Compatible Mac Mini 2018 Memory

This 16GB DDR4 SO-DIMM module is built specifically for the Apple Mac Mini Core i3 3.6 (Late 2018) MRTR2LL/A. It operates at 2666MHz with CL19 timing and runs at the standard 1.2V voltage. The unbuffered, non-ECC design matches the system's original memory architecture.

Suits single-slot upgrades; not for dual-kit buyers

The single-stick package suits owners filling one empty slot or replacing a smaller module in the two-slot Mac Mini. Buyers who want a matched pair for dual-channel performance should look at a two-module kit instead. The module uses major-brand chips and carries the supplier's lifetime warranty when purchased directly.

260-pin DDR4 2666 CL19 specification

The decisive specification is the 260-pin DDR4 2666MHz CL19 interface, which must match the Mac Mini's memory controller exactly. A different pin count, speed grade or latency will prevent the system from booting. Verify the part number CM2048642666SO against your model before ordering.

Questions about this item

Will the 260-pin DDR4 SO-DIMM fit the two memory slots in the 2018 Mac Mini?

Yes, the module uses the standard 260-pin DDR4 SO-DIMM form factor that matches the two SO-DIMM sockets in the Late 2018 Mac Mini.

What is the correct orientation for inserting the module into the Mac Mini slot?

Align the notch on the 260-pin edge connector with the key in the SO-DIMM slot, press firmly until the side clips click, then verify 16 GB appears in System Information.

Does the 1.2 V DDR4 module require any firmware update or special configuration after installation?

No, the unbuffered non-ECC DDR4 2666 CL19 stick is plug-and-play; the Mac Mini automatically detects the 16 GB capacity at 1.2 V without BIOS changes.
