Upgrading Memory

I have a 27" iMac 2020. I have two memory slots empty and 8 GB used. Can I add another 8 GB or do all 4 have to be uniform?

Hello!


I have a 27" iMac 2020. I have two memory slots empty and 8 GB used. Can I add another 8 GB or do all 4 have to be uniform?

Yes, you an add another 8 GB of Memory for a total of 16 GB. When purchasing Memory for your specific iMac, you should only buy from Crucial:

https://www.crucial.com/.


Look for a 2 X 4 GB configuration (two 4 GB modules for 8 GB in total).


Other vendors' Memory for your specific iMac, such as OWC Memory, have issues in your model of iMac.
