Mac-Ready DDR4 Kit

This Timetec 16 GB kit delivers two 8 GB DDR4 2666 SO-DIMMs built for Apple iMac and Mac mini models from 2018 to 2020. It targets owners of those machines who need more memory for everyday workloads without changing voltage or form factor.

SO-DIMM Slot Constraints

Each module uses the 260-pin DDR4 SO-DIMM standard at 1.2 V with CL19 latency. The Mac mini (Late 2018) provides only two slots, so this kit fills the system completely and leaves no room for further expansion.

16 GB Practical Headroom

The 16 GB total suits multitasking, office suites and light creative tasks on supported iMac and Mac mini models. Machines that already run 32 GB or that require ECC or registered memory cannot use this unbuffered non-ECC kit.

Questions about this item

Should I choose the 16GB kit or a 32GB option for my Mid 2020 iMac?

The 16GB kit contains two 8GB modules and fills both slots on a Late 2018 Mac mini. A 32GB option would require 16GB modules if your iMac has four slots.

What does the 2666MHz speed mean for my iMac 19,1?

The modules run at DDR4 2666 (PC4-21300) with CL19 latency at 1.2V, matching the factory memory specification for 2019 and 2020 27-inch iMac models.

Will the 260-pin SO-DIMM fit the memory slots on my Late 2018 Mac mini?

Yes, the 260-pin DDR4 SO-DIMM form factor is the correct physical interface for the Late 2018 Mac mini (8,1) and the listed iMac models.
