8GB DDR4 2666MHz SODIMM for Apple Mac

This 8GB DDR4 2666MHz SODIMM module is built for compatible Apple iMac and Mac mini systems from 2019 and 2020. It uses a 260-pin form factor and operates at 1.20V without ECC or buffering. The single-rank 1Rx8 design fits the memory slots in the listed iMac 21.5-inch, iMac 27-inch and Mac mini models.

DDR4 2666MHz speed ceiling on supported Macs

The DDR4 2666MHz interface sets the maximum data rate for this upgrade. Systems that officially support DDR4 2666 will run the module at that speed; Macs limited to a lower memory bus will downclock it automatically. No manual configuration is required because the module follows standard JEDEC timings for PC4-21300 operation.

8GB capacity adds headroom for everyday workloads

An 8GB module doubles the base memory on many entry-level configurations, allowing smoother multitasking with browser tabs, office suites and creative apps. Workloads that exceed the installed capacity will still rely on swap storage, so professionals handling large video timelines or virtual machines may need additional modules where the chassis permits.

Questions sur cet article

Should I pick the 8 GB module or a different capacity for my 2019 iMac?

This listing is a single 8 GB SODIMM; the iMac 2019 and 2020 models accept two modules, so you can add one now and a second later to reach 16 GB total.

What does the 2666 MHz rating deliver inside a real Mac mini 2018?

The module runs at 2666 MT/s with 1.20 V, giving the Mac mini its maximum supported memory bandwidth for faster app loading and smoother multitasking.

How does the 260-pin DDR4 SO-DIMM interface limit performance?

The 260-pin DDR4 SO-DIMM slot caps the data rate at 2666 MT/s (PC4-21300), so this module already hits the ceiling the Mac’s memory controller allows.
