Review: Good memory to upgrade recent vintage iMacs - I bought this memory to take my 2020 vintage iMac from the 8GB it came with to 72GB. As others have noted, you do have to wait about 1 full minute after installing this memory for the iMac to boot. The memory has been great so far. No issues. I've noticed that my VMs run very fast now and Libre Office loads very quickly. Here's how the memory was configured on my iMac to begin with: Top. - Empty - 4GB - Empty Bottom - 4GB Now here's how I set it up after adding this memory (2 x 32GB) Top. - 4GB - 32GB - 4GB Bottom - 32GB Be careful when adding memory as it can be a little tricky to get the modules fully pushed in. I had 2 that actually weren't fully in after the change and my iMac wouldn't boot, so I checked, pushed in the loose ones, and it booted after about 1 minute. Note also the orientation of the slot at the bottom of the memory modules as this is designed to make the modules only go one way into their slots. If you feel like it won't fit, check the slot to make sure the module is facing in the correct direction. You can remove an existing module to compare and check the orientation.
