128GB DDR4 3200 ECC RDIMM Server Memory

This NEMIX RAM module provides 128GB of DDR4 3200 registered ECC memory in a single 288-pin DIMM. It operates at 1.2V with CL22 latency and a 4Rx4 rank structure using major OEM chips. The stick is validated for the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard.

Suits ASUS WRX80 workstations needing maximum

Ideal for IT professionals upgrading compatible ASUS server boards that accept 128GB 4Rx4 registered DIMMs. Not for consumer desktops or laptops that require unbuffered non-ECC memory. Builders needing lower-capacity modules or different rank configurations should look elsewhere.

Single 128GB 4Rx4 registered DIMM decides fit

The 4Rx4 organization and 128GB density determine whether the target platform can address this module. Verify the motherboard qualification list supports this exact rank and capacity per slot before purchase.

Questions about this item

Does my motherboard need registered ECC DDR4 slots to run this 128GB 3200 CL22 4Rx4 module?

Yes, the module is a 288-pin DDR4 RDIMM with ECC and registered buffering, so the board must support registered ECC DDR4 memory.

Can I mix this 128GB 4Rx4 stick with my existing 32GB 2Rx4 DDR4 3200 ECC RDIMMs on the same ASUS WRX80 board?

The board will run all modules at the lowest common speed and latency; 4Rx4 and 2Rx4 ranks can coexist if the motherboard firmware supports mixed-rank populations.

How do I confirm the 128GB stick is detected at 3200 MT/s with ECC active after installation?

Check the BIOS memory information screen for 128GB total, 3200 MT/s operating speed and ECC status reported as enabled or active.
