Exact-match DDR5 kit for Supermicro H13SST-G

This 768GB kit contains twelve 64GB DDR5 4800 CL40 registered ECC RDIMMs built to the voltage and rank layout the H13SST-G memory controller expects. It is intended for administrators who need the full 768GB capacity on that specific motherboard.

Verify DIMM population rules in the board manual

The H13SST-G requires 288-pin RDIMMs and enforces a specific slot-filling order that varies with CPU count and BIOS revision. Check the manual for supported capacities per channel and the approved installation sequence before you open the package.

Registered design runs at 1.1V

The buffered architecture reduces electrical load on the memory controller when all twelve slots are populated, while ECC corrects single-bit errors on the fly. Modules operate at the standard 1.10V DDR5 voltage and rely on server chassis airflow for cooling.

Questions about this item

Does the 768GB kit ship as twelve individual 64GB modules or must extra DIMMs be purchased?

The package contains twelve 64GB DDR5 4800 CL40 1.1V ECC Registered RDIMM modules, delivering the full 768GB capacity in a single kit.

Should I pick the 12x64GB 2Rx4 configuration or a different capacity for the Supermicro H13SST-G?

Choose this 12x64GB 2Rx4 kit when the motherboard manual calls for fully populated registered ECC DIMMs at DDR5-4800; other capacities or ranks may not match the board's population rules.

Will the DDR5-4800 CL40 rating hold at 768GB in a live Supermicro H13SST-G server?

Yes — the kit is spec-matched to the H13SST-G memory controller so all twelve registered ECC modules run at the rated 4800 MT/s with CL40 latency when installed per the board's population guide.
