Exact-fit 128GB DDR5 kit for Supermicro H13DSG-OM

This NEMIX RAM kit delivers 128GB across four 32GB DDR5-5600 RDIMMs built to the board's exact specifications. Registered ECC operation with CL46 timing at 1.1V ensures the memory controller recognises full capacity and rated speed. It targets administrators upgrading or populating a Supermicro H13DSG-OM server where registered DIMMs are mandatory. The 2Rx8 organisation matches the platform's population rules for stable, full-slot operation.

Replaces partial or slower DDR5 configurations

A four-module registered kit removes the guesswork of mixing ranks or speeds that can force the controller to down-clock or disable slots. The jump is worth it when your workload needs the full 128GB at the board's native 5600 MT/s without manual tuning. It is not for systems that require unbuffered UDIMMs, SODIMM form factors, or non-ECC memory, as the registered ECC design is electrically and mechanically different.

Check motherboard manual for population order

Verify the approved DIMM slot sequence and maximum supported capacity per processor before ordering, as server boards often restrict which slots fill first at full population. Confirm the BIOS revision on your H13DSG-OM supports the installed density and rank configuration. Ensure the chassis has clearance for standard-height 288-pin RDIMMs without heat spreaders.

Questions about this item

What DIMM slot type does the Supermicro H13DSG-OM require for this 288-pin DDR5 RDIMM kit?

The board requires 288-pin DDR5 RDIMM slots; this kit uses the registered form factor that matches those slots exactly.

In which order should the four 32 GB modules be populated on the H13DSG-OM?

Follow the motherboard manual's DIMM population sequence for four 2Rx8 modules to ensure the memory controller recognises the full 128 GB at DDR5-5600.

Will the 1.1 V operating voltage of these RDIMMs stay within the H13DSG-OM's supported range?

Yes, DDR5 RDIMMs run at 1.1 V by specification, and the H13DSG-OM's memory controller is designed for that voltage.
