Crucial Technology 8GB, 204-pin SODIMM, DDR3 PC3-10600,

I got this to upgrade my late 2011 15" MBP (2.2g i7). I originally had 4GB, but it wasn't enough when I'm working on a lot of things have multiple Chrome tabs open, Word, Acrobat Pro, Photoshop, Illustrator, Spotify, and Evernote occasionally. I still had Mountain Lion and wanted to upgrade to Mavericks. Plus, a friend gave me ProTools 10 since I wanted to experiment with recording and editing some music. So, I definitely could use a memory upgrade... Apple said that that my machine can only only be upgraded up to 8GB, until I read from others that a 16GB works. Then I went to the Crucial site, ran their memory advisor, and this kit came up on top of the result. Before purchasing, I've read some opinions that the difference between a 16GB and an 8GB is hardly noticeable. However, since I plan on eventually replacing my HD with a SSD, and just for about $60 more, I just went for this 16GB kit. Much cheaper and less hassle in the long run if you plan on upgrading to 16GB later. I don't know about you, but I prefer to have same size ram for each of the slots, which is also recommended anyway... And did I mention it was SUPER easy to install? Just follow the instructions on the Apple site and make sure everything's properly inserted as there's kind of a trick to it (you'll hear a click/snap that tells you it's in). I guess my only advice is to be gentle from when you open the case to removing the old memory, especially on the first time. There are times when it feels like something won't budge. Instead of going full force, just gradually increase pressure and you might have to wiggle some stuff a bit. It also helps to have the right tools, especially if you don't want to void your warranty... So, with the 16GB memory and a clean install of OS X Mavericks, my MBP runs 3/4 times faster. Adobe CS apps load within 3 seconds and there's no lag when switching in between apps. I've had the memory kit installed for about 3 months now, and I never had any problems, nor have my machine get really loud (and sometimes hot) when running intensive applications. I'm a happy panda so far!

I am a music producer, and recently started to work on a project where I have to sync and edit music with video (post-production). I have a mid 2011 iMac that came with 4GB of factory RAM, and it has been working perfectly trough these years. The problem raised when I had to load video sessions on Pro Tools 12, because it says 8GB minimum requirements for video. Still, my iMac handled the sessions, but I got constant problems when I tried to add plugins or even import the video files (and don't get me started with the final export). So I decided to upgrade the RAM. I got this kit, I installed the RAM in approximately 10 minutes and now I have a whooping 20GB of RAM. Now, every video session runs like a dream, and I can put as many plugins as I want. I've been checking the Activity Monitor constantly and the kernel keeps a lot of ram in use, so now I understand why I had RAM problems before. (And that Avid Application manager is a RAM hoarder too, poor design there from AVID). But now I have only 7GB used constantly, and have free RAM whenever I need to load a session, even if I have a whole orchestra of AAX, plugins galore and everything I can ever need. Overall, they work perfectly and have improved my workflow in a major way. Would absolutely recommend this upgrade to any iMac owner, specially when it is this cheap compared to a factory RAM upgrade and the installation process is so straightforward.

Jumping from the factory original skimpy 4GB of RAM memory all the way up to 32GB of memory with two of these 2X8GB Crucial memory kits was incredibly beneficial for my 27" mid-2011 iMac which I use many hours each and every day and rely upon for both work and fun. I did the upgrade several weeks ago and have never looked back. Now, I have no more pinwheels or spinning beach balls. No more cherry red moving blocks in the "memory" section of Activity Monitor -- just a skinny green line near the bottom of the box. No more buffering for videos. No more nagging error messages with browsers. No more required "force quit" actions. No more unwanted restarts. No more waiting and waiting and waiting for files to load. No more sluggish Time Machine backups. No more annoying crashes or freezes. I can (and do) use two different memory-hungry browsers at the same time with more than 20+ tabs open in each one with absolutely no diminution in performance and huge chunks of memory available to spare. And opening three or four other memory-heavy programs at the same time the browsers are open makes no difference at all to the operation of the iMac. This was an easy fix and an easy task to complete for someone who is usually not comfortable doing these kinds of things with electronic devices. The process takes about five minutes and is carefully explained in full detail in manufacturer's pages and in helpful YouTube videos available everywhere. Everything worked exactly as prescribed without any glitches or unexpected problems. So, again, "do it now" if you are having problems with your computer and have only the minimum memory supplied by the manufacturer. That's not enough for today's programs, apps and operating systems, and this fix really works.

I watched the performance of my MacBook Pro 13 in (late 2011) degrade slowly over a period of time. It seems every time the OS was upgraded, the performance went down.. I'm currently on Sierra .. and after a year or so, I had enough.. I looked at the Activity Monitor to see what was happening and noticed that the memory swap used was relatively high. I knew at that point it was time to upgrade the memory. I realized that when we originally bought the MacBook, 4Gb was sufficient, but over time with the OS upgrades, new software added, it could no longer handle it. I checked the compatibility online to make sure I got the right one, and then placed an order through Amazon. I was excited when it came and quickly shut down my laptop to install the RAM. Installation was very easy and took less than a minute (you will need a small phillips screwdriver to remove the panel of the laptop, to expose the motherboard). Turned it back on, and got the dreaded three beeps. I went back, removed the RAM, and reinserted.. and tried again.. and again, the three beeps... Removed the new RAM, and re-inserted the old memory and everything was fine. I checked the package and model numbers, and everything was correct. At that point, I thought to myself.. there is something wrong. I returned it and re-ordered a new set. Repeated the steps, and this time, upon startup, no beeps! Everything seemed more responsive, and applications opened quickly. I check the Activity Monitor, and looked at the memory swap - a big fat Zero!!! I'll have to remind myself to check the Activity Monitor over time periodically. If memory usage ever creeps up to 7 Gb, it will be time to upgrade to 16 Gb.

