5 yr old imac was slowing down significantly with its original 2x2G chips. Bought and installed the 2x4G chips from Crucial, now runs like a new computer. Excellent!
Works on my iMac 21.5" mid 2011 perfectly!
Great product - easily upgraded my iMac from 8 to 16 GB with this item, and makes the iMac more useful. Always have bought my memory from Crucial and never had an issue.
Upgraded iMac memory from 4GB to 16GB and now this thing FLIES! Ordering was easy - the online tool made it easy to determine the correct memory type and the order arrived promptly.
I enjoy the website for its accuracy and convenience. Keep up the great work. You guys provide a valuable service.
Great product. Great business. Easy to buy. Arrived at my home when promised. Easy to install.
Installed easily, and after rebooting, configured perfectly. Took no more than just a few minutes to install. Went from 4 GB to 12 GB....
Easy to install, shipped quick, compatible with my 2011 imac
This was easy to install in my iMac (mid-2011) and made a huge difference. I was running with 4gb of memory (2-2gb cards) and now I have 12gb (with the 2 new 4gb cards). I can now use 4gb for Parallels and Quicken (for pc) and it runs quickly and with no problems. I used to have only 1gb for Parallels and it wasn't even close to enough. And I still have 8gb to run the iMac side and that is more than enough.
Good 8G of extra memory for my iMac with 4G already installed. What a difference. The Crucial brand was recommend online and so far i agree.
