Mac Mini 2018 DDR4 SODIMM

This 16 GB DDR4 2666 CL19 module is built for the Apple Mac Mini 2018 Macmini8,1. It uses a 260-pin SODIMM form factor with unbuffered non-ECC chips from major OEM suppliers. The single 16 GB stick upgrades the system to its maximum supported capacity in one slot.

Sustained workload stability

Every unit undergoes rigorous stress testing under load before shipment. The 1.2 V operating voltage and CL19 timings maintain consistent throughput during extended compile, render or database sessions. No heat spreader is fitted, relying on the Mac Mini internal airflow for thermal management.

Direct-fit 260-pin layout

The 2Rx8 rank organisation matches the factory memory configuration for plug-and-play compatibility. Installation takes minutes by accessing the SO-DIMM slots behind the bottom cover. No additional cables, brackets or firmware steps are required for the upgrade to be recognised.

Questions about this item

How much power does the 1.2 V DDR4 2666 SODIMM draw when the Mac Mini 2018 runs all day?

The module operates at the standard 1.20 V DDR4 voltage, so power draw stays low and heat output remains minimal during continuous use.

What must the Mac Mini 2018 already have for this 260-pin 16 GB stick to work?

An available SODIMM slot that accepts DDR4 2666 PC4-21300 non-ECC unbuffered memory; the 2018 Mac Mini uses this exact interface.

Will this CL19 2Rx8 module run alongside the original 8 GB DDR4 2666 stick Apple shipped in the 2018 Mac Mini?

Yes, both run at DDR4 2666 with matching voltage and rank architecture, so the system will operate in dual-channel mode without timing conflicts.
