64 GB DDR5 ECC RDIMM kit for Supermicro

This NEMIX RAM kit delivers 64 GB of DDR5 4800 registered ECC memory in a 4 x 16 GB configuration. It matches the Supermicro H13DSG-O-CPU-D motherboard's required 288-pin RDIMM form factor, 1.1 V voltage and CL40 timing. The modules use 1Rx8 organisation with major OEM chips for enterprise stability.

Who this suits and who should look elsewhere

Server administrators upgrading or populating a Supermicro H13DSG-O-CPU-D system with the exact registered ECC specification the board expects. Builders needing unbuffered UDIMM or SODIMM modules cannot use this kit. Systems requiring different speeds, voltages or capacities must select a validated alternative.

DDR5 4800 registered ECC with 1Rx8 organisation

The DDR5 4800 (PC5-38400) registered ECC design with 1Rx8 rank organisation is the decisive specification. It ensures the memory controller recognises every module at full capacity and rated speed while ECC corrects single-bit errors on the fly. Verify your motherboard manual for supported population rules before purchase.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Supermicro H13DSG-O-CPU-D motherboard slots?

Yes, the kit uses the 288-pin Registered RDIMM form factor that the H13DSG-O-CPU-D requires; it is not a UDIMM or SODIMM and matches the board's physical slot keying.

What is the correct installation order for the four 16 GB modules on this board?

Populate all four slots following the motherboard manual's DIMM population sequence for a 4-module configuration; the kit is spec-matched to those population rules.

Do the modules need active cooling or heat-spreader maintenance over time?

No heat spreader is fitted and none is required; the 1.10 V DDR5 modules run within standard thermal limits, so only occasional dust removal from the server chassis is needed.
