Crucial CT2K8G3S160BM 16GB Kit (8GBx2) DDR3/DDR3L 1600 MT/s (PC3-12800) SODIMM 204-Pin Memory For Mac

I purchased the iMac 27" quad core I7 in mid march of 2014. Although, technically, Apple still classifies it as the "late 2013" model. I purchased this memory module kit after verifying its compatibility through the official Crucial website. This memory was verified by Crucial to work in late iMac 2013 all processors, Mac Mini late 2012, and all the recent Mac Books. The memory arrived in two days, very well packed and protected from static electricity. Ordered Sunday evening, delivered Tuesday. After verifying the correct product, I was able to install the memory module with my two fingers and a chopstick. (The chopstick was used to safely push the door open button without scratching my new toy). Basically, you lay the monitor face down, and remove the AC plug. Under the plug is a small (2mm by 4mm) button. Depress the button to unlatch the memory door cover. Remove the door and set it aside, remembering its orientation. There are two small "handles" that press to allow the module to swing out. There are arrows to show you the direction. Once it's out, you can gently but firmly press each of these memory modules into place. If you look at the picture, you will see Memory has a short and long side. The short side goes on the right. Gently press down firmly and equally on each corner at the same time and it will "pop" into place. Then swing the module back into the housing and replace the door. You may have to press a bit hard on the door, it's designed to fit tightly. Return the AC plug and upright your monitor and plug her back in. The entire process should take between 2 and 3 minutes. Hit your power button. The initial boot up the first time takes a bit longer than normal, so don't panic if it takes a minute or so before your screen flickers to life. To verify it has gone well, go to the very top left and press the apple in the corner to bring down the menu. Hit the "about this Mac", and it will bring up a box with the memory total and should also give a speed of 1600. This memory has been very stable. No glitches or heat issues. The speed of the computer has improved, particularity with booting up and processing pictures. Memory is the best, easiest, and cheapest upgrade for a computer. I have also noticed a small improvement accessing the ssd during some games. There is little difference in simple tasks such as emails or web browsing. Computers are already fast at that. However, using iPhoto has seen an improvement. Steam (an online game client) has also seen an improvement in speed. I am able to max all game settings without any frame loss or slow down. The iMac is set up for a voltage of 1.35 and this memory has a dual nature to run at a voltage of 1.35 or 1.5 This is convenient as it allows the smaller voltage to be used, cutting back on power consumption (although only pennies a day and realistically negligible) but also cuts back a little on heat production, which is the bane of all electronics. If you use your computer for any lengths of time, or push the processor hard, heat matters, and this could theoretically save wear and tear on your machine to keep it around longer. This is a good thing as apple products are not cheap... I did some research before purchasing. There are many brands of memory. Crucial, Corsair, Kingston, Transcedence, OWN, and the list goes on. Although Corsair seems to be the choice for most Intel pc computers, Crucial is the choice for Mac machines, by a pretty large margin. When doing your own research, be sure to be on Mac centric forums/boards. After such a positive experience with Crucial's customer service (about a 6 hour email response time to my compatibility question), the ease of install (credit to apple here though), performance boost, and no issues, I bought a second 16 gig kit to replace the four gig sticks that came with the machine. Don't be afraid to buy and install your own memory. Apple charges $600 to upgrade to 32 gigs of ram. You can purchase two of these kits for $300 (or under) and still have the 8 gigs you pulled from your machine to sell on eBay. (Save the memory stick package from your purchase for easy shipping packaging). One last thought. It seems the prices fluctuate a good bit. I bought my first kit on Amazon for 148$ about a week ago. Today, still on Amazon, I only paid 139$ for the same thing. Just something to keep in mind.

