Exact-match DDR5 ECC kit

This NEMIX RAM kit supplies 64 GB of DDR5 4800 registered ECC memory in four 16 GB modules. It is built for the Supermicro H13DSG-OM motherboard where the memory controller expects 1Rx8 registered DIMMs at 1.1 V and CL40 timing. The kit matches the board’s required rank, voltage and latency so the system recognises the full capacity at rated speed.

Installation and common issues

The 288-pin RDIMM form factor seats only in registered DIMM slots; a UDIMM or SODIMM will not fit. Populate the sockets in the order specified by the motherboard manual because registered memory population rules differ from unbuffered layouts. The modules have no heat spreader so airflow across the DIMM rows is required; restricted airflow can cause throttling under sustained load.

Pre-order checks

Confirm the Supermicro H13DSG-OM manual lists 64 GB total capacity with four 16 GB 1Rx8 registered ECC modules at DDR5 4800. Verify the approved DIMM population sequence for a fully populated configuration. Ensure the chassis provides adequate airflow over bare modules and that the power budget accommodates the additional memory.

Questions about this item

How can I confirm the DDR5 4800 RDIMM kit is running at its rated CL40 1.1V speed after installing it in the Supermicro H13DSG-OM?

Enter the BIOS or UEFI on the Supermicro H13DSG-OM and verify the memory information screen shows all four modules detected at 4800 MT/s with CL40 timings and 1.1V.

What is included in the package and do I need any extra parts for installation?

The kit includes four 16GB DDR5 4800 ECC Registered RDIMM modules for a total of 64GB. No additional components are required for installation on the H13DSG-OM.

Which capacity kit should I choose if my H13DSG-OM manual lists 64GB as a supported configuration?

Select this 64GB kit (4 x 16GB) because it matches the exact capacity, rank (1Rx8), voltage (1.1V), and registered ECC RDIMM form factor specified for that configuration.
