Before I installed the memory, my MacBook Pro showed I had 4GB 1333 MHZ DDR3.
After the installation of the memory, my MacBook Pro showed I had 8GB 1333 MHZ DDR3.
Installation took 5 minutes.
Place a towel on a table, turn your computer over and place it on the towel.
Remove all screws that hold the back cover in place. The upper 3 screws are longer than the others.
Make sure you do not loose any screws as they are very small. I made sure that I used the same screw in the same hole it came out of. The cover should then come right off.
You will see the memory. It is held in by a plastic clipping device. Gently spread the plastic clip and slowly pull out the upper memory module. Do this also for the lower module.
When you pull out the module make sure you place it on the table so you know the exact way the new module will go into the computer.
Start with the lower module and gently place it in the memory slot. Do this very slowly and it should fit in perfectly. Place the upper memory module in next.
Place the back cover on the computer and use the screws to hold the cover in place. Do not tighten the screws firmly until all the screws are in. They should all go in smoothly.
Tighten all screws, but don't tighten them to much.
Turn on your computer, and click on the black Apple, click about this Mac. Your computer will then show the new memory has been installed.Just installed the Corsair 8 GB (2X4 GB) Memory and was instantly recognized by my week old iMac.
This is our first iMac after several years of PC usage.
Forget about the low star rating, the complaint was not about the product quality and handling, but a mistake on product description.I bought this for a macbook pro mid 2010 13" core 2 duo. It didn't work at all. I contacted corsair tech support who only seems to have a web form. They told me to try dimms separately, which I replied that I had done and 24 hours later I have heard nothing more from them. The guy at the apple store said this:
Even though ddr3 is supposed to be backwards compatible, this is NOT TRUE FOR APPLE. If your machine came with 1066MHz memory, you have to get 1066 memory, and you can't buy 1333 memory instead.
Anyway, I couldn't find the answer to that question on the internet prior to buying, maybe this review will help someone.
The packaging says compatible with macbook pro, but it's only compatible with certain ones. And corsair's website sucks for telling you which one and explaining backwards compatibility.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!Good RAM I would love 12Gs yet 8GBs does a great job. Thanks Amazon for the speedy response and the good.
