Review on CT2K4G3S1339M - Crucial 8GB Kit (2x4GB) DDR3 1333 MHz CL9 Memory for Mac, Enhanced SEO by Will Randles

I added this pair of memory modules to my mid-2011 iMac 27-inc to increase my total RAM from 4GB to 20GB. Although Apple's documentation states that 16 is the maximum, I looked at the capacity of this model and found that you can expand it up to 32GB. For those who don't have a clue (like me), the installation was very simple: 1 - Turn off your iMac. Touch the exterior of iMac to discharge it (static electricity) and unplug it from the power outlet. Place the iMac "face down" in the towel.2 - Unscrew the 3 screws from the memory compartment on the bottom of the iMac, remove the memory cover.3 - Leave 2 RAM modules in their slots (I had 2 RAM modules of 2GB each).4 - Insert 2 NEW RAM modules (8GB each) into 2 free slots.5 - Install the 3 screws of the memory cover, replace and switch on she an. That's all. When I look at the About This Mac > Storage screen, I go from: [ 2 GB ] [ 2 GB ][ ] [ ] to: [ 2 GB ] [ 2 GB ][ 8 GB ] [ 8 GB ] Hope that helps!
