Server Memory Kit for Supermicro H13SST-G

This 384GB kit contains twelve 32GB DDR5 RDIMM modules built to the exact specifications of the Supermicro H13SST-G motherboard. It delivers registered ECC memory at 6400MHz with CL52 latency and 1.10V operation for enterprise server workloads.

Installation Notes

The 288-pin RDIMM form factor fits the motherboard's registered DIMM slots directly. Full population across all twelve slots requires following the board's specific population order in the manual; incorrect sequencing or mixing with unbuffered UDIMMs will prevent the system from booting or recognising the full capacity.

Critical Specification: Registered ECC DDR5-6400

The motherboard requires registered (buffered) ECC DDR5 RDIMMs at this speed and voltage. This kit matches that requirement precisely. It is not for systems needing unbuffered UDIMMs, SODIMMs, non-ECC memory, or a different DDR generation or data rate.

Questions about this item

How can I verify the kit is running at DDR5 6400 CL52 1.1V on the Supermicro H13SST-G after installation?

Enter the BIOS or use a tool such as dmidecode to confirm each of the 12 modules shows 32 GB, 6400 MT/s, CL52 latency and 1.1 V operation with ECC active.

What exactly ships in the box and is anything else required to complete the upgrade?

The box contains the 12-piece 288-pin RDIMM kit totalling 384 GB; no extra parts are needed if the board has 12 free DDR5 RDIMM slots.

Should I choose this 12 x 32 GB kit or a different capacity for the H13SST-G?

Pick this kit when you need the full 384 GB across all 12 channels; select a smaller kit only if your workload fits in less memory and the manual approves partial population.
