Just to add to your peace of mind, my 21" iMac (prior version) is working beautifully at 2x2 and 2x4 (12 total) GiB. Way faster than before (4GiB really isn't sufficient for what I do), and I don't see any oddball slowdowns.

I got good quality memory that matched the MHz (1333) of the existing memory. Works like a charm.

That said, I didn't try going to 16 GiB, so I can't vouch that 16GiB isn't faster than 12, but for me, 12 is more than sufficient at the moment. When the time comes, I'll switch out the older 2x2 sticks, but I don't see that it will make a huge improvement.

Is it ok to mix 2 GB and 4 GB DIMMS in an iMac (mid 2011)?
Jesus highlights Deuteronomy 6:5 as the greatest commandment in the law.  This commandment highlights three aspects of loving God, specifically with our hearts, our souls, and our strengths.


  Love the LORD your God with all your heart and with all your soul and
  with all your strength.  Deuteronomy 6:5 NIV


What is distinct about each of these?  Specifically, what does it look like to love God with all our hearts?  What does it mean to love God with all our souls?  What does it mean to love God with all our strengths?
