System-specific DDR5 server memory kit

This 64 GB kit contains four 16 GB DDR5-5600 registered ECC RDIMMs built for the Supermicro H13SST-GC motherboard. The modules run at 1.1 V with a CL46 latency and a 1Rx8 rank layout that matches the board's memory controller requirements. They install in the 288-pin DIMM slots and are recognised at full capacity without manual configuration.

Registered ECC architecture for full-slot stability

Registered buffering offloads the memory controller so all four slots can be populated at the rated 5600 MT/s speed. On-die ECC detects and corrects single-bit errors in flight, preventing silent data corruption that would otherwise crash production workloads. The 1Rx8 organisation is the exact rank structure the H13SST-GC expects for this capacity.

Kit-only packaging with no heat spreaders

The package delivers the four matched RDIMMs and nothing else; there are no heat spreaders, cables, software licences or documentation discs included. Builders must consult the motherboard manual for the approved population order and any BIOS settings before installation. Buyers who need thermal management accessories or a smaller two-module kit will have to source those separately.

Questions about this item

What does DDR5-5600 mean once the kit is installed in a Supermicro H13SST-GC server?

The modules will run at 5600 MT/s, delivering PC5-44800 bandwidth per DIMM when the memory controller is set to its rated speed.

How does the registered ECC interface affect usable capacity and speed on this board?

Registered buffering lets all four slots run fully populated at 5600 MT/s, while ECC corrects single-bit errors on the fly without reducing the 64 GB total.

What physical slot and clearance does the 288-pin RDIMM kit need in the H13SST-GC?

Each 16 GB module fits a standard 288-pin DDR5 RDIMM slot; the kit has no heat spreader, so it clears typical server heatsinks and airflow ducts.
