  • 288-pin 2Rx8 form factor verified for Supermicro H13SSH motherboard

Server-grade DDR5 upgrade for Supermicro H13SSH

This 64GB kit uses two 32GB registered ECC RDIMMs built to the exact DDR5 5600 specification the board requires. It targets administrators who need to populate every slot at full capacity without timing mismatches or voltage drift.

Registered ECC RDIMM with 2Rx8 organisation

The modules run at 1.1V with CL46 latency and a 2Rx8 rank structure that matches the motherboard's memory-controller expectations. Unbuffered UDIMMs or SODIMMs will not work in this platform, so the registered form factor is the single decisive specification.

Kit contains only the two memory modules

No heat spreaders, cables, software licences or mounting hardware are included. The package delivers the verified 288-pin DDR5 RDIMMs so you can install them directly according to the board's population rules.

Questions about this item

What does the DDR5 5600 rating mean for actual throughput on my Supermicro H13SSH?

The modules run at 5600 MT/s, delivering PC5-44800 bandwidth when the board's memory controller is fully populated with registered DIMMs.

How does the 288-pin RDIMM interface limit or enable my memory configuration?

The 288-pin registered form factor is required by the H13SSH; it allows all slots to be filled at 64 GB total while the buffer offloads the memory controller.

Will these 32 GB dual-rank sticks physically fit the H13SSH DIMM slots without a heat spreader?

Yes, the 288-pin RDIMM modules are the exact height and keying the board expects, and the lack of a heat spreader poses no clearance issue.
