NEMIX RAM 1.5TB DDR5 4800 ECC RDIMM Kit

This 1.5TB memory kit contains twelve 128GB DDR5 4800 registered DIMMs with ECC and CL40 latency. It is built for the SuperMicro X13SET-G and X13SET-GC motherboards in server and workstation deployments.

DDR5 4800 registered ECC speed and capacity limits

The modules operate at 4800MT/s (PC5-38400) with a 1.1V supply and 4Rx4 organisation. Registered ECC buffering adds latency versus unbuffered memory, and the 4800MT/s data rate is the baseline DDR5 speed rather than a higher bin.

Verify motherboard model

Confirm the board is a SuperMicro X13SET-G or X13SET-GC and that all twelve 288-pin DDR5 slots are free. The kit will not fit boards wired for other DDR generations or with fewer than twelve slots.

Questions about this item

Should I choose the 1.5TB kit or a smaller capacity for the SuperMicro X13SET-G motherboard?

The 1.5TB kit fills all 12 slots with 128GB modules, reaching the maximum supported capacity for this board.

What does the 4800 speed rating mean for real-world server workloads?

DDR5 4800 delivers 38400 MB/s peak bandwidth per module, providing high throughput for memory-intensive applications.

How does the 288-pin DDR5 RDIMM interface affect compatibility and performance limits?

The 288-pin registered DDR5 form factor ensures compatibility with the X13SET-G platform while the registered design supports stable operation at 1.5TB density.
