256GB DDR4-3200 ECC RDIMM kit

This NEMIX RAM kit delivers 256GB of DDR4-3200 registered ECC memory in a matched pair of 128GB modules. It is built for the Supermicro X12QCH+ motherboard and meets the board's requirement for 288-pin RDIMM form factor, 2Rx4 rank structure and 1.2V operation. The CL22 timing matches the controller specification so the system recognises the full capacity at rated speed.

Registered ECC architecture

Registered buffering reduces electrical load on the memory controller, allowing every slot to run fully populated at the rated 3200 MT/s without signal degradation. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots in production workloads. The kit is validated against the Supermicro X12QCH+ population rules so installers can follow the manual's approved DIMM order without guesswork.

Suited for capacity-bound server upgrades

This kit suits administrators expanding a Supermicro X12QCH+ platform to its maximum supported memory where registered ECC and 2Rx4 density are required. It is not for desktop or workstation boards that accept only unbuffered UDIMMs, nor for systems limited to lower single-module capacities or different pin counts. Builders needing SODIMM, non-ECC or lower-voltage modules should look elsewhere.

Questions about this item

Will the 2Rx4 ECC RDIMM modules need periodic replacement under continuous server workloads?

The modules are built with major OEM Samsung, Micron or Hynix chips and carry a lifetime replacement warranty; no scheduled replacement is required for the DDR4 3200 1.20V 288-pin kit.

What sustained-use limit appears first when the 256GB kit runs at full DDR4 3200 speed all day?

The registered ECC design offloads the memory controller so every slot runs fully populated at rated CL22 1.2V without throttling; the first limit is the motherboard's maximum supported capacity.

How much heat and power does the 2x128GB RDIMM kit produce during 24/7 operation?

Each 128GB module operates at 1.2V without a heat spreader; the registered architecture keeps power draw low and thermals manageable inside a Supermicro X12QCH+ chassis.
