512GB DDR5 RDIMM kit for Supermicro H13SST-GC

This 512GB kit contains eight 64GB DDR5-4800 registered ECC modules built to the exact rank, voltage and timing the Supermicro H13SST-GC memory controller expects. Each 288-pin RDIMM runs at 1.1V with CL40 latency and a 2Rx4 organisation. The registered architecture is required by this motherboard and will not work in systems that accept only unbuffered UDIMMs or SODIMMs.

Sustained load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller so all eight slots can operate at the rated 4800 MT/s continuously without throttling. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during long compute runs. The 1.1V operating voltage keeps power draw predictable across fully populated channels.

Build quality and daily implications

Modules use major OEM DRAM from Samsung, Micron or Hynix without heat spreaders, relying on server chassis airflow for cooling. The 288-pin RDIMM form factor locks securely into the H13SST-GC DIMM slots in the population order specified by the board manual. Buyers who need a different capacity per module, a UDIMM form factor, or non-ECC memory cannot use this kit.

Questions about this item

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

Each module operates at 1.10V; total system draw depends on the Supermicro H13SST-GC motherboard's memory controller and the workload applied.

What must the motherboard provide for this 8-module kit to be recognised at full 512GB capacity?

The Supermicro H13SST-GC must support 288-pin DDR5 RDIMMs, Registered ECC operation, 2Rx4 organisation and the full eight-slot population per its manual.

Will the CL40 registered ECC modules work with existing DDR5 RDIMMs of different speed or rank?

Mixing is possible only if the board's memory population rules allow it; the kit runs at DDR5-4800 CL40 2Rx4, so any other DIMMs must match voltage and registered ECC type.
