Timetec 32GB KIT(4x8GB) Compatible for Apple DDR3 1333MHz PC3-10600 CL9 for iMac (Mid 2010 27 inch, Mid 2011 21.5/27 inch) SODIMM Memory Module MAC RAM Upgrade for iMac 11,3 / iMac 12,1 / iMac 12, 2

I have an older iMac mid 2011 and I wanted to upgrade the ram from 16GB to 32GB and this did the trick. iMacs are easy to replace the ram on and this simple upgrade took me about 2 minutes. Honestly it took more time to disconnect the peripherals and get the computer off the desk than it did to replace the RAM!Once I booted everything back up it was instantly recognized and everything ran fine. The large format graphics I do for my job as a designer run smooth now, especially with the updates to the Adobe cloud needing a little more ram than usual to handle some of my larger projects for clients.Totally worth the money and not as expensive as it is from apple or other 'apple resellers' online.

IMac Mid March 2011 is officially (by Apple) designated to use 4 X 4GB. Our existing one had 2 X 4GB. The past Attempt to add additional 2 X 4GB was unsuccessful. (I had selected additional memory as per Apple specifications. I assume even though the official specifications were identical, in reality there was a mismatch between the existing 2 X 4 GB and new 2 X 4 GB.)This time decided to install all four slots with the same chips. Learned on-line that 8GB worked fine even though Apple mentions each slot is for 4GB. Installation was easy. The performance improvement is very noticeable, especially for memory hog applications such as Photos. The startup time has also significantly reduced.

They were very easy to install, and made the computer work faster than normal

Product is great. Works perfect on iMac 21.5” Mid 2011

This is an early review just post installation, but everything went as expected and no kernel panics or other issues so far. Will post another update if something comes up but currently I see no issues.This is an excellent deal for 32gb of ram.I have this memory installed in my trusty mid-2011 27” iMac with a 2.7ghz i5 and 1TB ssd which I also recently installed into this old machine. The two upgrades together are proving to give this old beast a new lease on life and it honestly runs even better than it did originally when I first bought it.Highly recommend 👍🏻

To repeat: this was used in a MacBook Pro Early 2011 13" A1278 MC700LL/A. It works! I replaced one of the original 2GB modules with this and left one in and I now have 10GB. Performance is "satisfactory", ie, I don't perceive any slowing from the chip or the mixin'n'matchin' of the 2GB and this 8GB. Of course the overall everything is faster as one would expect, especially when a virtual Windows 10 session is also running. Note that I paired this upgrade with an SSD and between the two I ended up with a pretty adequate laptop.

I purchased this set for a MID 2010 27" IMAC with i7 2.93 ghz processor. If you check Apple's website, it will tell you that these iMacs are upgradeable to only 16GB Ram (4GBx4slots) But an extensive research I have done shown me that 27" iMac (Mid 2010) models with the i7 processor can actually work with 32gb Ram (8GBx4slots) instead of 16gb. So I decided to get this set 8gbx4 as it was matching all the other requirements of Apple. The rams were recognized by the system as soon as I turned on the computer, and they did make a big difference, upgrading from 8gb to 32 GB. I do stock trading so I have several apps open at the same time, such as discord, TDA Think or Swim, Webull, Youtube and more, all at the same time and the rams handle all that with absolutely no problem. It has been almost a week, but so far, I am very happy. I also exchanged the HD withSAMSUNG 870 EVO 250GB 2.5 Inch SATA III Internal SSD (MZ-77E250B/AM) and together with the ram update, they are working miracles.

Product (8gb) arrived fast and undamaged. Install was pretty straight forward and easy. Left one original 2gb stick in the MacBook for a total of 10gb RAM. Model was a MBP A1278 from 2011. Would buy again and may grab the other 8gb stick to bump up to the full 16gb the laptop can run.

I bought this ran for my aging mid 2011 iMac 21.5’The ram was delivered on time and nicely packaged. Very easy install and works perfectly. I upgraded from the 12gb I originally had to the maximum 32gb - 4 x 8gb sticks.I’ve since upgraded the OS from High Sierra to the latest Sonoma.I’d already upgraded the hard drive to a 1tb SSD.This old iMac runs like a top! It’s like a brand machine. Just for fun I’ve ordered a 2gb graphics card to replace the tiny 512mb one and an i7 CPU to replace the i5.Yes this old Mac is the last of the truly upgradable Mac’s.If nothing else I’d recommend getting this 32gb of ram, you’ll see a massive improvement

La memoria llego en tiempo, bien empacada, funcionaron perfectamente, muy satisfecho con la compra, este kit sirve para las iMac 27in Mid 2010 i7 (en la página de apple dice que solo se puede aumentar a 16Gb pero los modelos con Quad-Core pueden llegar a 32Gb
