From the Manufacturer

Crucial Memory for Mac

Compatibility for Mac systems.
Engineered to be compatible with your Apple system, Crucial Memory for Mac takes the guesswork out of a memory upgrade. Since Apple systems often have very specific memory requirements, including particular component densities, speeds, and SPD programming specifications, it’s important to buy your memory from people who know Apple computers inside and out. With over a decade of experience manufacturing and developing memory for Apple systems, we make it easy to find memory that’s been designed specifically for your system.

Reliability for Mac systems.
If you’re an Apple computer user, you probably expect intuitive, reliable performance from your system. We think memory should work the same way, too. For each module we manufacture, we send it through a rigorous testing process to ensure that you’re getting a reliable, high-performance memory solution. Every module that leaves our doors has been extensively tested at the component level for voltage and temperature resistances, signal integrity, and software compatibility. Even better, our modules are lead and halogen-free.*

Support for Mac systems.
Unsure how to install memory or have an important question about your Apple system? Let our team of experts help! With a tech-savvy team that’s well-versed in Apple systems, we’ll provide the technical support you need—no matter how old your Mac computer gets. From phone support, videos, FAQ articles, and do-it-yourself guides, we’ve got the resources you need to keep your system up to speed.

Crucial—quality you can depend on.
Crucial is a trusted name when it comes to DRAM, and that’s no coincidence. As a brand of Micron, one of the largest manufacturers of DRAM in the world, we work with our engineers to design, refine, test, manufacture, and support our extensive line of memory modules. With a product portfolio that includes more than 250,000 different DRAM upgrades for more than 50,000 systems, we’ve got one specifically designed for your Mac system. For more than a decade we’ve kept Mac computer owners happy with high-performance memory and outstanding customer service.

Size: 16GB KIT (8GBx2) Verified Purchase
I'm pleased to report that indeed, 16 GB of RAM does work correctly in the 2011 MacBook Pro, and, it is even recognized at it's full speed: 1600 MHz. All the functions of the MacBook Pro work correctly, including waking from sleep. Having this much RAM may seem like too much, but it is great if one uses several programs at a time or works with large datasets or image files.

Installing this RAM is relatively easy. There are instructions in the MacBook Pro's User Manual and online at Apple Support; even nicer instructions with step-by-step pictures can be found at sites like ifixit. Basically all one has to do is remove the screws on the bottom of the case, being careful to keep track of location of three of the screws that are longer than the rest.

As for quality of the Crucial RAM, the actual memory chips are by Micron, a respected manufacturer that supplies Crucial with most of the RAM they sell. After installing the RAM, I used the Apple Hardware Test (AHT) to verify that this RAM worked as it should in my MacBook Pro. I followed up on the AHT by running Memtest overnight to test the RAM - it passed with flying colors!

You may wonder how come it's ok to use 16 GB of RAM when Apple specified a maximum of 8 GB of DDR3 1333 MHz RAM for the 2011 series of MacBook Pro laptops? As you can see if you peruse the web, there are many, many reports of users installing and successfully using a maximum of 16 GB of RAM in the 2011 MacBook Pro laptops. The reason why Apple specified only 8GB as a maximum is that when these MacBook Pros were released, RAM modules denser than 4GB were not available in the appropriate sized SO-DIMM. With the subsequent improvement in RAM manufacturing technology, it's now possible to use up to 16 GB of RAM in the 2011 MacBook Pros.

If you go to the crucial website and have them scan your MacBook, they'll recommend you a CT kit with a serial number that doesn't match this one. As alarming as that might seem, the crucial website FAQ's indicate that the serial numbers may vary for warehouse storage and distribution, and that you should pay attention to the listed specs instead.

Anyways, the installation was surprisingly easy. It consists of a simple unscrewing and removal of the back panel followed by popping the old ram sticks out and popping the new sticks in that even an tech-unsavvy person like me could perform. I found the RAM replacement video guide on crucial's site helpful, since the guy points out a few safety considerations like static discharge and the numbers and placements of screws.

Once installed, I immediately noticed the difference in the upgrade. Applications are opening much more rapidly than they used to, and Parallels for Mac is running in seamless clarity. I highly recommend this upgrade to other MacBook Pro users running on 4 GB of RAM or less.

I initially installed this memory in the already-open slots 1 and 3 (the factory RAM was in slots 2 and 4) and got 3 beeping sounds and no bootup. After following the advice of another reviewer here, I turned it back off, opened the memory compartment back up, and swapped the positions of the factory RAM and the Crucial RAM so it went like this:

Slot 1: 4GB Apple RAM (Top slot if iMac is upright)
Slot 2: 8GB Crucial RAM
Slot 3: 4GB Apple RAM
Slot 4: 8GB Crucial RAM (Bottom slot if iMac is upright)

That worked fine and I now have 24GB of RAM installed on the Late 2012 27" iMac.

Tip 1: the Crucial RAM is a tight fit in the memory slots. To get them back out to swap their positions, I first had to remove the Apple RAM so that I could get a better grip on the Crucial RAM.

Tip 2: I had difficulty getting the memory access panel off of the iMac because my finger wasn't going far enough in to depress the button all the way. I used a small key (a screwdriver would work too) to push the button in all the way to get the access panel to pop open.

I bought this kit to upgrade a late 2012 Mac Mini. Worked flawlessly, as I would expect a Crucial product to do. Amazon had this for less than buying direct from Crucial, free shipping, and fast delivery. What's not to like?

I was hesitant to buy these from amazon because the product model Number didn't match what crucials website said I needed when I chose my system on their product finder system. Later I was told by crucial that they use the same exact modules but give different product numbers to them depending on what system you input into their product finder. So long story short, I bought them and installed them I. My brand new imac.

My system booted on the first try and all 32gb worth registered in the system without any problems. This is an excellent deal! Apple wanted to charge $600 to go from 8gb to 32gb. I spent less than $300 to do the same with these modules and I got to keep the original 8gb of ram that came with my imac to use I. A different system!

One more thing!
Installing these isn't for the faint of heart! You hand to align them in the slots just right and push them I. Pretty hard to fully seat them. They may seem like they don't want to fit or are too big, but trust me, they fit and work just fine. Just push on then hard and they will go in.
