Apple iMac and Mac mini upgrade

This 8GB kit contains two 4GB DDR4 2666MHz SODIMM modules built for select Apple iMac and Mac mini systems from 2019 and 2020. It runs at 1.20V with unbuffered, non-ECC 1Rx16 chips and carries Apple order-number certification for the listed models.

Straightforward SODIMM installation

The 260-pin modules slot directly into the memory compartment on compatible iMac and Mac mini units without tools or firmware changes. No heat spreader is fitted, so clearance inside the slim chassis is not affected. Mixing with existing modules of different speeds or ranks may prevent booting, so matching the kit specification is advised.

Ideal for supported Mac owners needing 8GB

Owners of the specified iMac 21.5-inch 4K, iMac 27-inch 5K and Mac mini models who want a simple capacity increase will find this kit a direct fit. Buyers with other Mac generations, Windows laptops, or systems requiring ECC or registered memory should look at something else.

How can I verify the kit is running at 2666 MHz after installing it in my iMac?

Open About This Mac, click System Report, choose Memory and confirm each 4 GB module shows DDR4 2666 MHz speed and 1.20 V voltage.

What comes in the box and do I need any extra tools for a Mac mini 2018 install?

The box contains two 4 GB DDR4 260-pin SODIMM modules; no tools are required for the Mac mini 2018 memory slot.

Should I choose the 8 GB kit or a larger capacity for my 27-inch iMac 2020?

The 8 GB kit (2 × 4 GB) matches the factory slot count; select a larger kit only if your model supports more than two modules.
