## Questions & Answers

**Q: Can i install this memory on my imac 27 inch mid 2010 with Intel Core i5?**
A: And it did not work on my iMac 27 inch mid 2010 3.6 GHz with i5 ver 11,3. Called Crucial and they wanted to tell me I had 3.2GHz i3. Further told me that the only way I could get to 16GB of memory was to install 4 x 4GB chips. Plenty of information out there that states this is not true and regarding my machine, I know I purchased a 3.6 GHz i5 and the Mac self reports this, so I'm not confident in Crucial customer support and unfortunately am out the expense of this "upgrade."

**Q: Can Someone confirm if this works on MacBook Pro (13-inch, Early 2011). I currently have 4GB RAM. Thank you. Guru**
A: I have an 13 inch MacBook Pro (Early 2011), it worked and the difference is really noticeable from 4GB to 8GB.

**Q: If my mid 2011 imac 21.5 inch originally has 4gb of ram split into 2 sticks. Can i buy this 8gb kit and add it to the existing 4gb?**
A: I have a mid 2011 imac 27" - clearly states everywhere that the max i am to use is 16GB - 4GB in each of the 4 available slots.  In desperation from my computer freezing almost every few minutes using the internet I took out the 2 4GB I had in 2 of the slots and replaced them with these 8GB - I now have 24GB available.  I can now surf the internet again with more than one window open.

**Q: Will this work with mid 2011 iMac?**
A: The mid 2011 iMac uses 1333Mhz ram.  usually the 1600Mhz ram will down speed and work without any issues, sometimes there are hiccups.  You would be better off getting the 1333Mhz ram.

    Works in iMac (late 2013) - but watch for the initial slow startup.
  

*by A***R on Reviewed in the United Kingdom on 20 April 2014*

I bought two lots of these to beef up my late 2013 27inch iMac i7 to 32GB. They worked perfectly after waiting for the hidden POST to complete. When you first plug in an iMac it goes through a hardware test cycle, keeping a record of any changes. When adding 32GB it took about two minutes for the iMac to check the RAM before it would turn on. I have seem many people complain their iMac did not work after upgrading the RAM; it was more likely they did not patiently wait for the system to finish updating its spec details. So here is the sequence whenever you change RAM on an iMac, even if downgrading to use the original RAM!1. Disconnect power.2. Open door to memory slots and pull down the memory holder as shown in the iMac manuals.3. Remove existing RAM, carefully noting which slots are populated AND the module orientation.4. Add new RAM to either the same slots OR all slots if you are adding four modules, carefully checking each module is properly oriented and fully seated. Unlike PC's, iMac memory slots are somewhat 'sloppy' - don't expect a satisfying click.5. Push the memory holder back in to place. If it won't go back properly, check the modules are correctly oriented and fully seated. 6. Close door to memory slots.7. Plug in iMac and make sure mains power is on, but *DO NOT* press the power button.8. Go make a cup of tea. (Important)9. Come back and click the power button.10. Bong......In future the iMac should not need as long to start after plugging in to the mains; only the first time is the issue.I hope this helps someone.

    Just the job
  

*by S***H on Reviewed in the United Kingdom on 18 October 2016*

Fast delivery and easy to fit. Increased the performance of my MacBook Pro for a very reasonable cost. If it gives me another few years of useful life of the computer then it's been worth every penny. Good trusted manufacturer also, Crucial are a market leader in ram chips. Highly recommended.Please hit "Yes" below if you found this review helpful. Thanks!

    A much-needed upgrade.
  

*by A***R on Reviewed in the United Kingdom on 29 July 2017*

This memory is listed as "Mac compatible" which I figured is just a marketing blurb and all of its specs matched what I required for my (Windows) laptop, so I figured I'd take the chance and buy these after my first attempt failed with a different brand of RAM, some time prior.I was skittish about booting with a different amount of RAM from hibernation, so I shut it down completely and performed the replacement. Pretty standard stuff. As another reviewer has mentioned, be sure to wait a while for the initial boot after RAM installation to complete!! It can take a while, your system/the RAM is not necessarily broken. Maybe have a snack or take a peek at the television or phone for a few minutes while your computer does its thing. After the initial lengthy boot, you will have your normal boot times back again on subsequent boots/restarts.Anyway, this new RAM works great! I finally have enough memory to accommodate all of the programs I like to run simultaneously, such as monstrous browser sessions that can easily eat 2GB of memory a piece. My system would slow to a crawl on 4GB, as it simply wasn't enough. Now it's perpetually responsive.As with all RAM upgrades though, you'll only notice a particular performance increase if you didn't have enough to start with, but you could always use the spare memory as a RAM drive for ludicrous temporary storage speeds.For determining compatibility, it can be slightly complicated. If you look up your system's processor/motherboard on the manufacturer's site, it can usually give you precise details on what type of memory - and how much of it - is compatible with your system. It's what led me to this product in particular. I think Crucial also has a web-app that can help you determine compatibility by providing it with your computer's model.Overall, very pleased with this purchase.
