Capacity and form factor

This is a 384GB kit of six 64GB DDR5 registered ECC RDIMMs built for the Supermicro H13DSG-O-CPU-D motherboard. Each module uses a 288-pin layout and 2Rx4 organisation so the memory controller sees the exact rank structure it expects. The kit is designed for servers that require registered memory to run fully populated at rated speed.

DDR5 registered ECC limits

Registered DIMMs buffer the command and address bus, allowing all slots to be filled without overloading the memory controller, while ECC corrects single-bit errors on the fly. The modules operate at 1.1V with a CL40 latency at the DDR5-4800 data rate. Systems that require unbuffered UDIMMs or SODIMMs cannot use this kit, and boards with stricter population rules may not support a full six-module installation.

Speed grade and rank

The decisive specification is the DDR5-4800 (PC5-38400) speed grade combined with 2Rx4 registered ECC organisation at 1.1V. If your platform demands a different data rate, voltage, rank configuration or unbuffered modules, this kit will not be recognised or will run at a reduced speed. Verify the motherboard's qualified vendor list before purchase.

Questions about this item

Should I choose this 6 x 64 GB kit or a smaller capacity for my Supermicro H13DSG-O-CPU-D?

This 384 GB kit fills six DIMM slots with 64 GB modules, matching the board's DDR5-4800 registered ECC requirements; select it when you need the full capacity the platform allows.

What does DDR5-4800 (PC5-38400) deliver once the modules are installed in the server?

The memory runs at 4800 MT/s with CL40 latency at 1.10 V, providing the rated bandwidth and error-correcting stability the motherboard's memory controller expects.

How does the 288-pin RDIMM interface limit speed or capacity in practice?

The registered 288-pin DDR5 form factor supports the full 4800 MT/s data rate and 64 GB per module, enabling all six slots to operate at rated speed without downclocking.
