OWC 16GB DDR4 2666MHz Desktop Module

This OWC module adds 16GB of DDR4 memory to a desktop PC, workstation or NAS. It runs at 2666MHz with a CL19 latency and operates at the standard 1.2V. The unbuffered, non-ECC design uses a 288-pin UDIMM form factor.

Suits standard DDR4 desktops.

The stick fits systems that accept PC4-21300 unbuffered UDIMMs and will also run at 2133MHz or 2400MHz if the platform requires it. It is not compatible with servers or workstations that require registered or ECC memory.

16GB single-module capacity

A single 16GB module fills one slot and provides that full capacity without needing a matched pair. If the board has a lower per-slot limit or the build requires multiple smaller modules, a different kit would be necessary.

Questions about this item

Will this 2666MHz DDR4 UDIMM run at the correct speed if my current motherboard only supports 2133MHz or 2400MHz memory?

Yes, the module is backward compatible and will automatically operate at 2133MHz or 2400MHz when installed in a system limited to those speeds.

How can I confirm the OWC 16GB module is running at 2666MHz with CL19 latency after installation?

Check the memory speed and timings in your system BIOS or use a utility like CPU-Z to verify it reports DDR4-2666 and CAS 19.

Does the single 16GB stick include a heat spreader or any extra cables I might need for my desktop build?

The module has no heat spreader and requires no cables; it is a bare 288-pin UDIMM ready to insert into a desktop DIMM slot.
