Exact-Match DDR5 Kit

This 512 GB kit contains eight 64 GB DDR5 RDIMMs rated at 4800 MT/s with CL40 latency and 1.1 V operation. Each module uses a 2Rx4 registered ECC design that matches the Supermicro H13DSG-OM memory controller requirements. The 288-pin form factor fits the server board's DIMM slots without adapters or workarounds.

Sustained Load Behaviour

Registered buffering reduces electrical load on the memory controller so all eight slots can run fully populated at the rated 4800 MT/s speed. ECC circuitry detects and corrects single-bit errors during continuous operation, preventing silent data corruption that would otherwise accumulate under heavy throughput. The 2Rx4 organisation maintains consistent bandwidth across long-running compute or virtualization workloads.

Thermals and Power

Modules operate at the standard DDR5 voltage of 1.10 V and ship without heat spreaders, relying on server chassis airflow for cooling. Registered architecture lowers per-pin current draw compared with unbuffered alternatives, reducing total power consumption when the kit is fully installed. Silent passive operation suits rack environments where acoustic limits are strict.

Questions about this item

How much power does the 1.10V DDR5 4800 kit draw when the server runs all day?

Each module operates at 1.10V, the standard DDR5 voltage, so total draw depends on how many of the eight 64GB sticks your board populates and the CPU memory controller load.

What must the motherboard provide for this 288-pin RDIMM kit to function?

The board needs eight DDR5 RDIMM slots that support registered ECC memory, 2Rx4 organisation, CL40 timing at 4800 MT/s and the Supermicro H13DSG-OM memory-population rules.

Can I mix these 64GB 2Rx4 modules with smaller DDR5 RDIMMs already in the system?

Mixing ranks or capacities is only safe if the motherboard manual explicitly approves the population order; otherwise the memory controller may downclock or fail to train.
