Q: 8. There seems to be some doubt whether or not the 64GB (4 X 16 GB) would be readable by a iMac 5K 27 Late '13 model, but upgraded to current operating standards. From what I've read so far, it looks like it will only read up to 32GB of memory. Will it see all 64 or just utilize the 32GB that it says it can be upgraded to? Much confusion here! Don't want to make a $829 mistake here...

A: I'm sorry, but the 2013 iMac tops out at 32GB's of RAM.
