32GB DDR4 3200 ECC RDIMM

This OWC module delivers 32GB of DDR4 3200 registered ECC memory for servers and workstations. It operates at 1.2V with CL22 latency and a 2Rx4 organisation on a 288-pin RDIMM. The part matches Kingston KSM32RD4/32HDR and KSM32RD4/32MRR specifications exactly.

Suited for registered ECC slots only

This memory fits systems that require registered ECC DDR4 RDIMMs and will not work in standard desktop boards. It cannot be mixed with unbuffered modules and is not compatible with consumer platforms that lack ECC and registered support.

Registered ECC DDR4 requirement

The single specification that decides fit is the registered ECC DDR4 RDIMM interface. Only motherboards and platforms designed for registered error-correcting DDR4 can use this module.

Questions about this item

How much power does this 1.2V DDR4 3200 ECC registered DIMM draw under sustained load?

The module operates at 1.2V and conforms to JEDEC standard DDR4 3200 specifications; actual power draw depends on the server platform and workload.

What must my server already support to use this 288-pin 2Rx4 ECC registered module?

The system must accept 288-pin DDR4 ECC registered RDIMMs, support DDR4 3200 (PC4-25600) speed, and provide 1.2V operation for registered memory.

Will this CL22 32GB ECC registered DIMM work in a system that currently runs DDR4 3200 ECC registered memory?

Yes, provided the existing DIMMs are also ECC registered, run at DDR4 3200, and the platform allows mixing 2Rx4 ranks; OWC recommends matching capacity, speed and manufacturer for best results.
