Exact-match DDR5 kit for Supermicro H13SSW

This 768GB kit contains eight 96GB DDR5 6400 RDIMMs built to the precise rank, voltage and timing the H13SSW memory controller expects. Registered ECC operation with CL52 latency at 1.1V lets the board recognise full capacity and run at rated speed without manual tuning. It is aimed at administrators expanding memory density on qualified Supermicro platforms.

Eight 288-pin RDIMMs populate every slot the board

Registered buffering offloads the memory controller so all channels remain stable when fully populated, while on-die ECC corrects single-bit errors before they reach the operating system. The modules have no heat spreaders, so airflow across the DIMM rows must follow the chassis design. Verify the motherboard manual for approved population order and maximum supported capacity before installation.

Replaces smaller-capacity or slower DDR5 RDIMM kits

The jump is worth it when workloads need the full 768GB at DDR5-6400 throughput and registered ECC reliability. Systems limited to lower densities, slower speeds or unbuffered DIMMs will not accept this configuration. Buyers who need a different capacity, voltage or form factor should consult their hardware documentation for compatible alternatives.

Questions about this item

Will the 1.10V operating voltage limit stability under sustained full-load server workloads?

The modules run at 1.10V as specified, which is the standard DDR5 RDIMM voltage. Registered buffering and ECC maintain signal integrity across all eight slots at full 768GB capacity.

How much heat do eight 96GB RDIMMs generate when the Supermicro H13SSW runs 24/7?

These modules have no heat spreader. DDR5 moves the PMIC onto each DIMM, so adequate chassis airflow across the 288-pin slots is required to keep temperatures in spec during continuous operation.

Does the Supermicro H13SSW motherboard need a specific BIOS revision or CPU stepping to recognise the full 768GB kit?

The kit is validated for the Supermicro H13SSW. Consult the motherboard manual for the approved DIMM population order, supported capacity per socket, and any BIOS version notes before installation.
