System-specific DDR5 server memory

This 128GB NEMIX RAM kit is built for the Supermicro H13DSH motherboard. It targets administrators who need registered ECC modules that the board's memory controller will recognise at full capacity and rated speed.

Installation and common issues

The 288-pin RDIMM form factor matches the board's slots; UDIMM or SODIMM modules will not fit. Follow the motherboard manual for the approved population order so every slot runs fully populated at full capacity.

Rank and voltage compliance

The 2Rx4 organisation at 1.1V with CL40 timing is the exact combination the controller expects; a different rank structure or voltage will prevent the system from posting or running at DDR5 4800.

Questions about this item

How can I confirm the kit is running at DDR5 4800 with CL40 after installation?

Enter the server BIOS or use a hardware-monitoring tool to verify the memory speed reads 4800 MT/s and the CAS latency shows 40; the registered ECC design ensures the controller recognises the 2Rx4 rank at its rated timing.

What ships in the package and do I need any extra parts?

The box contains the 128 GB DDR5 4800 PC5-38400 2Rx4 1.1 V CL40 288-pin ECC RDIMM kit; no additional components are required for a compatible Supermicro H13DSH motherboard.

Which capacity and rank should I select for a fully populated H13DSH?

This 128 GB 2Rx4 registered ECC module matches the board's DDR5 4800 specification; consult the motherboard manual for approved population order and maximum supported capacity per slot.
