Capacity and configuration

This NEMIX RAM kit provides 128GB of DDR5 ECC registered memory in four 32GB modules. It is built for the ASUS Pro WS WRX90E SAGE SE workstation motherboard. The registered design and error correction target workloads that demand data integrity and full-channel population.

Suited for stability-focused builds.

IT professionals and workstation integrators who need validated compatibility with the named ASUS platform will benefit from the tested kit. Builders seeking low-latency timings, heat spreaders or consumer XMP profiles should look at standard UDIMM alternatives instead.

Registered ECC RDIMM form factor

The modules are 288-pin DDR5 RDIMMs with a 1Rx4 organisation, CL46 latency and 1.10V operating voltage. Only systems that accept registered ECC DDR5 memory can use this kit; consumer desktop boards cannot.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the ASUS Pro WS WRX90E SAGE SE motherboard slots?

Yes, the kit uses standard 288-pin DDR5 RDIMM form factor that matches the motherboard's DDR5 RDIMM slots.

What BIOS setting or population order is required when installing all four 32GB modules on the ASUS Pro WS WRX90E SAGE SE?

Install one module per memory channel following the motherboard manual's population sequence, then enable ECC and registered mode in BIOS.

How do I know when the ECC registered modules need replacement?

ECC corrects single-bit errors silently; replace modules when the system logs uncorrectable multi-bit errors or repeated corrected-error thresholds are exceeded.
