Exact-fit DDR5 server kit

This NEMIX RAM kit delivers 768GB of DDR5 memory in sixteen 48GB Registered ECC RDIMM modules. It is built for the Supermicro H13DSG-O-CPU-D motherboard and matches the board's required rank, voltage and timing so the controller recognises the full capacity at the rated speed.

DDR5-4800 population limits

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V using 2Rx8 registered chips. Full-slot population at this speed depends on the motherboard's qualified vendor list and CPU memory-controller capabilities; consult the system manual for the approved DIMM sequence and maximum supported capacity per channel.

Sixteen-module registered ECC capacity

The single specification that decides fitment is the sixteen 48GB 2Rx8 Registered ECC RDIMMs totalling 768GB. Only systems that support this exact module count, rank structure and registered architecture will initialise the kit at its rated DDR5-4800 specification.

Questions about this item

Should I choose the 768GB kit with sixteen 48GB modules or a smaller capacity for my Supermicro H13DSG-O-CPU-D?

The 768GB kit fills all sixteen slots with 48GB RDIMMs, giving the maximum supported density for this motherboard; choose it when your workloads need the full capacity and your CPU supports that population.

What does the DDR5 4800 speed rating mean once the modules are installed in the server?

The memory controller will run the kit at 4800 MT/s with CL40 latency at 1.1 V, delivering the rated PC5-38400 bandwidth across all populated channels.

How does the 288-pin RDIMM interface and registered ECC design affect real-world operation?

The registered buffer reduces electrical load on the memory controller so all sixteen slots operate at full speed, while ECC corrects single-bit errors on the fly to prevent silent data corruption.
