Purpose-built server memory

This NEMIX RAM module is a 128GB DDR5 registered DIMM with ECC, built for Supermicro X13DGU AI SuperServer platforms. It delivers 128GB in a single 288-pin stick so dense capacity can be added without occupying multiple slots.

Speed and timing gate

The module runs at DDR5 5600 (PC5-44800) with a CAS latency of CL46 at 1.1V. That combination of frequency, voltage and latency is the single specification that determines whether the memory will initialise and remain stable in the target Supermicro motherboard.

Suited for high-density AI nodes.

IT teams deploying GPU-heavy inference or training servers that require registered ECC memory in large per-slot capacities will match this part. Builders using standard desktop or workstation motherboards that accept only unbuffered non-ECC DDR5 cannot use this registered module.

Questions about this item

How does the 5600 MT/s speed translate to real throughput in a Supermicro server?

The module runs at 5600 MT/s, delivering the DDR5 data rate the Supermicro X13DGU platform expects for AI and HPC workloads.

What does the PC5-44800 rating limit in practice?

PC5-44800 confirms the 5600 MT/s transfer rate and registered ECC operation the motherboard requires.

Will the 288-pin 4Rx4 registered DIMM fit the Supermicro MBD-X13DGU memory slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the X13DGU DIMM sockets exactly.
