Exact-fit DDR5 RDIMM for Supermicro H13DSG-O-CPU-D

This NEMIX RAM module delivers 32GB of DDR5 4800 registered ECC memory in a 288-pin RDIMM form factor. It operates at 1.1V with CL40 latency and a 2Rx8 rank structure. The part number MR38400-328K1 identifies the exact specification your server's memory controller expects.

Verify motherboard population rules before ordering

Check the Supermicro H13DSG-O-CPU-D manual for supported capacities per slot and the required DIMM installation sequence. Registered ECC RDIMMs are not interchangeable with unbuffered UDIMMs or SODIMMs, so confirm the board calls for registered modules. Ensure all slots follow the approved population order for full-speed operation.

Suited for admins expanding validated Supermicro

This kit fits administrators adding capacity to a verified H13DSG-O-CPU-D platform where registered ECC memory is mandatory. It is not for builders using consumer motherboards that accept only unbuffered UDIMMs. Buyers needing non-ECC modules, different voltages, or laptop SODIMM form factors should look elsewhere.

Questions about this item

What comes in the box and is anything else needed to install this 32GB DDR5 4800MHz ECC RDIMM?

The package contains one 32GB DDR5 4800MHz PC5-38400 2Rx8 1.1V CL40 288-pin ECC Registered RDIMM. No extra parts are required; the module plugs directly into a compatible 288-pin RDIMM slot on the Supermicro H13DSG-O-CPU-D motherboard.

Should I choose the 2Rx8 registered ECC version or a different rank or voltage for this board?

This 2Rx8 1.1V CL40 registered ECC module matches the exact rank, voltage and timing the Supermicro H13DSG-O-CPU-D memory controller expects. Using a different rank, voltage or unbuffered DIMM would prevent full-capacity recognition or rated-speed operation.

What does the 4800MHz PC5-38400 rating mean once the RDIMM is installed in the server?

The module will run at DDR5 4800 MT/s (PC5-38400 bandwidth) with CL40 latency at 1.1V, delivering the full rated throughput and error-correcting stability the motherboard's memory controller is designed for when populated per the manual's slot order.
