OWC 3R2D42R432GB 32GB DDR4 3200 ECC Registered RDIMM 2Rx4 1.2V

Server DDR4 Upgrade Module

The OWC 3R2D42R432GB is a 32GB DDR4 3200 ECC Registered RDIMM built for workstation and server platforms that require registered memory. It operates at 1.2V with a CL22 latency and uses a 2Rx4 rank configuration across 288 pins. This module is not compatible with standard desktop computers that only accept unbuffered DIMMs.

Registered ECC Requirement

The single specification that decides fitment is the registered ECC design; the module will only work in systems that explicitly support registered DDR4 DIMMs with ECC enabled. Mixing this stick with unbuffered memory is not supported and will prevent the system from posting. Buyers who need memory for a consumer desktop or laptop cannot use this part.

Sustained Load Behaviour

Under continuous workloads the module maintains JEDEC-standard 3200 MT/s throughput at 1.2V without a heat spreader, relying on server chassis airflow for thermal management. The 2Rx4 organisation allows the memory controller to interleave ranks for steady bandwidth during long compute runs. Error correction operates continuously to detect and correct single-bit errors without interrupting service.
