GB DDR5-4800 registered ECC modules built to the exact voltage, rank and timing the Supermicro H13SSH-E motherboard expects. It is intended for administrators who need the full 12-slot population recognised at rated speed without manual tuning.

Registered 2Rx4 ECC at 1.1V CL40

The modules are 288-pin DDR5 RDIMMs with a 2Rx4 organisation, 1.10V operating voltage and CL40 latency. Registered buffering and on-die ECC allow all twelve slots to run fully populated at the rated 4800 MT/s while correcting single-bit errors before they reach the operating system.

Twelve 64GB modules fill every slot

The kit delivers 768GB total capacity across the board's twelve DIMM sockets, reaching the maximum supported density per slot for this platform. Workloads requiring more memory than twelve 64GB RDIMMs provide will need a motherboard with additional channels or higher-density modules.

Questions about this item

How does the 4800 MT/s speed translate once the kit is installed in the Supermicro H13SSH-E?

The modules run at DDR5-4800 (PC5-38400) with CL40 latency at 1.1 V, delivering the exact data rate and timing the board's memory controller expects for full-capacity operation.

What does the registered ECC RDIMM interface provide in this configuration?

Registered buffering reduces electrical load on the controller so all twelve slots can be populated, while ECC detects and corrects single-bit errors to prevent silent data corruption.

Will the 288-pin RDIMM modules fit the Supermicro H13SSH-E memory slots?

Yes, the kit uses the 288-pin DDR5 RDIMM form factor required by the H13SSH-E; it is not a UDIMM or SODIMM and matches the board's population rules.
