System-specific DDR5 kit for Supermicro H13SST-G

This 64 GB kit contains two 32 GB DDR5 RDIMMs built to the exact specifications required by the Supermicro H13SST-G motherboard. It targets administrators upgrading that specific server platform with registered ECC memory that matches the board's population rules.

5600 MT/s CL46 1.1 V registered ECC 2Rx8

The decisive specification is the DDR5-5600 (PC5-44800) speed combined with CL46 latency, 1.10 V operation, and 2Rx8 registered ECC organisation. These parameters must align with the memory controller expectations for the system to recognise the full capacity at rated speed.

Keyed 288-pin RDIMM slots prevent mis-insertion

Installation follows the motherboard manual's DIMM population order; the 288-pin registered form factor only fits RDIMM slots, not UDIMM or SODIMM sockets. The common error is populating slots in the wrong sequence, which can leave the kit undetected or running at reduced speed.

Questions about this item

What does the 5600 MT/s rating actually deliver in a Supermicro H13SST-G server?

The kit runs at DDR5-5600 (PC5-44800) with CL46 latency at 1.1 V, so the memory controller sees the exact speed and timing it expects for full-capacity operation.

How does the registered ECC RDIMM interface affect usable capacity on this board?

Registered buffering offloads the memory controller, allowing both 32 GB modules to be fully populated at rated speed while ECC corrects single-bit errors on the fly.

Will these 288-pin modules fit the DIMM slots on my H13SST-G motherboard?

Yes — the 288-pin RDIMM form factor matches the board's required slot type; it is not a UDIMM or SODIMM and follows the board's population rules.
