Just ordered a 2020 27" iMac and looking to buy more RAM(32) so I will have a total of 40 RAM. I'm don't no a lot about computers that why I have always bought Apple. Looking on line and so many different venders and Brands of RAM. What recommendations would you have for me. Thank You in advance !!
iMac, macOS 10.13
Keith is correct. I bought a 2020 27" iMac and did the same thing you are considering. Using high quality RAM (OWC is what I bought too) is extremely wise. Also, what is important on the 2020's is the configuration you install it in. Put the original RAM in slots 1 & 2 (the top 2 slots) and the new OWC RAM in slots 3 & 4. Why, because doing it this way ensures the RAM runs at the speed it is rated at. Here are photos of my installation, please note the slots the RAM was installed in and the speed it yielded:

One last Question I'm on the OWC website ordering the 32 RAM(2X16) and it has the Date Rate as DDR4-2666. Yours says 2667 in the photo will I be ok ordering the 2666. I don't se the 2667 on there web site. Sorry If this makes me look stupid I know very little about this LOL. Thank You again Burt
Thank you for this information! I have the exact configuration (4x2 or 8 GB) on the new 2020 27" iMac that I just got. Coincidentally, I ordered the exact 16x2 (32 GB) upgrade from OWC earlier before I read this post. Now I don't have to experiment on which slots to put the memory modules. Very helpful!
You too. BTW, if you feel this thread has been answered please mark it as such, it may help another user.
Go to OWC (otherworldcomputing) they will tell you exactly what kind of RAM to buy.
Thank You Keith OWC was one of the Brands I was looking at.
Thank you for the information very informative!
Your welcome.
2666 is just fine.
Thank You again have a Happy Thanksgiving !
Your welcome!
