Supermicro H13DSH memory upgrade

This 16 GB DDR5 module is built as an exact-match upgrade for the Supermicro H13DSH motherboard. It delivers registered ECC memory in the 288-pin RDIMM form factor that the board requires. The module targets server administrators who need to expand capacity with a single validated DIMM.

Registered ECC RDIMM with 1Rx8 organisation

The single specification that decides fitment is the registered ECC RDIMM design with 1Rx8 organisation at 1.10 V. This matches the memory controller expectations for rank, voltage and timing so the system recognises the full capacity at the rated DDR5 6400 speed. Builders needing unbuffered UDIMMs or a different rank structure cannot use this part.

Sustained operation with error correction

Under continuous load the registered architecture buffers address and command signals, reducing electrical stress on the memory controller when all slots are populated. On-die ECC corrects single-bit errors in real time, preventing silent data corruption that would otherwise cause unplanned reboots during long-running workloads.

Questions about this item

Will the rated 6400 MT/s speed actually run on a Supermicro H13DSH without manual tuning?

The module is an exact-match upgrade for the H13DSH, so the memory controller recognises the 1Rx8 registered ECC profile at 1.10 V and CL52, allowing it to operate at the full DDR5 6400 (PC5-51200) data rate without extra configuration.

Does the 288-pin RDIMM form factor limit which memory slots I can populate on the H13DSH?

The board requires 288-pin registered RDIMMs — not UDIMMs or SODIMMs — and its population rules dictate the supported capacities and slot order; consult the motherboard manual for the approved sequence before installing.

What physical clearance does this module need inside a 1U or 2U chassis?

The stick uses a standard 288-pin RDIMM height with no heat spreader, so it fits the typical low-profile DIMM sockets found in 1U and 2U server chassis without interfering with airflow shrouds or CPU coolers.
