## Description

Corsair's 4GB and 8GB Mac memory upgrade kits will help your system work better. With hassle-free compatibility and renowned Corsair reliability and support, they're a smart performance investment. Applications use memory, and some of the applications that run best on the Mac — photo and video editing — use lots of it. That's why outfitting your Mac with a Corsair Mac Memory upgrade kit is one of the best things you can do to maximize your system's performance and agility. With a Mac that's been upgraded to the maximum amount of memory it supports, you'll spend less time waiting for your applications to buffer data to the hard drive, and more time working — or playing. Upgrading memory can also be a cost-effective way to get more life out of your older system: before you trade up to a new one, just upgrade the memory.Compatible with macbook pro (13-inch: late 2011): macbook pro (13-inch: early 2011): macbook pro (15-inch: late 2011):macbook pro (15-inch: early 2011): macbook pro (17-inch: late 2011): macbook pro (17-inch: early 2011)

    Great memory and great price!
  

*by S***Y on Reviewed in the United States on January 21, 2012*

I chose Corsair memory because they are a reliable brand and make great computer products.  I also happen to use Corsair Vengeance memory in my desktop PC that has always been good to me.  So, I decided to go with Corsair once again.I originally bought the 8gb memory upgrade from here at Amazon, installed, and everything was working great for about a day or two.  I put my macbook pro (2011) dec edition to sleep, came back and bam!  Kernel panic error and was forced to reboot, only to get the same error message again and be forced to reboot.  I couldn't even run a memory test but obviously faulty ram was the cause of my issues.  I removed the Corsair memory and noticed there was an imperfection on one of the RAM contacts that I believe was causing my problems.  Luckily, I held onto the stock samsung memory and returned the defective memory to Amazon.Amazon immediately processed my return and I ordered the same 8gb upgrade from Corsair here at Amazon again.  I installed, ran memtest86 and let it run for almost 25 hours that included 14 full passes and ZERO ERRORS.  So once again Corsair does it again, another great quality product.....at least the second time around!  Thanks Amazon and thanks Corsair!  You both rule!Also, the 8gb upgrade makes a noticeable difference when running multiple applications.  My macbook pro is much snappier and able to multitask much faster with many programs open at once.  Buy Corsair, upgrade the memory yourself (instructions are included in the macbook manual) and don't get ripped off by paying the $200 for Apple to upgrade your RAM!

    My computer is like new again!
  

*by M***N on Reviewed in the United States on July 30, 2016*

I was completely out of space on my 2011 Macbook Pro. I did some research online and found that you can increase the memory (RAM) of the computer by ordering new chips to be put in with higher GB space. After looking online at different brands and reviews, Corsair seemed the best to me when comparing it with others.  This item shipped out the next day and arrived fairly quickly.  I was able to find a link on Apple's website that demonstrated how to do the upgrade step by step.  It took me no longer than five minutes to switch out the old memory for the new one. It has been a few hours that I'm using my computer with the memory and I have noticed that not only do my applications open quicker, overall my computer is also working faster and no longer lagging.  One thing I was uncertain of, but took the risk regardless, was if my documents/files would be deleted once I switched out the memory.  Thankfully, changing the RAM does not affect any of the documents you have in your computer. Everything was there after I completed the switch! This was a great price. Saved me from having to buy a new computer, yet it still works like its brand new!The picture is to show you what the packaging is like, I taped my old memory chips on to the back and the packaging got a little ruined. It was brand new and in perfect condition when it arrived, the picture is after I used it!- If my review was helpful, please let me know by clicking "yes."

    Easy fix for El Capitan problems
  

*by M***Y on Reviewed in the United States on March 20, 2016*

I installed OS El Capitan on my 5 year old MacBook Pro and then got the dreaded spinning rainbow. Every app I opened took FOREVER. So I cleaned up the computer, got things off the desktop, etc., etc. Tried 10 things then read about installing more memory and thought it was worth a try rather than buying a new computer. I looked up how to upgrade up to 8 GB on the apple website.  I have never been inside a computer before so I gave myself an hour to fix it, but it took me less than 5 minutes to upgrade. The directions are OK, but understand that the two cards sit right above one another and need to both be removed at the same time. And now everything opens immediately, switches between apps immediately. This was a very inexpensive and easy way to fix a very aggravating problem.
