Capacity and purpose

This NEMIX RAM module delivers 128GB of DDR5 ECC registered memory in a single 288-pin RDIMM. It is built for SuperMicro B13DET server and workstation platforms that require high-density, error-correcting modules.

Build integration

The stick operates at 5600MHz PC5-44800 with CL46 latency at 1.1V and uses a 4Rx4 organisation based on major OEM Samsung, Micron or Hynix chips. It fits any qualified DDR5 RDIMM slot on the target motherboard and requires no heat spreader, leaving clearance for dense CPU cooler arrangements.

Fit and alternatives

This module suits administrators upgrading a compatible SuperMicro system to its maximum supported density per slot with registered ECC reliability. It is not for desktop boards that accept only unbuffered non-ECC UDIMMs, nor for platforms limited to lower speeds or capacities per slot.

Questions about this item

Will the CL46 latency become a bottleneck under sustained server workloads?

CL46 is the rated CAS latency for this DDR5 5600 module. It is the primary timing limit you will see under continuous load.

How much heat and power does a single 128 GB stick draw when running all day?

The module operates at 1.1 V with no heat spreader. Power scales with capacity and data rate, so expect typical DDR5 registered DIMM thermals for a 128 GB 5600 MT/s part.

What must the SuperMicro B13DET already have to accept this 288-pin RDIMM?

The board needs an available DDR5 RDIMM slot and a BIOS that supports 4Rx4 registered ECC modules at 5600 MT/s.
