  • DDR5 4800 speed with CL40 timing matches the board's rated frequency exactly
  • Registered ECC architecture corrects single-bit errors and buffers every slot fully populated
  • 10 V operation at 2Rx4 rank aligns with the memory controller's native spec
  • 288-pin RDIMM form factor verified for Supermicro H13SST-GC motherboard compatibility

Exact-Match Server Kit

This 768 GB kit contains six 128 GB DDR5 4800 RDIMMs built for the Supermicro H13SST-GC motherboard. Registered ECC modules with 2Rx4 organisation and CL40 timing deliver the precise rank, voltage and latency the platform expects. The memory controller recognises every slot at full capacity without manual tuning.

Sustained Load Stability

Registered architecture buffers each command so the memory controller stays stable when all six slots run fully populated at 4800 MT/s. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. Operation at 1.1 V keeps power draw predictable across extended workloads.

Installation Notes

Align the 288-pin RDIMM key with the motherboard slot and press evenly until the latches click. Follow the board manual for the approved population order; skipping a required sequence will leave capacity unrecognised. No heat spreader is fitted, so verify chassis airflow before deploying in dense configurations.

Questions about this item

How much power does the 1.1V DDR5-4800 768GB kit draw when the server runs continuously?

Each 128GB module operates at 1.10V; total system power depends on the Supermicro H13SST-GC memory controller and workload, not the kit alone.

What motherboard slot type must the Supermicro H13SST-GC provide for these 288-pin RDIMMs?

The board needs six DDR5 288-pin RDIMM slots that support registered ECC memory population rules.

Will the 2Rx4 registered ECC DDR5 modules work in the same channels as other DDR5 RDIMMs already installed in the H13SST-GC?

Mixing ranks or capacities can change population rules; consult the motherboard manual for approved DIMM configurations before adding this kit.
