Corsair Mac Memory Upgrade Kits: Guaranteed Performance, Compatibility, and Support.

Corsair Mac memory module
The DDR3 SODIMM format is compatible with virtually all modern Mac computers.

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.

One of the best ways to improve your Mac's performance

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 Corcair 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.

Tested at Apple Developer Compatibility Labs for Guaranteed Performance

Corsair's Mac memory kits are guaranteed to work with any Mac desktop or laptop that supports 4GB DDR3 SODIMMs, including most iMac, Mac mini, MacBook, and MacBook Pro models offered by Apple since 2009. See the compatibility list below for details.

Not sure if your older Mac will work with 4GB DDR3 SODIMMs? Get in touch with us, and we'll help.

Limited lifetime warranty, support and service

Corsair has been making high-performance memory for just about as long as high-performance memory has existed. Countless customers worldwide rely on Corsair for performance, reliability, and value. Our reputation is important to us, and that's why all Corsair DRAM products are backed by a limited lifetime warranty. If you ever need help, we're available by phone, email, and web forum.

Size: 8 GB Verified Purchase
I have used lots of Memory modules over the years, and Corsair has come to be one of my top choices when making a purchase. I recently obtained the Corsair [Apple Approved] 8GB Dual Channel DDR3 1066 PC3-8500 DDR3 Memory for my Macbook Pro 13" (Late 2009 - 2010 model). The memory itself worked on boot up no issues, and as far as the installation on the macbook pro, its not so bad. Granted the install is a lot different than that of the white MacBooks, but it is still pretty simple. All that is required is a small screwdriver and some patience. There are many tutorials on how to do this on Youtube, pretty much its as simple as removing 10 little screws (I would highly recommend keeping them in order, as at least 3 of the screws are longer and must go back in specific holes) and having somewhere to place them safe so they don't fall or get lost. ** Of course as always due care is required when touching or changing components inside your computer, things like a simple static charge on your fingers can be an issue (like when you rub your socks on the ground and shock your friend... not so funny with a computer) **

One thing that I noticed while installing my memory, is that the memory type required by the macbook pro changed sometime between 2010 and 2011 so you may want to verify your memory type in "System Profiler" which can be found in your Utility Folder on your Mac. That will usually tell you how much memory you have and what type (i.e. DDR3 1066, or some other type). If you need to know your maximum allowable/recognizable memory, I would recommend searching your model number on Apples Support page.

Size: 8 GB Verified Purchase
I purchased this 8GB kit to upgrade the 4GB of RAM that came with my mid-2010 model MacBook Pro. I settled on the Corsair after reading all sorts of reviews online regarding brands. Basically, "RAM is RAM" was the overwhelming sentiment I got from all the research. That in mind, the price was great (cheapest here on Amazon), it was "Mac tested," and I'm extremely happy with my decision.

Using the detailed instructions provided on Apple's website for upgrading RAM, I was able to install and start using my computer again in less than 10 minutes. Basically, removed the bottom, popped out the old RAM, plugged in the new RAM, fired up the computer, and voilà. I should point out that, while I have upgraded RAM on previous PC once before, I'm definitely not a pro.

The process was painless, and the difference was immediately noticeable. Prior to the upgrade, having multiple programs open (Mail + Power Point + Safari +....) became increasingly sluggish and difficult. After the upgrade, I'm reminded of that fresh shiny new machine I unpacked back in 2010. Having used it over a week now, I can report that I've had no problems or unexpected glitches. If I do, I'll be sure to come back and report it. I'm extremely happy with the upgrade and recommend upgrading with this kit without reservation.

Pros: Cheap way to make your computer feel like new again.
Cons: None come to mind.

This kit is good if Apple recommends the following:
2 memory slots
Maximum memory: 8 GB or more
Specifications: Double Data Rate Small Outline Dual Inline Memory Module (DDR3) format
67.6mm x 30mm (1.18 inch)
2 GB or 4 GB
204-pin
PC3-12800 DDR3 1600 MHz type RAM
They also recommend that you fill both memory slots, and install equal sized memory modules in each slot. This kit does the job.

Size: 8 GB
Does your Mac only have 4GB of RAM? Upgrading the memory in your system is still one of the quickest and easiest ways to boost its performance. Buying it from a memory company instead of Apple will save you TONS of money. Though, unlike high performance desktop memory, there aren't as many distinguishing factors when considering which SODIMM to buy. Pretty much all the major manufacturers have similar stated performance specs, so why would you choose Corsair's Mac Memory Kit over the others?

PROS:
- Great price
- Tested at Apple's compatibility lab
- Proven reliability
- Excellent support
- Lifetime warranty

CONS:
- Hard to remove from packaging

INSTALL & MEMORY TEST
Installing the Corsair Mac Memory kit in a 15-inch MacBook Pro was quick and easy, though I struggled a little bit trying to remove the modules from the plastic packaging. The memory was immediately recognized by OS X and everything ran quickly and smoothly. Rember verified the memory size, type and speed. The Corsair kit also passed memory tests with flying colors. Check out the Rember screenshots I uploaded to Amazon.

RELIABILITY, VALUE & SUPPORT
The timing for the CMSA8GX3M2A1066C7 is 7-7-7-20, which is the same as the kits offered by the other manufacturers. So then why would you consider the Corsair memory kit over the others? The most obvious is price. The Corsair kit has a very competitive street price. Did you know that Apple charges $400 for an 8GB memory kit?!

What might be less obvious is that the Corsair kit has been tested at Apple's compatibility lab. This ensures that the memory you buy has actually been tested to work with Apple's products.
