NEMIX RAM 128GB DDR5 5600 kit for SuperMicro

This NEMIX RAM kit provides 128GB of DDR5 memory across four 32GB UDIMM modules. It runs at 5600MT/s with a CAS latency of CL46 and operates at 1.1V. The modules are unbuffered, non-ECC, and built with 2Rx8 organisation using major OEM DRAM chips. They are validated for the SuperMicro C9Z890-MW motherboard.

Who this suits and who should look elsewhere

This kit suits administrators upgrading a SuperMicro C9Z890-MW workstation or server that accepts unbuffered non-ECC DDR5 UDIMMs. It is not for systems that require registered or ECC modules, nor for boards limited to lower speeds or different pin counts. Buyers needing error correction or registered signalling must choose a different specification.

The specification that decides fit

The decisive specification is the DDR5 5600 unbuffered non-ECC UDIMM form factor with 2Rx8 organisation at 1.1V. Only motherboards that explicitly support this exact combination will accept the kit without compatibility issues. The SuperMicro C9Z890-MW is the validated platform for this part number.

Questions about this item

Will my SuperMicro C9Z890-MW motherboard run this 128 GB DDR5 kit at the rated 5600 MT/s without manual tuning?

The kit is validated for the C9Z890-MW and ships at 5600 MT/s CL46 1.10 V; enable XMP or the equivalent DDR5 profile in BIOS to reach the rated speed.

Can I keep my existing 32 GB DDR5 modules and add this 4×32 GB kit for a mixed-capacity setup?

Mixing different capacities or ranks on the C9Z890-MW can prevent the board from training at 5600 MT/s; for best stability populate all four slots with this matched 2Rx8 kit.

After installation how do I confirm the system is using all 128 GB at 5600 MT/s CL46?

Open Task Manager → Performance → Memory or run CPU-Z; you should see 128 GB total, 5600 MT/s data rate and CL46 timings at 1.10 V.