I overstretched my budget when I bought my MacBook Pro and ended up getting a unit with only 4GB of ram. Even though I really love using it, It really bothered me that it had so little ram. Every once in a while, whenever I was running multiple apps, the mouse would turn to a turning wheel and the app would freeze for a long time. Sometime for 5 minutes or more. This would usually happen while I was switching between apps and my first guess was - paging (or swapping, whatever you want to call it). My work also requires me to run windows every now and then and I was hesitant to install a VM on a machine that was so limited in ram. I googled "memory for mac" and the first match I had was from Crucial who also had a small app that runs on your system and tells you what the recommended memory for your system is. It recommended that I upgrade to 16G (even though apple says they support only up to 8G) and suggested two 8G dimms as follows: Brand: Crucial Module Type: SODIMM Module Size: 8GB Specs: DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V • 1024Meg x 64 • lead free • halogen free • for Mac Series: Crucial part number: CT3373653 I have worked before with Micron memory and I really liked it. The only problem was the price - they wanted $79+tax per dimm, free shipping, whereas Amazon only charge $139 for the pair. The technical specs are identical - but the two have different part numbers - and the one on the Amazon site cannot be found on the Crucial web site. I decided to go with the one from Amazon. Got the 2x8GB dimms (16G altogether) and they arrived in two days (prime). Installation took 3 minutes. Removed the cover and popped out the old ones - then pushed in the new ones. The only two things you need to worry about are: 1) Make sure that you turn off the laptop first (not hibernate) and remove the charger cord. 2) Beware of static electricity - I did that by keeping one hand on the laptop at all times, work slowly. Other reviewers warned about bad dimms - memory errors. It is true that some chips can be bad, but the talk about changing the pixels on your pictures is nonsense. Most systems detect those errors and halt (not that this is much better than corrupting your data), or fail during boot. Just to be on the safe side, I had my Mac run an exhaustive memory test when I booted (see here for details [...]). It took about an hour and came out clean. On bootup my Mac detected and used all 16 G. Performance is great. I think that I notice a slightly longer bootup from hibernate - and that's because it has to read 4x the amount it did before from disk during boot. Rotating wheel experience and freezing apps problems are gone. and the Windows VM is running great. I am really happy with this purchase.

Product link: Crucial 16GB Kit (8GBx2) DDR3/DDR3L 1600 MHz (PC3-12800) CL11 SODIMM 204-Pin 1.35V/1.5V Memory for Mac CT2K8G3S160BM ***** It was very simple to install it on my non-Retina MacBook Pro (Mid-2012, 13-inch). It showed up immediately after I rebooted and checked under About This Mac. Under Memory it will show 16GB in a 2x8GB configuration. You will get 1GB of video memory, but I think that was already there when I still had the original 4GB (FYI, it was made by Samsung). I love that everything is so smooth now, I rarely get the spinning beach ball of doom, and animations are now way faster. I also ran a memory test twice to find out the performance, and everything was good. I only have one small niggle with it, the serial number won't show up under the Memory section when you click System Report in About This Mac. My next step will be upgrading the hard disk into a SSD. So between $300-$400 for this memory kit and a SSD, you'll get better performance than if you bought a new PC. ***** Installation steps for those using a 2012 13" MacBook Pro: 1. Turn off the Mac, then turn it over. 2. Use a Philips #00 screwdriver to remove the screws. Keep in mind that only 3 are long ones, the rest are very short and tiny. The 3 go towards the hinge/lid, to the right if the hinge/lid is away from you. (basically when the writing on the bottom lid is right-side-up) 3. After removing the bottom lid, touch a metal part to discharge any static electricity. 4. Remove the first memory stick by pushing away the two levers until the first stick 'pops up' at a ~45º angle with a click sound. Gently remove it by holding the sides and pull it towards yourself with 2 fingers- never force anything. 5. Do the same with the second stick. It's more tricky than the first, but only because it's a bit recessed. 6. Insert one stick into the bottom slot first, gently push it in at a ~45º angle. Don't use force as that may bend the memory pins. 7. Push in the stick until almost all the gold pins are covered. Then push down until you hear a click again. Do the same with the second stick. 8. You may want to take this opportunity to clean the inside of the bottom lid and the fan of your MacBook Pro. It's not necessary and I didn't think to do this, but it'll make you feel better about your Mac. 9. Replace the bottom lid, and put back the screws. Again, the 3 long screws go towards the top right (when lid is away from you/writing on lid is right-side-up). Also keep in mind that the 3 long screws at 1 short one at the top must be screwed straight down, but the rest of the screws must be screwed in at a more slanted angle. 10. Boot up your Mac, and it boots up normally then everything is fine. Incorrectly-installed memory will usually cause your Mac to not boot up. 11. One more thing, I suggest you download the memtest utility from it's Wikipedia page. It's free, and installs in seconds. After installing, launch Terminal in single-user mode. This can be done by pressing Command+S when your hear the Apple boot sound; then pressing Command+Spacebar to open Spotlight. Type in Terminal and clicking at the result that says Applications. 12. Once Terminal starts and you see your Mac username, type in "memtest all 2" without quotes. This will test the memory twice, which is usually enough to spot any problems. In my experience, this took just below 2 hours. You may want run it multiple times (change the number from 2 to something like 4/5), so do this before you go to bed or something. 13. If it says all ok under every test, rest easy. If not, try to contact Amazon or Crucial. Don't go to Apple or your OEM, this is not their fault if anything is wrong.

