256GB DDR4 3200 ECC RDIMM Kit

This NEMIX RAM kit provides 256GB of DDR4 3200 memory in four 64GB modules. The modules are ECC registered RDIMMs with CL22 latency and operate at 1.2V. They are designed for SuperMicro M12SWA-TF WRX80 motherboards and use major OEM chips from Samsung, Micron or Hynix.

Suited for ECC server upgrades.

The kit targets administrators expanding memory on compatible SuperMicro server platforms that require registered ECC RDIMMs. Builders using consumer desktop boards without ECC support or systems that accept only unbuffered UDIMMs should look at other memory types.

Four matched modules simplify population

The package contains four identical 64GB RDIMMs pre-validated as a matched set. This allows straightforward population of four DIMM slots without mixing modules from different lots, helping maintain stability under sustained server workloads.

Questions about this item

Does my motherboard need to support DDR4 3200 ECC registered RDIMM modules with 288 pins and 1.2V operation?

Yes, the kit requires a DDR4 platform that accepts 288‑pin ECC registered RDIMMs running at 1.2V and 3200 MT/s.

Can I mix these 2Rx4 CL22 registered DIMMs with older unbuffered ECC UDIMMs in the same server?

No, registered and unbuffered ECC DIMMs cannot be used together; the memory controller will not initialise a mixed configuration.

How can I confirm the full 256 GB kit is detected at 3200 MT/s with ECC active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode to verify 4 x 64 GB modules at 3200 MT/s with ECC enabled.
