Exact-match 384GB DDR5 kit

This 384GB kit contains twelve 32GB DDR5-4800 registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13DSG-O-CPU motherboard expects. It is intended for administrators who need to populate every slot at full rated capacity without manual tuning.

Registered 288-pin RDIMM form factor

Each module uses the 288-pin registered RDIMM layout this board requires, not UDIMM or SODIMM, and operates at 1.1V with CL40 latency. The registered architecture buffers address and command signals so all twelve slots remain stable when fully populated, while on-die ECC corrects single-bit errors before they affect production workloads.

DDR5-4800 bandwidth ceiling

The PC5-38400 interface caps peak transfer rate at the DDR5-4800 specification, so throughput cannot exceed that limit regardless of CPU capability. Population rules and maximum supported capacity vary by motherboard revision, so the system manual must be consulted before installation to confirm supported configurations.

Questions about this item

Does this DDR5 4800 kit run at PC5-38400 speed on the Supermicro H13DSG-O-CPU?

The modules are rated DDR5 4800 (PC5-38400) with CL40 latency and 1.1 V operation, matching the board's supported memory standard.

Will these 288-pin RDIMMs physically fit the Supermicro H13DSG-O-CPU memory slots?

The kit uses 288-pin registered RDIMM form factor, which is the exact module type the H13DSG-O-CPU motherboard requires.

What is the correct population order for all 12 modules on this motherboard?

Install the DIMMs following the population sequence shown in the Supermicro H13DSG-O-CPU manual; the board's memory-controller topology dictates the slot order for full 12-module operation.
