Exact-match DDR5-5600 kit

This 128GB kit comprises two 64GB DDR5-5600 (PC5-44800) RDIMMs with CL46 timings at 1.1V. Each module uses a 2Rx4 registered ECC layout on a 288-pin form factor. It is built as a direct upgrade for the Supermicro H14SSL-N motherboard.

Registered ECC changes server behaviour

Registered buffering reduces electrical load on the memory controller so all slots can be populated at full rated speed. On-die ECC detects and corrects single-bit errors in flight, preventing silent data corruption and unplanned reboots in production workloads.

Suits H14SSL-N builds needing maximum capacity

This kit fits administrators expanding a Supermicro H14SSL-N to its supported 128GB ceiling with validated RDIMMs. Buyers who need UDIMM or SODIMM form factors, non-ECC modules, or a different speed grade should look at other listings.

Questions about this item

Will the 2Rx4 registered ECC modules need any firmware updates or periodic re-seating to stay stable in the Supermicro H14SSL-N?

No firmware updates or scheduled re-seating are required; the registered ECC design handles error correction automatically and the modules are validated for continuous operation at DDR5 5600 CL46 1.1V.

What is the first limit reached when the kit runs at full DDR5 5600 speed all day in a fully populated H14SSL-N?

The memory controller’s maximum supported data rate of 5600 MT/s is the first ceiling; the modules are rated for that speed at CL46 and 1.1V, so bandwidth saturates before thermal or power limits.

How much heat and power do the two 64GB RDIMMs produce when the server runs 24/7 at the rated 5600 MT/s?

Each module operates at 1.1V without a heat spreader; registered buffering reduces controller load, so total power draw stays within standard DDR5 RDIMM limits for sustained 5600 MT/s operation.
