What I know so far is that it's already a lot faster than it was before and last year I used a MacBook Air with 4Gb (early 2014) to edit some videos with iMovie and create some music with Logic Pro. After the installation, I'll be running the Cinebench test and I might run another test as well to see how fast or slow my MacBook Pro (mid 2012) Model 9.2 is. I plan to watch some videos before attempting to install it. It comes with stickers which have printed on them the company name and the text 'Warranty Void if Removed', so that's great. I paid extra for a Special Delivery and the RAM arrived on January 11.

Eventually, I decided I couldn't get the kind of RAM I wanted for less than that price, so I gave in and bought some from a local company. I was looking around for some time for 2 X 8Gb RAM sticks at a price less than about €70 or US$80. My MacBook is fully updated to OS X El Capitan.I've read on similar threads that downgrading to OS X Yosemite might help?Īnother thought I had is that I've read that some people only swap one of the RAM chips, so I would have 1 of my original 2gb Ram chips and one 8gb upgraded chip, so having a total of 10gb which would be much better than my original 2x 2gb Ram.Thanks for your advice everyone! I'm in a part of Europe I don't want to mention which has developed a bad reputation, but I had nothing to do with causing this. I Have checked the system report and the new memory is being registered in the correct RAM slots, but it seems something somewhere else is going wrong. Now it sometimes restarts its elf even when im not using it, very annoying!

It has only done this since I put the new RAM in. But then all of a sudden about 5 mins into surfing the web the screen went blank and it started to restart itself. I have just upgraded my mid 2012 MacBook Pro to 16gb using 2x 8gb ATech DDR3 12800 1600MHz and to start with everything was fine, booted up quickly etc.
