I bought this as a DIY upgrade for my Mac Mini (stock Mid 2011, i5 @ 2.3GHz, 2 GB DDR3 RAM).

The RAM fits correctly and has noticeably improved the performance of my machine. Installation was a little tricky because of the confined working area inside the Mini's case. Eventually I got both sticks to fit into their slots and clipped down. Overall the install took less than five minutes -- nothing to sweat over. I booted into OS-X (Lion 10.7.1) without any issues and the 8 GB showed up in 'About This Mac' immediately.

I highly recommend this product, especially if you're a DIYer and want to save some money on your Mac Mini RAM upgrades.

Just installed this 8gb ram kit into a new 2011 MacBook Pro 15"; upgraded from the standard 4gb to 8gb with no compatibility problems. These module manufacturer labels matched the originals removed.
Writing this review just an hour after installation. So save the $100 from Apple upgrading your MacBook Pro ram and you still retained the 4gb as backup.

As usual, Crucial does not disappoint! I have never had a problem with any Crucial product. They are the best!

FYI, If you own a computer with one of the newest i3, i5, or i7 processors, you NEED extra RAM! The new Intel processors, while fast, are very RAM hungry! My previous iMac (a mid 2007 24" model with a 2.8Ghz Core2 Duo processor) only had 4GB of RAM (the max it takes), but did just fine. I never expected that a computer could ever possibly need more RAM than that.

But, after I loaded all the same programs onto my new 27" iMac with a 3.2Ghz i3 dual core processor (using Apple's migrate utility), I was shocked to find that it was running MUCH SLOWER than my old iMac, with the same amount of RAM installed as my old one (4GB)! I checked the Activity Monitor, and it turns out it was using up all the RAM (and then some) and then using virtual memory after that (you could always hear the internal hard drive spinning)

Fortunately, unlike the previous generation of iMacs, the new ones have 4 RAM slots instead of 2, and can take up to 16GB of RAM. Presently I am running mine with 12Gb (8GB from Crucial, added to the 4Gb that came from the factory) and WOW! What a difference! It is MUCH faster, and the hard drive isn't spinning all the time anymore!

According to the Activity Monitor my new iMac is actually using up 10 of those 12Gb right now, and I don't even have Photoshop open! I can't believe the new Macs use up so much RAM, but they sure seem to! It's not like I'm running any NASA mission control critical systems programs or anything! (Although I'd bet that 12GB of RAM is far more memory than was used by the ALL the computers at mission control during the first flight to the moon!

I have had crucial replacement RAMs on my other unibody Macbooks and they have never let me down so I trust the brand very well. I bought this for my new 13" 2011 2.3/i5 Macbook Pro. The allocated VRAM for the Intel HD 3000 GPU is now 512 MB, up from standard 384 MB. You can see it in the System Profiler. It does say in Apple.com that 2x2GB will yield 384 MB shared GPU RAM, but when upgraded to 2x4G, the shared memory also goes up to 512 MB, which is good. That's the only reason I bought to upgrade as I work on Lightroom 3 and Swift Publisher 2.

This is certainly not the brand or OEM RAM that came installed on my new Mac. Others have claimed otherwise. But it doesn't matter.

Wow. Just installed this on my 2011 MacBook Pro 15" 2.2 i7 (takes five minutes) and the difference is incredible. The performance before and after was so drastic for me I'm surprised Apple didn't just include 8GB from the start. Applications launch almost immediately now. This is what I expected when I upgraded to the Sandy Bridge line. Before this RAM upgrade, I was considering investing in an SSD to remedy the poor performance I was experiencing. I had no idea $50 of RAM could double the speed of my computer!

Like other reviewers have mentioned, whenever I had checked Activity Monitor I was running low on RAM. In addition, because the integrated Intel HD 3000 graphics card shares memory with the RAM (384MB), I found the computer almost always had to use the AMD Radeon 6750 1GB graphics card - a true power hog that will cut your battery life from 7 to 3 hours. Now that I have the additional RAM, the Intel card has 512MB of space to work with, and the computer is able to utilize it more (confirmed using iStat menus).

Now that RAM is so inexpensive, I would recommend paying the extra $5-10 or so for the Crucial brand. It's not worth taking any chances on cheap stuff.

Anyone who enjoys multitasking and browsing the internet should want this. Anyone who creates media on their computer NEEDS this.

Ordered two kits - one for my 2011 15" MBP Pro (Core i7 2.2GHz) and one for 2011 Mac Mini (Core i5 2.5GHz). Installation was painless and both sets have been working flawlessly so far. I didn't order from Amazon as a small number of customers reported kernel panic issues so I wasn't sure if this would work with mine. Went to Crucial and ordered two sets as they guarantee compatibility with my 2011 MBP Pro and Mini. For some reasons they have two different part numbers but when I received the modules they both have the same material code "CT2KT51264BC1339". Therefore all 4 pieces of 4GB modules are identical as far as I can tell.

Should have ordered from Amazon as the price is a bit lower.
