64GB DDR5 ECC RDIMM kit for Supermicro H13SST-G

This 64GB kit contains two 32GB DDR5-4800 registered ECC modules built to the exact rank, voltage and timing the Supermicro H13SST-G memory controller expects. It targets server administrators who need guaranteed recognition at full capacity and rated speed without manual tuning.

DDR5-4800 registered ECC limits

The modules run at DDR5-4800 (PC5-38400) with CL40 latency at 1.10V using a 2Rx8 organisation. Registered buffering lets every slot run fully populated at full capacity, while ECC corrects single-bit errors on the fly. The 288-pin RDIMM form factor is mandatory; UDIMM or SODIMM modules will not fit or function on this board.

Installation and common issues

Insert the DIMMs in the population order specified by the Supermicro H13SST-G manual to enable all 64GB at DDR5-4800. The most frequent problem is ignoring the board's slot sequence, which causes reduced capacity or fallback speeds. Verify the approved configuration before purchase and follow the documented installation steps.

Questions about this item

Should I choose the 64GB kit with two 32GB modules or a different capacity for my Supermicro H13SST-G?

This kit provides exactly 64GB using two 32GB Registered ECC RDIMMs, matching the motherboard's DDR5 slot requirements and population rules for full-capacity operation.

What does the DDR5-4800 speed rating mean once the modules are installed in the server?

The memory controller will run the kit at 4800 MT/s with CL40 latency at 1.1V, delivering the rated PC5-38400 bandwidth when the board is fully populated with these 2Rx8 Registered DIMMs.

How does the 288-pin RDIMM interface and Registered ECC design affect real-world use?

The 288-pin Registered form factor is required by the H13SST-G; registration buffers the address bus so every slot runs stably at full capacity, while ECC corrects single-bit errors to prevent silent data corruption.
