Upgrading the RAM from 8 to 16 GB
I've decided to upgrade my RAM from 8 to 16. I have iMac 21.5, 4k 2017. pro 555.
I saw on Apple's official site, that I can upgrade my system to only 16 GB maximum.
Can I put in two 16 GB modules into this model?
On this site I found that I can buy 16 GB RAM. But, this Mac has 2 slots for RAM. Should I fill both slots (do I need two 8 GB modules?) Or, I can put only one 16 GB module in and it will be enough?
Ist dies eine gute Frage?
