SuperMicro WRX80 128GB Module

This NEMIX RAM module delivers 128GB of DDR4 3200 ECC registered memory in a single 288-pin RDIMM. It is built for the SuperMicro M12SWA-TF motherboard using the WRX80 chipset and uses a 4Rx4 rank structure with CL22 latency at 1.2V.

Registered ECC for Multi-Socket Builds

The registered design reduces electrical load on the memory controller, allowing higher capacities across multiple channels. ECC protection corrects single-bit errors to maintain data integrity in server and workstation workloads. No heat spreader is fitted, so airflow in the chassis must be adequate.

Replaces Lower-Capacity RDIMMs

Swapping smaller RDIMMs for this 128GB module increases total system memory without occupying additional slots. The upgrade is worthwhile when applications demand more addressable memory than the current configuration provides and the platform supports 4Rx4 modules at this speed.

Questions about this item

Does the 4Rx4 rank configuration limit how many of these 128 GB modules I can install on the WRX80 board?

The WRX80 chipset supports eight DDR4 channels, so a single 4Rx4 module occupies one channel; you can populate up to eight modules for 1 TB total if the board has eight slots.

How much heat does a 1.20 V 3200 MHz ECC RDIMM produce during continuous server workloads?

At 1.20 V the module runs cool enough for passive airflow in a server chassis; no heat spreader is fitted, so case fans must move air across the DIMM slots.

What motherboard feature must already be present for this registered ECC memory to function?

The board must implement DDR4 RDIMM slots with ECC support and the WRX80 chipset; standard unbuffered consumer boards will not accept registered modules.
