OWC 16GB DDR4 ECC Registered RDIMM

This 16GB DDR4 module runs at 3200MHz with a CAS latency of CL22. It is an ECC registered RDIMM built for workstation and server platforms. The single-rank 2Rx4 design operates at 1.2V and uses a 288-pin form factor. It is not compatible with standard desktop computers or unbuffered memory configurations.

Installation notes for registered ECC memory

Install the module into a compatible 288-pin DDR4 slot that supports registered ECC DIMMs. The system must explicitly accept registered memory; unbuffered slots will not work. Mixing this module with unbuffered DIMMs will prevent the system from booting. For best results, OWC recommends matching capacity, speed and manufacturer across all populated slots.

Check your platform before ordering

Verify that your motherboard or server chassis supports DDR4 ECC registered RDIMMs at 3200MHz. Confirm the maximum supported capacity per slot and the total number of available 288-pin slots. Ensure the BIOS or firmware is current enough to recognise JEDEC-standard PC4-25600 modules. This product is not suitable for systems that require unbuffered or non-ECC memory.

Questions about this item

How do I confirm the OWC 16GB DDR4 3200MHz module is running at PC4-25600 CL22 after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should show 3200 MT/s speed, CL22 latency, 1.2 V voltage, and ECC registered status for the installed DIMM.

What ships with the OWC 16GB DDR4 3200MHz RDIMM and is any extra hardware required?

The package contains one 16 GB 288-pin DDR4 ECC registered RDIMM (part 3R2D42R416GB); no cables, brackets, or additional components are included or needed for installation.

Which capacity and rank should I choose if I need a single 16 GB 2Rx4 registered ECC module for my server?

This exact part is a single 16 GB 2Rx4 DDR4 3200 CL22 registered ECC RDIMM; select it when your platform requires one module of that density, rank, and registration type.
