Crucial Technology 16GB kit (8GBx2), 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.

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 just installed this 16 GB upgrade(up from the std 8MB)in my late 2011 MBP. So far, it seems to be working fine, but I did have a little difficulty installing it. Removing the existing memory was tricky, but once I figured out how to hold both plastic retaining clips back on each side(takes 2 hands), the modules popped out ok, and the new ones installed pretty easy too(I thought). My main issue happened when I screwed the back cover on and powered my MBP up. It didn't recognize the new memory... it continued to show the old (2) 4MG modules(8 MB total). Next, I shut down completely and when I powered it up again, this time, it showed no memory in slot 1 and the new 8GB memory in slot 2. to see if I had a bad module, I opened the computer back up and switched the position of the 2 new 8GB modules. Then whenI powered it back up, I was pleased it recognized both of the new 8GB modules. I supose I didn't get one of them fully installed the first time. The only thing I noticed was that you can't just snap the new modules down into the slot where they go, but you need to push the modules further toward the connector pins to make sure they're in all the way

This memory is amazing! Crucial builds an amazing product that just seems to work better with Macs. I've used PNY, and it was fine, but I feel like Crucial runs smoother. This may all be in my head, but it seems great to me! Like many others I have a late 2011 15" MacBook Pro that technically states the maximum RAM is 8GB, but many sources and users have successfully installed and used 16GB with no issue. After going from 4GB to 8GB I saw a great improvement, but I would still often max out my memory using Photos, iMovie, and a few tabs in Safari. Figuring it was worth the shot I ordered the 16GB kit and installed it within minutes. I turned on my MacBook and was amazed at the speed things opened and ran. I believe OS X is designed to use as much RAM as is available, so going to the 16GB set was a great move. Programs and apps are very speedy and responsive and multitasking is no longer an issue. Boot time has improved substantially as well. Right before I installed the new memory I did a full restore back to factory of my MacBook and selectively recovered files and folders from Time Machine. That, along with new memory makes my three-and-a-half year old computer run like new.

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!

Replaced the original 2x2GB that were left after replacing the other 2GB's with 4GB's from Crucial when I bought my iMac from mid 2010. So I went from 12GB to 24GB. It is clearly making a difference. Next step? Adding a SSD for OS/Applications and if needed upgrade the 4GB's to 8GB's to use all 32GB supported. I am still very pleased with the iMac, would love to buy a new one with 5K display but why? It continues to be a very nice computer and foresee years of service for me. My conclusion: It's the easiest and most cost effective upgrade you can do and with current prices why wait? This pair was half the price and twice the memory compared for the 4GB's used when I bought the computer. As far as money/value I can say that I am still thrilled going from PC to Mac, haven't looked back and as you can see, the initial 'investment' is paying off with some tweaks to keep it up to date. It was still fine as it was but better now and can't wait for the SSD upgrade, to be coming soon. :-)

Upgraded my late 2011 15" MBP from 8GB to this 16GB RAM (together with an internal upgrade to SSD), and it's working well. RAM was easy to remove and easy to install — just have to get the angle right when slotting it in.

Works in my Apple as charm.

Our MacBook Pro 13" Late 2011 and 15" Early 2011 are more responsive than ever before... even with all our apps open at the same time. This is a really good upgrade.

La migliore RAM attualmente sul mercato. Utilizzata su MacBook Pro 13” Late 2011, funziona alla grande.
