    • Works like a charm!
Size: 16GB Color: 2 x 8GB
Mu purchase of 16 GB (2x8 GB sticks) of DDR 4 2666 ghz ram went smooth all of the way. It was delivered on time and very easy to install in my 2020 iMac 27". I figured I only needed 16 GB based on my Apple computer Activity Monitor assessment but decided I would try to add it to the existing 2x4 GB sticks I had. For the un-initiated: This computer uses 2 channels for ram. These both must be used or the effect will be decreased random access memory **availability**. There are 4 (four) slots for ram sticks. Channel A is slot 1 and 2, Channel B is slots 3 and 4. To work optimally, so I was led to understand by YouTube videos, the must carry the same amount. To illustrate, I now have 8 + 4 in Channel A and 8 + 4 in Channel B. If I had put this in any other configuration it would not work the same nor would it be optimal. In summary, I now have more than enough ram (there was no availability of 8 GB (2 x4 sticks). It was a bit more expensive than I had seen a year ago but that is life, I guess, you snooze you lose :^) ... show more

    • Upgraded memory of 2020 iMac 5k 27inch to 64gb effortlessly on
Size: 64GB Color: 2 x 32GB
I upgraded my iMac 2020 model 1 with 2x32gb today successfully. By following the instructions given by owc tech support, I swapped the two built in memory card with the owc memory card in the same slots (2 and 4). The iMac showed 64gb with 2666mhz speed and has the memory performance of 27999 MB (dual channel). The only catch is the manufacturer and one other field in the memory section of system report on iMac is is not populated properly. So far so good. Hope this helps for future buyers ... show more

    • Great quality, does what it’s supposed to do
Size: 32GB Color: 2 x 16GB
Great quality and worked flawlessly right away. Good value for the money and very simple to install. Just looked up how to do it on Google, no need to take the computer to Apple. They will charge you an arm and a leg! It’s very simple. You can do it yourself! I paid $100 for the memory, popped off the cover with the price of a button and installed the memory myself. Apple would’ve charged $400 to $500. Crazy. It literally takes 2 minutes. Very pleased with this product. Double check that it is compatible with your computer, memory is very specific. ... show more
