Capacity and purpose

This 512GB kit contains four 128GB DDR5 modules built for the Supermicro H13DSH motherboard. It targets servers that require maximum registered ECC capacity in every slot.

Registered ECC form factor

Each module is a 288-pin RDIMM with a 2Rx4 organisation and no heat spreader. The registered design buffers address and command signals so the memory controller remains stable when all channels are fully populated, while ECC corrects single-bit errors before they affect data integrity.

Voltage and timing

The kit operates at 1.1V with a CL46 latency at 5600 MT/s. Running at the standard DDR5 voltage keeps power draw predictable in dense configurations, and the rated timing is the exact value the platform expects for reliable operation.

Questions about this item

Does this DDR5-5600 RDIMM kit run at its rated 5600 MT/s on the Supermicro H13DSH, or does the board cap it lower?

The kit is spec-matched to the H13DSH memory controller, so all four 128 GB modules operate at DDR5-5600 (PC5-44800) with CL46 at 1.1 V when populated per the board's rules.

Will these 288-pin registered DIMMs physically fit the H13DSH slots without clearance issues?

Yes — each module is a standard 288-pin DDR5 RDIMM with no heat spreader, matching the exact form factor the H13DSH DIMM sockets require.

What is the correct population order for all four modules on the H13DSH, and what step do installers often miss?

Follow the motherboard manual's approved DIMM sequence for four 2Rx4 registered modules; the step most often missed is verifying the exact slot order before seating every DIMM.
