NEMIX RAM 256GB DDR4 3200 ECC RDIMM Kit

This 256GB kit contains two 128GB DDR4 3200 registered DIMMs built for the SuperMicro M12SWA-TF WRX80 platform. ECC and registered buffering protect data integrity in mission-critical server and workstation workloads. IT professionals specify these modules for environments that demand validated stability. The kit arrives ready for immediate installation in compatible systems.

Capacity and headroom at 256GB with CL22 timing

Dual 128GB 4Rx4 modules deliver 256GB total capacity at PC4-25600 speed with CAS latency 22. Registered design and ECC support scale reliably across fully populated channels. The 1.2V operating voltage keeps power draw predictable under sustained load. Workloads exceeding 256GB will require additional memory slots or higher-density modules not included here.

Build integration for SuperMicro WRX80 motherboards

288-pin RDIMM form factor fits the M12SWA-TF WRX80 memory slots without adapters. Samsung, Micron or Hynix major-OEM chipsets ensure validated compatibility with the target platform. No heat spreader is fitted, so airflow clearance follows standard server chassis guidelines. Systems needing non-ECC, unbuffered or DDR5 memory cannot use this kit.

Questions about this item

Will the 4Rx4 288-pin DDR4 3200 modules run in the eight-channel WRX80 slots alongside any existing 3200 RDIMMs I keep?

Each 128 GB module is a 4Rx4 registered DDR4 3200 DIMM; the WRX80 platform supports eight channels, so populate matching slots per the motherboard manual for full bandwidth.

How can I confirm the ECC registered 256 GB kit is detected at the rated CL22 1.20 V after installation?

Enter BIOS or use a hardware monitor; the memory should report 256 GB total, DDR4 3200 speed, ECC enabled, registered mode and 1.20 V voltage.

Does the kit include only the two 128 GB RDIMMs or are heat spreaders and cables also supplied?

The package contains exactly two 128 GB 288-pin DDR4 3200 ECC RDIMMs; no heat spreaders, cables or extra accessories are included.