Hi , 13" MBP early 2011 . Just received this yesterday and installed them . I have so much extra memory to use ( great ) . Installation was easy , And my macbook pro recognized the memory right away w/no problem . It is working faster and better no lag time . When i contacted Crucial they said ( if the computer does not recognize the upgrade when you start your computer wait then when your computer starts wait until you here a chime then press , command + option + p + r , All 4 At the same time . Then when you hear the 2nd chime let the keys go and the computer should recognize the upgraded new memory ) . Check w/them just to be sure . I had no such problem it recognized it right away . And when i open iPhoto i used to have to wait for the pic to upload no more their there . I went from 4gb to 16gb of memory and now i have on the average 75% of the 16gb memory available . I'll keep you informed . Thanks. I now have 6 tabs open and i'm at 61% memory available on ( 16gb ) , I could have never done that w/just 4gb of memory . Keeping you informed . Thanks . ( 8-6-16 ) Still no problem i have noticed that the more memory that you have , The more that your app's and other things try to use the memory . That's why i went with 16gb over 8gb upgrade , I'm glad i did ( 8gb upgrade $45 - 16gb upgrade $60 , $15 more for twice the memory . In my option a no brainer . ) Thanks .

I began taking computer classes at my local community college, and I was suddenly faced with downloading huge programs and running them simultaneously on my 2011 Macbook. Yes, my early model 2011 laptop that is nearly 9 years old at this point. Needless to say that it was running SLOW. Even before downloading and running these new programs my laptop was crawling along. I was frustrated and very seriously considering purchasing a brand new Macbook for upwards of $2000. But my professor suggested simply replacing the RAM in my old computer. I never, ever thought that such an easy and simple solution would breath new life into my laptop, but I can honestly say that my laptop runs like brand new! I was incredibly nervous to open up my macbook, but installing the RAM was so easy and simple. I did a LOT of research before purchasing my RAM, and I found that Crucial was a highly recommended brand. While Apple is an American company, most of the parts that make up their computers are foreign made, so don't be too worried that your RAM is made in China - they all are. I replaced the RAM over 2 months ago, and my computer has had absolutely no issues since. It runs as well, if not better, than a brand new Macbook - I believe that brand new 2017 Macbooks only have 8GB of RAM, so my old lady actually runs faster. I can now run tons of programs at once with no issues whatsoever. I cannot recommend this RAM enough!

Recently my MacBook Pro 17" had an issue with the Processor that caused the video card to burn out. It seems that Apple had a known issue with the Radeon Chips causing problems and they fixed it for me at no charge. However, they did do a DX check in the repair shop and it seems that one or two of my RAM sticks were having issues. AND - much to my dismay, they made the choice of replacing my 16gb of RAM with FOUR gb of RAM!!! The 'genius bar worker' even told me that they put in a new kind of RAM, and that my machine would be up and running like a new MacBook Pro. NOPE that was not the case! They replaced 16gb of 1333htz DDR3 RAM - with the EXACT specs of mine with only 4gb of the exact RAM but in a different non known brand name (I was told in the store that it was Apple Ram memory) there was no such thing in my machine. The choice that I now had for my slow as molasses machine was to order new NAME BRAND memory. And, Crucial is the ONLY name as far as we're concerned in our home. (the RAM that had a couple of sections blow out, that was in my machine was NOT crucial, it was also a generic brand that I got when I first started to upgrade my machine, and at that time, NO Crucial was available to me as there was a wait list, and they had no idea how long it would take. And in their defense, it did last for almost 4 years! But, Crucial is STILL our go to name brand RAM choice, and I am super pleased that they have dropped prices, and upped manufacturing to assure that there is no back ups for RAM needs. My MacBook Pro is up and running like a fantastic NEW machine out of the box - I know that I now have at least four or five years on my rebuilt machine - and that makes me a happy person for sure!

Just installed 16GB of DDR3L 1333 on my early 2011 Macbook Pro. I'm not very tech-savvy, however installing this was quite easy. The reason for purchasing this item(s) was because I finally upgraded to El Capitan OS X, which slowed down my cpu significantly. Pages, Chrome, and Word took much longer to load after this software update. I read that it was possible to do 16GB instead of simply 8GB (the latter being Apple's recommended Max), and so I gave it a try. This is Day 2 with the new, updated hardware. My computer is running FAST and SMOOTH -- no delay in opening my programs, even if opening multiple ones quickly (this would've killed my system a few days ago it seems). Hence, my review. This is working very well and I hope it continues to do so. My Mac is recognizing 16GB under my system preferences. I'm told they don't "support" 16GB, although I don't know exactly what that means. Also, I read I'm supposed to "test" my new hardware. I don't really know how crucial that is or how to do it. So, please note that I have not ran any specs on this (that is, "hardware tests") to see if everything is working properly before writing this review. Things just happen to be going well at this point, so I'm rejoicing enough to type this out. Bless you all.
