Supermicro H13SST-G DDR5 RDIMM upgrade

This 16 GB DDR5-6400 registered ECC module is built to the exact rank, voltage and timing the Supermicro H13SST-G motherboard expects. It installs as a 288-pin RDIMM and runs at PC5-51200 speed with CL52 latency at 1.10 V. The registered design lets every supported slot run fully populated at rated capacity while ECC corrects single-bit errors on the fly.

Suits servers needing registered ECC.

This module fits Supermicro H13SST-G systems that require registered DDR5 RDIMMs with ECC. Builders whose boards accept only unbuffered UDIMMs or laptop-style SODIMMs cannot use it. The single-rank 1Rx8 organisation matches the board's population rules, so it works in configurations that demand that specific layout.

Registered DDR5 ECC RDIMM at 6400 MT/s

The decisive spec is the registered DDR5 ECC RDIMM interface running at 6400 MT/s with CL52 timing at 1.10 V. Only motherboards wired for 288-pin registered DDR5 ECC modules can accept this part; UDIMM-only or SODIMM-only platforms will not recognise it. Verify your system manual for approved capacities and slot population order before purchase.

Questions about this item

Will this 16 GB DDR5 6400 RDIMM work in my Supermicro H13SST-G motherboard?

Yes, it is spec-matched for the H13SST-G. The board requires 288-pin Registered DDR5 ECC modules; this kit meets the exact rank, voltage, and timing the memory controller expects.

Can I mix this 1Rx8 CL52 module with existing DDR5 RDIMMs of different rank or speed?

Mixing ranks or speeds forces the controller to run all slots at the lowest common settings. For full 6400 MT/s performance and stability, populate remaining slots with identical 1Rx8 CL52 1.10 V modules.

How do I confirm the module is running at 6400 MT/s with ECC active after installation?

Enter the BIOS or use a tool like dmidecode on Linux. Verify the reported speed shows 6400 MT/s (PC5-51200), the voltage reads 1.10 V, and ECC status is reported as enabled or active.