My Macbook Pro has had 8GB of RAM for far too long. I finally purchased this 16GB of RAM and I'm so glad I did. I have a late 2011 15" Macbook Pro. For a computer, it's now considered pretty old. It came with 4GB of RAM which I immediately upgraded to 8GB. I thought for awhile that those 8GBs were enough. Boy was I wrong. After finally realizing that a number of my slow downs on my laptop were due to not enough RAM for the applications I was using, I started to look into buying more RAM. 16GB was the obvious choice. Now Apple technically says that my late 2011 Macbook Pro can only use 8GB of RAM and only RAM at 1333mhz. I read various places online, including reviews here for this product, that this wasn't true. I read that my Macbook Pro was completely capable of using 16GB of RAM and that even 1600mhz RAM would work. I decide to trust it and give it a shot. I bought this RAM and installed it simply and quickly with no issues. I ran the Apple hardware test before fully booting up my laptop and all tests came back great with no issues. After I fully booted it back up, I was very happy to see that the Macbook Pro reads the full new RAM at 16GB and 1600mhz. My laptop has been running great ever since installing this new RAM and it's been running much faster too. I keep multiple applications open, including 20+ tabs open in my web browser and I've had no slow downs at all. This has been a great upgrade and I'd recommend it to anyone looking to increase the RAM in their laptop.

I probably like most people have the mid-2012 macbook pro. I bought this January 14th and chose it over the Retina Display equipped MacBooks because they were cheaper, but also because they are still upgradeable. This was the stock 500GB Hard Drive, 4 GB of RAM version if you don't know the Macbook's specs by heart. I have since upgraded mine to a SSD for fast boot up and application launches, and then along came Yosemite. On Mavericks I had an average of 2GB free give or take. That all went away with Yosemite. I had roughly 600MB free at all times. This of course always gave me the spinning wheel, and would perform slowly when trying to multitask. I was looking at purchasing RAM and decided to go big or go home, and purchased the 16GB kit over lets say an 8GB. I'm very glad I did so. At the time oft his writing, I purchased the 16GB kit for $130. Perfect price compared to in store or other online retailers. It was the easiest thing to do in terms of installation. I used OWC's tutorials on youtube to help me step by step as I didn't want to forget or miss a step even though I knew how to already perform this task. It took me all but 3 minutes to take out the old RAM, and replace it with Crucial's RAM sticks. Trust me, my brother or mother could've done this. I think 8GB would be perfect if you're on Yosemite but don't do much. you'll have about 4GB or less left while performing normal tasks. I myself run Excel, iMessage, Mail, Skype, and multiple windows in Safari on the web. It FLIES through tasks, I do not miss the spinning wheel at all. Don't wait any longer to upgrade your memory if you're still running a 4GB equipped Macbook. You will thank yourself later. And if it is in your budget -- purchase an SSD and replace em both at the same time. It's totally worth it. ---- Side Note: You will need tools for this and I HIGHLY recommend OWC's kit, it will come with everything you will ever need to replace the RAM, and SSD should you choose to do so.

