Capacity and configuration

This NEMIX RAM kit delivers 128 GB across four 32 GB DDR5 RDIMM modules. It is built for Supermicro servers and workstations that require registered ECC memory at 6400 MT/s with a CL52 latency and 1.10 V operating voltage.

Who this suits and who it does not

The kit targets administrators expanding virtualisation hosts, database servers or AI inference nodes that demand registered ECC stability at the rated speed. Systems limited to lower DDR5 speeds, unbuffered DIMMs or non-ECC memory cannot use these modules.

Deciding specification

The registered ECC RDIMM form factor combined with a 6400 MT/s data rate and CL52 timing determines whether the memory matches the motherboard's qualified vendor list and the workload's reliability requirements.

Questions about this item

Will the four 32GB RDIMM modules fit in a standard 288-pin DDR5 server slot?

Yes, each module is a 288-pin DDR5 RDIMM designed for SuperMicro X14SBW-TF and compatible SuperMicro platforms.

What is the correct seating procedure for these registered ECC modules?

Align the notch on the 288-pin edge connector with the slot key, press straight down until both retention clips click, and verify all four modules are fully seated before powering on.

When should the 1.10V registered ECC RDIMM kit be replaced?

Replace modules if memory diagnostics report uncorrectable ECC errors, the system fails POST with memory beep codes, or instability persists after reseating and firmware updates.
