Greetings...

Forgive me if this has been discussed before. I did a search but did not find a thread on this topic.

I have the base model 2011 21.5 iMac. (2.5GHz i5, 4 GB RAM, etc.)

In the Apple Store, this model is not upgradeable to 16 GB. The max configurable upgrade is 8 GB. In the System Profiler, it shows there are 4 memory slots. I assume I can upgrade the RAM myself to 16 GB (4GB x 4). Is my assumption correct or is there a limitation with the i5 chip that can only address a maximum of 8 GB?

Thanks in advance for any insight...
 
I was just about to make a post about this, but if anyone with the baseline 21.5 inch can verify that you can add your own 4gb DIMM's for a maximum of 16gb's that would be nice.

All iMac models since the late-2009 support up to 16GB of RAM and the mid-2010 and later 27-inch iMacs support up to 32GB.

For more information on adding RAM to your iMac, see here.
 
According to Everymac.com, this system is upgradable to 16 GB ram. Unofficially, it can be boosted to 64 GB. Might be only 32, I forgot...
