Mac Mini Late 2018 memory upgrade

This 32 GB kit provides two 16 GB DDR4 SO-DIMM modules rated at 2666 MHz with CL19 timings. The sticks are unbuffered, non-ECC and run at 1.2 V. They are built specifically for the Apple Mac Mini Core i7 3.0 (Late 2018) MRTT2LL/A.

Guaranteed compatibility and kit convenience

Computer Memory Solutions guarantees compatibility with the listed Mac Mini model. The matched pair enables dual-channel operation without manual selection. A limited lifetime warranty applies when purchased directly from the manufacturer.

Ideal for Late 2018 Mac Mini owners needing 32 GB

This suits users upgrading the MRTT2LL/A to 32 GB using both slots. Builders needing ECC, registered modules, different speeds or capacities beyond 32 GB should look elsewhere.

Questions about this item

Will the 2Rx8 rank configuration require any future adjustment or replacement?

The 2Rx8 rank is a fixed hardware characteristic of these 16GB modules; no adjustment or replacement related to rank is needed during normal use.

What limit appears first when the Mac Mini runs sustained workloads with this 2666 MHz CL19 kit?

The Mac Mini Late 2018 supports a maximum of 64GB across its two slots, so capacity is the first ceiling you reach under heavy sustained use.

How much heat and power do the 1.2V modules add during all-day operation?

Each module operates at 1.2V without a heat spreader, so thermal output and power draw remain at standard DDR4 SO-DIMM levels for continuous operation.
