Exact-match server kit

This NEMIX RAM kit delivers 256GB of DDR5 memory as 16 modules of 16GB each. It is built for administrators upgrading a Supermicro H13DSH motherboard that requires registered ECC RDIMMs. The kit arrives new and ready for full-population deployment.

Registered ECC RDIMM

Each module runs at DDR5 4800 with a CL40 latency at 1.1V in a 1Rx8 configuration. The 288-pin registered design buffers address and command signals so the memory controller can drive all slots at rated speed. On-die ECC corrects single-bit errors before they reach the operating system.

Full-slot population

Populating every DIMM slot with matched 1Rx8 registered modules lets the platform reach its maximum supported capacity without mixing ranks. The kit eliminates the guesswork of sourcing individual sticks that might differ in vendor or timing. Buyers needing a different capacity or a UDIMM form factor should look elsewhere.

Questions about this item

Will the 4800 speed run at full rate when all sixteen slots on the H13DSH are populated?

The kit is spec-matched to the board's memory-population rules, so the registered ECC modules are recognized at the full 256GB capacity and operate at the rated DDR5-4800 speed across every slot.

What does the PC5-38400 label mean for real-world throughput on this motherboard?

PC5-38400 is the peak transfer rate designation for DDR5-4800; on the H13DSH the registered DIMMs deliver that bandwidth provided the CPU memory controller supports the full data rate.

Do these 288-pin RDIMMs fit the H13DSH slots without any adapter or special mounting hardware?

Yes, the 288-pin registered DIMM form factor matches the slots on the Supermicro H13DSH exactly, so they install directly with no adapter required.
