Exact-fit DDR5 server kit

This 384 GB kit contains twelve 32 GB DDR5-5600 registered ECC RDIMMs built to the precise 2Rx8 rank, 1.10 V voltage and CL46 timing the Supermicro H13SSH-E memory controller expects. It is intended for administrators who must populate every slot at full rated speed without manual tuning.

Thermals and power profile

Operating at the standard DDR5 1.10 V, the modules draw minimal power per DIMM even when all twelve slots are filled. No heat spreaders are fitted, so airflow across the bare PCBs handles the thermal load in a properly ventilated server chassis. Registered buffering reduces electrical loading on the memory controller, keeping signal integrity stable under sustained workloads.

Build integration

The 288-pin RDIMM form factor matches the board's registered DIMM slots exclusively; UDIMM or SODIMM modules will not fit. ECC corrects single-bit errors on the fly, while registered architecture lets the platform run fully populated at the rated 5600 MT/s. Verify the motherboard manual for approved population order and maximum supported capacity before installation.

Questions about this item

How do I install the 12 DDR5 RDIMM modules on the Supermicro H13SSH-E motherboard, and which population step is often missed?

Follow the motherboard manual for the approved DIMM population order; the step often missed is populating slots in the exact sequence required for 12 modules so the memory controller recognises all 384GB at DDR5-5600.

What maintenance or replacement will this 2Rx8 registered ECC kit need over its service life?

The modules have no moving parts and no heat spreader; maintenance is limited to keeping server airflow clean, and replacement occurs only if a module fails, covered by the lifetime replacement warranty.

What is the first limit that appears under sustained full-capacity load with all 12 slots populated?

The registered buffer and 1.10V operation keep every slot stable at CL46 5600MT/s, so the first limit is the motherboard's maximum supported capacity and population rules, not the memory itself.
