Capacity and fit

This kit provides 384GB of DDR5 memory across twelve 32GB RDIMM modules. It is built for the Supermicro H13DSG-O-CPU-D motherboard and matches the exact rank, voltage and timing that the board's memory controller expects.

Registered ECC architecture

Each module is a 288-pin DDR5-4800 RDIMM running at 1.1V with CL40 latency and 2Rx8 organisation. Registered buffering and on-die ECC let all twelve slots run fully populated at rated speed while correcting single-bit errors.

Suited for full-population server builds

The kit targets administrators who need the maximum supported capacity on this specific Supermicro platform. Buyers using a different motherboard, or who need UDIMM or SODIMM form factors, should look elsewhere.

Questions about this item

What does DDR5-4800 mean for actual throughput in a Supermicro H13DSG-O-CPU-D server?

DDR5-4800 (PC5-38400) sets the data rate the memory controller expects; with twelve 2Rx8 registered modules installed, the board can address the full 384 GB kit at that rated speed.

How does the 288-pin RDIMM interface limit installation on this motherboard?

The H13DSG-O-CPU-D requires 288-pin Registered DIMMs; UDIMMs or SODIMMs will not fit the slots, and the board's population rules dictate which of the twelve modules go in first.

What physical clearance does this 12-module kit need inside a 2U chassis?

Each 32 GB stick is a standard-height 288-pin RDIMM without a heat spreader, so the kit fits the regular DIMM spacing defined by the Supermicro H13DSG-O-CPU-D layout.