Its exactly what I needed. I got my new MBP (i7 processor, 2.9 ghz, 1TB HD, 13 inch 8g stock ram) a couple months ago and decided to also invest in protective casings, screen protector, keyboard cover, the list goes on because its always been my dream to get one and I figured since I had the means now I'm going all out. I'm an above average user; I use Parallels; iMovie; Pages; Safari; Logic Pro X, Audition, and a few other programs on a daily basis. I noticed that when I was running Parallels my system would slow down quite noticeably often crashing programs I was using on my VM making my projects more difficult. I did quite a bit of browsing before I made a decision on if I should buy this and if I could install it. Everyone asks if 16g is "overkill". This was kind of a concern because I didn't want to spend 160$ (with shipping) on something I'd just have to return. After watching a couple of youtube tutorial videos on switching out ram and a run to Home Depot for the correct screwdriver, I can say I am glad I made this purchase. When I'm not running my work programs, I usually am just browsing the web, maybe doing some downloading and streaming netflix... average, everyday user type of stuff. If you use your MacBook Pro for work and you're using a few apps on the reg or a VM this is probably worth the investment. To help you make your choice, if you're still questioning it just use Activity Monitor to figure out if 16 GB would be appropriate for what you use your machine for. If you use your laptop just for web browsing and email and such, 8 gigs will probably work just fine for you. Even though I have this installed, when I'm not using memory intensive apps and such, my MBP uses about 2-4 GB of ram. But I feel better knowing that my system won't get overloaded and become stale or start freezing while I'm working on important things. PS Make sure you get a 0 and 00 Phillips Head screwdriver (only like 2$ at Home Depot) to unscrew. Had to do some research to figure out the right answer. Also you may have to turn kind of slow a few times when unscrewing to get the screws coming out. Just be careful when you do it and try not to slip as to have scratches on the bottom of your nice investment . The only reason I'm giving this 4 stars is because it's a little pricey (maybe not for some people but it seems a little pricey for what it actually does). Happy Shopping!

My late 2012 Macbook Pro is working better than it did the day I bought it and I am blown away! WHY did I wait this long to upgrade?!?! I was rocking 4gb and struggling to run more than two applications at one time and if I had photoshop pulled up- forget it. Or the dreaded Photos! Oh I will not be missing those days of slow loads and forever spinning rainbows. I was unsure about updating to 16gb since Apple said my system can only support up to 8gb but thanks to the wonderful customer service of Crucial, I was told that there was an update a couple of years back for my computer that made it okay to run 16gb. I am not super tech-y but I can figure things out pretty well so as long as you can follow some very easy directions- you'll be able to upgrade your laptop with ease. I will say I had to order this package twice. The first time, only one of the 8gb sticks worked. I was running off of one 8gb stick until the new sticks came in and it worked completely fine. But I am glad I chose 16! Photoshop, Lightroom, Photos, Chrome, Mail, I run it all just because I can! (but really I run them all together for convenience while I work on multiple things) So yeah. After calling customer service inquiring about why my computer wasn't accepting the upgrade (the first package) they had me run each stick separately- figured out one stick was bad- Amazon issued me a new order, got the new order, installed both sticks separately to ensure they both work-they did- installed them both- and viola. Magic. I have fallen in love with my computer all over again and my husband no longer yells at it any time he tries to use it. He's a PC gamer guy and hated my slow 4gb Mac. 6 Years later, it is now an updated magic mac. Other notes: I used the scanner on the Crucial website to determine what kit to buy. It suggested which kits would be the best fit and I chose this one because it was the largest/fastest. Next upgrade I'll consider is switching to a solid state but my little lappy is running mighty fine. I recommend!

