CORSAIR 16GB (2 x 8GB) DDR3 1333 (PC3 10600) Memory for Apple Model CMSA16GX3M2A1333C9

Pros: Inexpensive, had a rebate, lifetime warranty

Cons: Intermittent failure

Other Thoughts: At first I started getting a frozen cursor when playing games. Then a few random reboots. Finally came home one day and my Macbook had garbled video and was doing three beeps, pause, three beeps...

I researched and found out it was likely bad RAM. Ran the Apple Hardware Test and basic and complete modes - same result - bad memory. Specifically 4MEM/9/40000000: 0x846b2198

I've requested an express replacement from Corsair - we'll see if the replacements are any good. I never ran a test when I first installed the RAM - I recommend you do so when you put them in.

Pros: Easy to install. Greatly increased the responsiveness of my laptop.

Cons: None that I've observed.

Other Thoughts: I'm a web developer and I have been using a base-model mid-2012 13" Macbook pro as my primary work machine. It was working fine but between switching from Textmate to Sublime Text 2 and a project that had me spending more time in Photoshop, it needed a bit of a boost. Everything is markedly faster now, including loading large PSD files.

Apple says this particular machine will take up to 8 Gigs of RAM, but I took a chance and I'm happy to report that the OS is recognizing all 16 Gigs and the RAM has functioned flawlessly. This upgrade turns one of Apple's least expensive laptops into a seriously productive machine.

Pros: Perfect compatibility with Mac Mini 2011. Upgraded my mini to 16GB. Additionally, with a Samsung 840 Pro 256GB SSD from Newegg, this makes my original $600 mini powerful enough to easily run 12GB Fusion virtual machines. The W7x64 Windows Experience Index inside the VM (aside from graphics) is 7.7 to 7.9 for both RAM and disk. Wow

Cons: None.

Other Thoughts: Researched this and I believe this is the most popular and compatible RAM for upgrading the Mac Mini 2011. Definitely the price is awesome, too.

Pros: Easy to install.

Cons: None

Pros: Price, Speed. 16 gb.

Cons: Only compatible with mid 2011 and newer models.

Pros: Passed memtest, huge bang for the buck.
2011 MacBook Pro had no issues recognizing the all 16GB of memory.

Cons: Pachaging seemed a bit on the cheesy side, but I can overlook that for the price.

Other Thoughts: This laptop originally came with 4GB of memory, I upgraded it last year to 8GB, and its gotten so cheap now I figured I should do it now if I planned on keeping the machine for another 2 years or so.

Seems like a great value, easy upgrade for your machine.

Pros: Fast. Super fast!

Cons: None

Other Thoughts: I installed these into my Late-2011 15" MacBook Pro without any problem. While Apple doesn't officially support 16GB on this model, the hardware does work with 16GB of RAM. No problems at all and the MBP is running Skyrim like a dream!

Pros: No problems at all really sped up my mid 2011 imac 27in i left the 4 gigs that came with it in and running 20gigs now!
apple wanted 300 for the same ram!

Cons: none

Pros: It registers as 16gb on my late 2011 Macbook Pro.

Cons: It worked for about one week. Afterwards it started to cause my computer to freeze. I have used gskill 2x4gb ram without any issues. When I put the oem or gskill ram back in, its smooth sailing.. Not only does it freeze.. it also causes the rainbow ball of death.

Other Thoughts: I wish it worked...

Pros: - Great price
- Fast memory
- High capacity
- Macbook Pro is a lot faster now

Cons: - Did not arrive in an antistatic bag (surprising)
- memory tests will take a LONG time

Other Thoughts: Four gigs wasn't enough, I run Photoshop, Illustrator, Dreamweaver plus Firefox with a ton of tabs and flash. Sick of the spinning wheel cursor so I went for sixteen gigs, which are going to last me a long time.

I was initially cautious after reading some reviews that the memory arrived DOA. I was also unsure if this was *really* going to work in my Macbook Pro (Late 2011). Also it wasn't packed in an antistatic bag which left me a little worried.

Memory installation was a cinch and everything turned out fine. All you need is a tiny Philips screwdriver to open your laptop. This is the correct memory for most Macbooks produced in the last year or so (1333 mhz PC3 10600.)

I didn't run the Apple Hardware Test on my ram (hold D on reboot) as I never get any memory errors on boot.
