Supermicro H14DSH 128GB DDR5 Kit

This NEMIX RAM kit delivers a single 128GB DDR5 4800 RDIMM built to the exact rank, voltage and timing the Supermicro H14DSH motherboard expects. Registered ECC architecture lets every slot run fully populated while correcting single-bit errors on the fly. The module operates at 1.1V with CL40 latency and uses a 2Rx4 organisation for maximum density.

Administrators needing maximum capacity per slot

Server operators who want the highest supported capacity in each DIMM slot will match the board's population rules with this 128GB part. Builders using unbuffered UDIMM or SODIMM form factors cannot install this registered RDIMM on their platforms.

2Rx4 Registered ECC at 4800 MT/s

The 2Rx4 registered ECC organisation running at DDR5 4800 is the specification that decides fitment. Only motherboards wired for registered DDR5 RDIMMs with this rank structure and speed will recognise the full 128GB at rated performance.

Questions about this item

What motherboard slot type must my Supermicro H14DSH have free to install this 288-pin RDIMM?

The board needs an empty 288-pin DDR5 RDIMM slot; the kit is a registered DIMM and will not fit UDIMM or SODIMM sockets.

Can I mix this 128GB 2Rx4 module with existing 1Rx8 DDR5 RDIMMs in the same H14DSH?

Mixing ranks is possible if the motherboard manual allows it; populate slots in the order the manual specifies and the memory controller will negotiate a common speed.

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

Check BIOS or an OS tool such as dmidecode — it should report 4800 MT/s, CAS latency 40, 1.10 V and the full 128 GB capacity per module.
