I have a: MacBook Pro 15-inch, Mid 2012 Processor 2.3 GHz Intel Core i7 Memory 4 GB 1600 MHz DDR3 Graphics Intel HD Graphics 4000 384 MB Software OS X 10.8.4 (12E55) I would like to bring this machine up to 16GB of Ram. Google photo editing software for mac. I was looking at Crucial and also Mac Memory by RamJet. Cruical seems pretty good based on reviews but something that I've noticed is that the Mac Memory by RamJet folks say they sell 'Non-Stacked Ram' and that it's got lower power consumption and produces less heat then the cheaper stacked Ram. The excact claim is copy & pasted below.

So whats the deal, is one better then the other? • Non-Stacked IC's: Ramjet uses a Non-stacked module for the 8GB DDR3 module for the MacBook Pro. The cheaper stacked IC variety of 4GB SO-DIMM draws more power, which increases heat and decreases battery life.

Feb 14, 2016 - MacBook Pro (13-inch, Mid 2012). Official specs support up to 8 GB using two 4 GB 1600 MHz ram. They are both the same. Apple Support.

Ramjet ONLY uses premium non-stacked chips.**. I have a mid-2012 Macbook Pro 13'with the original 4gb of RAM. I ordered 16Gb of memory from Crucial and, after three attempts and three returns I tried OWC. Same story, multiple returns and attempts with no luck.

During my attempts with OWC they had me do a number of key stroke combinations. One of them corrupted my OS and had to have Apple do a clean install which wiped out my applications. I restored files from my back up which I do every day. A tech from OWC said this is a known problem with some mid-2012 Macbooks but they don't have a solution yet. I'm going to upgrade to 8Gb and hope that it works. At this point, even though I have no problem swapping out memory modules, I'm going to let the Geek squad do it, so if it doesn't work it's their problem.

I can bring my own memory but they have them there. I'm just tired of returning and working with tech support multiple times. Any thoughts or opinions would be welcome.
