256GB DDR5 ECC RDIMM Kit for Supermicro H13DSG-O-CPU

This 256GB kit contains four 64GB DDR5 5600 registered ECC modules built to the exact voltage, rank and timing the Supermicro H13DSG-O-CPU motherboard expects. It installs as a matched set so the server recognises the full capacity at rated speed.

Who this suits and who should look elsewhere

Suits administrators upgrading a Supermicro H13DSG-O-CPU platform that requires 288-pin registered DDR5 with ECC. Not suitable for systems that accept only unbuffered UDIMMs, SODIMM form factors, or a different DDR generation.

Registered ECC architecture with 2Rx4 organisation

The 2Rx4 registered ECC design offloads the memory controller and corrects single-bit errors, allowing all four slots to run fully populated at 5600 MT/s without data corruption.

Questions about this item

Will the 256GB kit run at DDR5 5600 with CL46 when all four slots of the Supermicro H13DSG-O-CPU are populated?

The kit is spec-matched to the motherboard's memory-population rules so the registered 2Rx4 modules operate at DDR5 5600 (PC5-44800) with CL46 at 1.1V when fully populated.

How much heat and power should I expect from the four 64GB RDIMMs running continuously in a server chassis?

Each module draws 1.1V with no heat spreader; the registered architecture offloads the memory controller, keeping thermals and power draw low enough for dense 24/7 server operation.

Does the Supermicro H13DSG-O-CPU require any specific BIOS setting or firmware version to recognise the full 256GB capacity?

The kit is an exact-match upgrade verified for the H13DSG-O-CPU; follow the board manual for supported capacities, approved DIMM population order and installation steps before purchase.
