Exact-match DDR5-4800 kit for Supermicro H13DSH

This 64 GB kit delivers two 32 GB registered ECC DDR5 RDIMMs built to the 288-pin DDR5-4800 (PC5-38400) standard at 1.1 V and CL40. It targets administrators upgrading a Supermicro H13DSH motherboard that requires registered memory with ECC.

Registered ECC RDIMM form factor

The single specification that determines fit is the registered ECC RDIMM design; the motherboard's memory controller expects buffered modules with on-die error correction and will not accept unbuffered UDIMMs or SODIMMs.

Dual-rank 2Rx8 organisation at full speed

Each module uses a 2Rx8 layout so the controller can address the full 64 GB across both slots at the rated 4800 MT/s. Capacity heads up at 64 GB; larger configurations would require additional DIMM slots and motherboard support not covered by this kit.

Questions about this item

Will the DDR5-4800 speed run at its rated 4800 MHz once installed in a Supermicro H13DSH?

Yes, the kit is spec-matched to the H13DSH memory controller so it is recognised at full capacity and operates at its rated DDR5-4800 speed without manual tuning.

What does the registered ECC RDIMM interface do for a fully populated server?

Registered buffering offloads the memory controller, allowing every slot to run fully populated at full capacity, while ECC corrects single-bit errors on the fly to prevent silent data corruption.

What physical slot and form factor does this 288-pin kit require on the motherboard?

It requires standard 288-pin DDR5 RDIMM slots; the modules have no heat spreader and fit the H13DSH's registered DIMM sockets directly.
