256 GB DDR5 ECC RDIMM kit for Supermicro H14DSG-OD

This 256 GB kit contains four 64 GB DDR5 registered DIMMs built for the Supermicro H14DSG-OD motherboard. Each module is a 288-pin RDIMM with ECC and registered buffering. The kit targets server administrators who need the exact capacity and rank configuration their platform requires.

2Rx4 rank and 1.10 V at DDR5-5600 CL46

The memory runs at DDR5 5600 (PC5-44800) with CAS latency 46 at 1.10 volts. The 2Rx4 organisation matches the board’s memory-controller expectations so all four slots operate at the rated speed. Using modules with a different rank structure or voltage would prevent the system from booting at full capacity.

Suits admins populating every slot on a validated

Buyers who need a different total capacity, a UDIMM form factor, or non-ECC memory should look elsewhere. The kit is qualified only for the listed Supermicro platform and its documented population rules.

Questions about this item

What does the 5600MHz speed mean once the kit is installed in a Supermicro H14DSG-OD?

The modules run at the rated DDR5-5600 transfer rate with CL46 latency and 1.1V voltage, so the memory controller recognises the full 256GB capacity at its specified speed without manual tuning.

How does the registered ECC design affect bandwidth and error handling on this board?

Registered buffering reduces electrical load on the memory controller, allowing all four slots to operate at full DDR5-5600 bandwidth, while on-die ECC detects and corrects single-bit errors in real time to prevent silent data corruption.

Will the 288-pin RDIMM form factor and 2Rx4 rank layout fit the H14DSG-OD memory slots?

Yes, the kit uses the exact 288-pin DDR5 RDIMM form factor and 2Rx4 rank organisation the motherboard requires, matching its population rules for a four-module installation.
