Hi!
I have iMac (Retina 5K, 27 inç, 2019) so I bought mac memory for ram upgrade (full name: CORSAIR Mac Memory 64GB (2 x 8GB) DDR4 2666MHz C18 Memory Kit) But behind the box it says it's compatible for iMac 5K Display (Mid-2017) ve Mac mini (Late 2018). What does it mean, is it not compatible for my mac or it's just base criteria? Will this cause performance issues?
Thanks in advance
iMac 27″, macOS 11.0
Welcome to the Apple Support Communities.
I strongly suggest you don't use that brand of RAM. Rather, use either Apple or Crucial.
Apple official RAM: Apple Memory Module DDR4 2666MHz SO-DIMMS - Apple Store.
Crucial RAM: Apple iMac (Retina 5K, 27-inch, 2019) Memory - Crucial.

Hi again! (my sisters account but it's me:)
I bought this ram but now my mac doesn't start:( I opened this discussion. What do you think is the problem?
Hi Jack,
I can't find Crucial in my country. There is Kingston Bigboy and Corsair so I don't have many options unfortunately:/
Edit: I found on amazon ship to Turkey but it's expensive compare to Corsair. :(
Ok last one:)
16 gb is not available right now. Do you think 32 is better? I read that there is not much difference between 24 and 40 gb ram.
I want it for adobe programs
Thank you so much for your answers!
I purchased this for my 2020 27' iMac.
OWC 32.0GB (2 x 16GB) 2666MHz DDR4 PC4-21300 SO-DIMM 260 Pin Memory Upgrade, (OWC2666DDR4S32P), for 2019-2020 27 inch iMac (iMac19,1 iMac20,1 iMac20,2), 2018 Mac Mini (macmini18,1) and PC laptops
OWC and Crucial have been the gold standards of Mac RAM for years.
I've been here 20 years and have lost count of the posts that reported issues with Kingston and Corsair RAM. The problem is the both of those offer two quality tiers. The top tier is usually Mac-friendly but RAM is so cost sensitive that resellers usually only stock the cheap stuff.
Therefore it is hard to find the better quality versions of either Corsair or Kingston, so I avoid them entirely.
OWC has partners outside the US: https://www.owcdigital.com/reseller/resellers
For Adobe apps, 32GB would be better.
There is a big difference! :-)

What country are you located in?
-Jack
Turkey.
I found on amazon ship to Turkey but it's expensive compare to Corsair. :( Is it that bad?
It does appear Crucial is on Amazon for Turkey.
What RAM amount were you looking to upgrade to?
-Jack
Yes it does but its double price:/
2x8 or maybe 2x16
So do you think Corsair is a no go?
I found almost the same price :) Thanks
But I am still curious about my question. All criterias are compatible for my mac but it's says it's compatible only for those I write above. Why is that?
I honestly do not know. I am not familiar with Corsair.

Ram upgrade with Corsair Mac Memory
