Apple iMac/Mac Mini DDR4 SODIMM

This 16GB DDR4 2666MHz module is built for Apple iMac and Mac Mini systems that accept 260-pin unbuffered non-ECC SODIMMs. It runs at 1.2V with CL19 latency and a 2Rx8 organisation using major OEM chips. The single-stick design lets you add capacity without filling every slot.

Mac owners adding memory.

The part suits users upgrading compatible Apple all-in-ones or compact desktops that specify PC4-21300 SODIMMs. It will not work in systems that demand ECC, registered or buffered modules, nor in laptops or boards limited to other DDR generations or pin counts. Check your model’s memory specification before purchase.

260-pin DDR4 2666 CL19 1.2V spec

The decisive figure is the 260-pin DDR4 2666MHz CL19 1.2V unbuffered non-ECC SODIMM profile. If your Apple system requires exactly that speed, voltage, latency and pin layout, this module matches; otherwise it will not fit or post. No other specification overrides this compatibility gate.

Questions about this item

What comes in the package and is anything else needed to install it?

The box contains a single 16GB 260-pin DDR4 SODIMM module. No extra parts or tools are required for installation in a compatible slot.

How do I decide between this 16GB stick and a lower-capacity alternative?

Choose this 16GB module when your system has a free SODIMM slot and the motherboard supports 16GB per slot at 2666MHz CL19 1.2V.

What does the 2666MHz PC4-21300 rating deliver once the module is seated in a real machine?

The module operates at 2666MHz with CL19 latency at 1.20V, providing the rated bandwidth when the platform accepts those timings.
