Exact-fit DDR5 RDIMM kit for Supermicro X14SDV

This NEMIX RAM kit delivers 256 GB as two 128 GB DDR5 5600 RDIMMs built to the Supermicro X14SDV-32C-SP3F motherboard's exact specification. Registered ECC architecture lets every slot run fully populated while correcting single-bit errors on the fly. The modules arrive new and ready for enterprise workloads.

Registered ECC with 4Rx4 rank and CL46 timing

The single specification that decides fit is the 4Rx4 registered ECC layout at 1.1 V with CL46 latency. Your board's memory controller expects this precise rank, voltage and timing combination so the full 256 GB is recognised and runs at its rated DDR5 5600 speed. Any other rank or voltage will not post.

288-pin RDIMM installs in seconds.

Installation is a standard 288-pin RDIMM insertion, but the Supermicro manual defines a strict DIMM population sequence that must be followed or the system will not boot. No heat spreader means clearance is not an issue, yet skipping the manual's slot order is the most common reason a working kit appears dead.

Questions about this item

Will the DDR5-5600 speed run at its rated 5600 MT/s on the Supermicro X14SDV-32C-SP3F?

The kit is an exact-match upgrade validated for that motherboard, so the memory controller will recognise the modules at full capacity and operate them at the rated DDR5-5600 speed.

What does the PC5-44800 designation cap in terms of bandwidth?

PC5-44800 corresponds to a peak transfer rate of 44 800 MB/s, which is the maximum theoretical bandwidth the DDR5-5600 interface can deliver.

Does the 288-pin RDIMM form factor fit the Supermicro X14SDV-32C-SP3F memory slots?

Yes — the board requires 288-pin Registered DIMMs, and this kit uses that exact form factor so it installs directly into the server's DIMM slots.
