2020 iMac i9
As with my Synology memory upgrade, Arch shipped this memory to me quickly. The iMac had no problem recognizing the memory and has been very stable in my primary use with Adobe Lightroom and Photoshop. Once interesting note is when this memory, combined with the 8GB of Apple memory that shipped with the iMac showed a bus speed of 2133Mhz instead of the native 2666Mhz. Once the Apple memory was removed, the speed of the Arch Memory was correctly reported. I am not sure why that happened, but the 64GB is plenty of capacity for my needs. I very much recommend Arch memory for any of your computing needs.
