512GB DDR5 5600 ECC RDIMM Kit

This 512GB kit contains sixteen 32GB DDR5 5600 registered ECC RDIMMs built for the Supermicro H14DSH motherboard. The 2Rx8 organisation, 1.1V operating voltage and CL46 latency match the board's memory controller requirements exactly. System integrators populating every slot receive the full rated capacity at the rated speed without manual tuning.

Sustained Load Behaviour

Registered buffering reduces electrical load on the memory controller so all sixteen modules operate together at DDR5 5600 continuously. ECC circuitry detects and corrects single-bit errors in real time, preventing silent data corruption during long-running compute or database workloads. The 1.1V supply keeps power draw stable across fully populated channels under extended duty cycles.

DDR5 Interface Limits

DDR5 5600 (PC5-44800) sets the maximum data rate this kit can deliver on the 288-pin RDIMM interface. Population rules in the H14DSH manual determine how many of the sixteen modules can be active simultaneously and in which slot order. Exceeding the board's qualified capacity or ignoring the approved population sequence will prevent the system from reaching the rated 5600 MT/s transfer rate.

Questions about this item

Does the 1.10 V registered design keep heat and power draw manageable when all 16 modules run continuously?

The kit operates at 1.10 V with registered buffering, which reduces electrical load on the memory controller and helps maintain stable thermals during sustained full-capacity operation.

What motherboard and slot configuration are required to install this 16 x 32 GB kit?

A Supermicro H14DSH motherboard with 16 available 288-pin DDR5 RDIMM slots, populated according to the board's memory population rules, is required.

Can the 2Rx8 registered ECC modules work in a mixed population with other DDR5 RDIMMs already in the system?

Mixing ranks, voltages or timings is not recommended; the board's memory controller expects identical 2Rx8 CL46 1.10 V modules in every populated slot for reliable operation at DDR5 5600.
