Designed for Apple iMac and Mac mini

This 32GB kit contains two 16GB DDR4 2666 SODIMM modules built for specific Apple iMac and Mac mini models from 2019 and 2020. It targets owners of those machines who need more memory for multitasking or heavier workloads. The modules are non-ECC unbuffered with a 2Rx8 rank configuration and run at 1.20V.

Straightforward user installation

The SODIMM slots in the listed iMac and Mac mini units are accessible after removing the bottom cover or door, so no specialist tools are required. Align the notch on each 260-pin module with the slot key and press firmly until the side clips lock. A common issue is inserting a module at an angle, which leaves the contact pins partially seated and prevents the system from recognising the full 32GB capacity.

Verify your exact model identifier

Before ordering, confirm your Mac model identifier matches iMac19,1, iMac19,2, iMac20,1, iMac20,2 or Macmini8,1 using About This Mac or the label on the chassis. The kit supports the order numbers and EMC codes listed in the specifications. Machines outside this list, including earlier iMacs or later Apple silicon models, will not accept these DDR4 modules.
