Supermicro H13SST-GC DDR5 RDIMM Kit

This 384GB kit contains eight 48GB DDR5 5600 Registered ECC RDIMMs built for the Supermicro H13SST-GC motherboard. The modules run at 1.1V with CL46 latency and a 2Rx8 organisation that matches the board's memory controller expectations. Each stick uses a 288-pin DDR5 form factor and carries Samsung, Micron or Hynix components. The registered architecture lets every slot operate at full population without signal loading issues.

Suits H13SST-GC servers needing maximum registered

Designed for administrators who must populate all eight slots with registered ECC memory on this specific Supermicro platform. Builders requiring unbuffered UDIMMs, SODIMMs, non-ECC modules or lower-density kits should choose a different product. Systems that cannot accept 2Rx8 registered DIMMs at 1.1V will not post with this kit installed.

2Rx8 Registered ECC at 1.1V CL46

The 2Rx8 registered ECC organisation at 1.1V and CL46 is the single specification that decides compatibility with the H13SST-GC memory subsystem. If the motherboard manual calls for a different rank structure, voltage or latency this kit will not operate at its rated 5600 speed. Verify the exact population rules in the system documentation before ordering.

Questions about this item

How do I install the 288-pin RDIMM kit in the Supermicro H13SST-GC and what population step is often missed?

Power down the server, open the chassis, and seat each of the eight 48 GB modules in the exact DIMM order shown in the motherboard manual; the step most often missed is following that specific population sequence so all 384 GB are recognised at 5600 MT/s.

What maintenance or replacement will the registered ECC RDIMMs need during their service life?

The modules have no moving parts and require no scheduled maintenance; if a single-bit error rate ever exceeds what on-die ECC can correct, the affected 48 GB stick is replaced under the lifetime warranty.

What limit appears first when the 1.1 V 2Rx8 kit runs sustained workloads at 5600 MT/s?

The thermal ceiling of the unbuffered DRAM packages without a heat spreader is reached before any electrical timing limit, so adequate chassis airflow must be maintained to keep temperatures in spec.
