I'm running an iMac 3.4 GHz Intel quad core i7. I want to upgrade my RAM from the installed 4GB (2X2GB). The Applecare reps tell me that I can't configure beyond 16GB (4X4GB); that higher RAM will not be recognized or even cause a problem. The guy at the Apple dealer (Microcenter) tells me that I can install two 8 GB chips in two additional slots and leave the 2X2GB chips in place and have a total of 20 GBs of RAM. The dealer is not making more money that way. It would actually be less.

What's the right answer?

That machine can be had direct from Apple with up to 32GB RAM installed (4x8).

 

The 20GB configuration will also work fine and yes, the system will see 20GB.

I have a May 2011 21.5" iMac with 32GB. It recognises all of it.