Why 5 stars: First and foremost it works, second, value... I did a little price shopping and considering shipping Amazon has a competitive price. I love the no hassle return policy and was worried if I had issue with this memory I didn't want to pay to return it. What I love/hate: First I love that it just worked. After installing the memory I've been stress testing four of these 8GB sticks in my new (late 2012) iMac for the last 24 hours. I'm using Aperture with images from a canon 5D Miii (22 MP) to load up the memory. So far so good, no lock ups or forced restarts. I will post an update if this changes. There is a slight but noticeable speed increase in operation of the iMac now that I've upgraded the RAM from the stock 8GB. I'm very pleased with the speed bump and notice fewer lags when the system has to dump it's cache'd images in order to load new ones - which with large images is only a few images at a time. What I hate is that I had to watch a you tube on how to access the memory - no reduction in points for the memory but pushing a little button and inserting memory shouldn't include second guessing how much force you're applying. Who should buy: I've noticed no matter what I throw at the iMac it will only leave about 12GBs in cache. Which leads me to believe 16GB is possibly the point of diminishing return. If you are concerned over how much $$$ to spend on the upgrade try getting only one kit and upgrading to 24GB with the stock 2x4GB sticks, or perhaps order an 8GB kit to make your total 16 GB. As for me, I just wanted to max it out in hopes Apple will update the OS enabling the use of all available memory.

Mon Macbook pro 15" début 2011, modèle A1286 chauffait beaucoup et était parfois assez lent. Il a même planté 2 fois à cause d'une panique du noyau. J'ai décidé de changer la mémoire vive avec 2 barrettes de 8 Go DDR3 1600 SODIMM Crucial (disque dur SSD 1 To Samsung déjà installé) et en ai profité pour nettoyer toute la poussière et les minons en dévissant simplement les 2 ventilateurs et en passant un petit coup d'aspirateur (avec embout adapté), opération que j'ai pu effectuer grâce au Mako Driver Kit 64 de iFixit (embout de tournevis spéciaux adaptés notebook, tablettes et smartphones y.c. Apple) super pratique et disponible également sur Amazon. Bref, on voit sur les photos, ça marche vraiment (malgré que Apple dise officiellement que l'upgrade max est 8 Go pour ce modèle Macbook). L'opération est vraiment simple et rapide à effectuer, il y a des tutos sur internet, l'ordinateur ne chauffe et ne ventile plus intensément, je suis vraiment content pour la partie technique. Cependant, j'émets une réserve sur le prix pratiqué car cela m'a coûté 141,33€ alors que quelques jours après l'article est descendu à 129,90€ et qu'il y a même une autre page Amazon pour le même produit à seulement 114.90€ - Crucial CT2KIT102464BF160B 16Go Kit (8Gox2) (DDR3L, 1600 MT/s, PC3L-12800, SODIMM, 204-Pin) Mémoire - qu'on m'explique juste pourquoi j'ai payé presque 30€ de + 1 semaine avant sur le même site marchand ?

Dopo aver acquistato un SSD della CRUCIAL per il S.O. del mio iMac, che và splendidamente, non ho esitato ad acquistare anche l'espansione di memoria e dare una spinta in più ad una macchina del 2013 che và ottimamente. Il sito della CRUCIAL è molto dettagliato e guida alla scelta della memoria necessaria per la propria macchina. Il tempo di installazione è di 10 min. Ho preferito investire sul nome per evitare problemi di cattivo funzionamento. Ad installazione effettuata, le app si aprono visibilmente più veloci. L'apgrade della memoria, come è noto, migliora la gestione delle app, più che la velocità complessiva della macchina quindi consiglio prima di fare l'upgrade dell'HDD con un SSD e poi della RAM. Consiglio l'aquito a tutti.

Works great, my 'late 2012' mac mini is running much faster now; no more lagging. It is simple to install yourself but check 'About this mac' after to make sure both are working ok. My first attempt at installing resulting in only one connecting properly so it said only 8GB. The computer was still running ok even though it was only using one slot, but using only one slot is NOT recommended. I shut it down, disconnected all cables again and reinstalled them again and thankfully I got them in the slot properly on the second attempt. It now reads 16GB (8 GB each slot) and works great. The 'Activity' monitor now reads around 5GB of (ram) memory being used so its easy to see that when I only had 4 GB of ram, it was a problem. You have to be careful, when removing the old ones and installing the new ones, they are in snug (not loose) so you will need to use just a little pressure to remove the old ones and to push the new ones back in place but be very careful not to bend or break anything. Its worth checking out a 'how to' youtube video. 'Prime' took 10 days to deliver to St.John's, NL, so if you want it faster, you might want to pay for shipping if you are ordering from this end of Canada. Recommended!

They work perfectly! Great packaging and simple installation!

it works very well
