So, I have question regarding possible after-market upgrades for the RAM and have little idea how to figure out these out for myself.

If I wanted to put 4 of the samsung 16GB RAM sticks into the 2011 iMac with the 3.4 GHz i7 linked below, would it work?

no... this will not work as this is 240 pin; you need SODIMM 204 pin RAM.

This is what you want: http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=A3272CC2A5CA7304

Also, are you talking about 4 sticks of 16GB ram for a total of 64GB? If so, no, that's crazy, unsupported, and a waste of time and money.

Apple reports the max as 16GB, so all you need is 4 sticks of 4 GB, as posted above.

"Apple Reports...."

Apple reported my previous 24" imac only supported 4GBs. I had 6GB running fine.

Newer ones support 32GB "unofficially" I believe. Unless OWC has it all wrong...

Remember, Apple "tells" you things because they want more money, ie, they want you to buy a Mac Pro.

Which is precisely why I chose those words.

I'm well aware more is likely possible, but just trying to clarify if he indeed meant 64GB.

Yes, i did indeed mean 64GB, but now I do see that's not possible. Looks like that i7 chip only supports up to 32GB. Thanks for the info though. Guess we'll be waiting for the Mac Pro update.
