Exact-match DDR5 kit for Supermicro H13DSH

This 128GB kit delivers two 64GB Registered ECC DDR5 modules rated at 5600MHz with CL46 latency and 1.1V operation. It is built for administrators upgrading a Supermicro H13DSH motherboard who need the precise rank, voltage, and timing the memory controller expects. The modules install as a matched pair to run at full rated capacity and speed.

Registered RDIMM form factor with ECC integrity

Each module uses the 288-pin RDIMM form factor required by the H13DSH, not UDIMM or SODIMM, so it seats correctly in the server's DIMM slots. The registered architecture buffers the memory bus, allowing full population without signal degradation, while on-die ECC corrects single-bit errors before they reach the operating system. No heat spreaders are fitted, relying on chassis airflow for cooling.

Verify population rules and supported capacity

Before ordering, consult the Supermicro H13DSH manual for approved DIMM population order, maximum supported capacity per channel, and any BIOS version requirements. Server memory validation lists vary by board revision, and incorrect slot placement can prevent boot or limit performance. Confirm your configuration matches the 2Rx4 registered specification.

Questions about this item

Does the DDR5 5600 interface run at 44800 MT/s with CL46 latency?

Yes, the kit is rated DDR5 5600 (PC5-44800) with a CAS latency of CL46, so the memory controller will operate at 44800 MT/s at that timing.

Will the 288-pin RDIMM modules fit the Supermicro H13DSH motherboard slots?

The modules use the 288-pin RDIMM form factor required by the H13DSH; they are not UDIMM or SODIMM and match the board's physical slot keying.

How do I install the 2Rx4 registered DIMMs in the correct population order?

Consult the H13DSH manual for the approved DIMM population sequence, install each 64 GB module in the specified slots, and seat them fully until the retention clips lock.
