iMac 27" 2017 RAM upgrade to 24 GB but won't power up!
My current RAM is two 4 GB modules (2x4) by default - total of 8 GB
I bought the same frequency two 8 GB modules (2x8) PC4-2400 to get the total of 24 GB
Now its not powering up.
If I removed one of them, and leave 3 modules it’s OK, but I only get to 20GB. If I add the last 4 GB module it will not power up.
Any Idea or solution for this?
