Exact-match upgrade for Supermicro H13DSH

This 256GB kit delivers two 128GB DDR5 RDIMMs rated at 5600MHz with CL46 timing and 1.1V operation. Registered ECC architecture meets the server board's population rules so every slot runs at full capacity.

Sustained-load behaviour

Registered buffering offloads the memory controller, allowing all populated channels to maintain rated throughput during extended workloads. ECC corrects single-bit errors on the fly to prevent silent data corruption.

Thermals and power

Modules operate at 1.1V without heat spreaders, relying on chassis airflow for cooling. The low-voltage DDR5 design keeps power draw modest while the registered design reduces electrical load on the motherboard.

Questions about this item

How much power does the 1.10V DDR5 5600 kit draw when the server runs continuously?

Each module operates at 1.10 volts, the standard DDR5 voltage, so total power scales with the 256GB capacity and 5600 MT/s data rate; registered buffering also reduces electrical load on the memory controller.

What must the motherboard provide for these 288-pin registered ECC DIMMs to function?

The board needs DDR5 RDIMM slots that support 2Rx4 registered ECC modules at 5600 MT/s and a memory controller able to address 128GB per DIMM; the Supermicro H13DSH meets those requirements.

Can I mix this 2Rx4 CL46 kit with other DDR5 registered ECC DIMMs already in my H13DSH?

Mixing is possible only if the existing DIMMs are also DDR5 registered ECC with matching 2Rx4 organization, 1.10V voltage and 5600 MT/s speed; otherwise the system will down-clock or fail to boot.
