Top customer reviews
I recently purchased a late 2015 27" iMac with the base 8GB from Apple as I wanted to avoid the Apple Tax and perform the upgrade myself. I also ordered a set of these from Amazon. After reading the reviews, I was sure these would be the correct memory modules. To my surprise, the DID NOT run at the full 1866Mhz but rather at 1600Mhz (See photos). I called Crucial and they confirmed that although the specs are identical, these are non mac specific memory modules. He also stated that they may have worked for other users but would not recommend them.
I recalled seeing a very similar product - [ASIN:B0181JTF66 Crucial 16GB Kit (8GBx2) DDR3L 1866 MT/s (PC3-14900) SODIMM 204-Pin Memory For Mac - CT2K8G3S186DM] - and referenced it to the Crucial Support Rep. He then confirmed that these are the ones that are certified to be compatible with Macs. The specs are identical but these are made specifically for Macs.
Save yourselves the trouble and frustration and get the CT2K8G3S186DM modules instead as they will operate at the full 1866Mhz speed.
I am only taking out 1 star as I feel that this should be specified in the description but I have no issues with Amazon or Crucial's products or services.
This memory works with the 27" iMac Retina - Late 2015 model. It is the i7 upgrade, the highest upgrade you can get from Apple.
I had no problems installing it, and everything works fine afterwards. I replaced the 8Gb of factory ram with these, and am now rocking 32Gb of ram on this beast. :)
This is one of the cases, where reviews helped me decide on my purchase, as I hope this review helps you.
I purchased this for my late 2015 5k iMac. It is functioning correctly and at the full rated speed of 1866 MHZ. I purchased this ram after buying and returning 1866 MHZ corsair vengeance ram because it caused my iMac to down clock its memory from 1866 MHZ to 1600 MHZ. So far so good. I will update my review in the future if I experience any stability issues, but do not anticipate doing so.
It was easy enough to unscrew the back(bottom) section of my laptop and switch them out, despite finding and extra screw rolling about inside (hmm...bad quality control on Lenovo's part) that hiccup aside I put the new ones in, closed it all up and everything booted up just fine.
I cannot stress enough how much, just in case, you should BACK UP YOUR COMPUTER, BEOFRE switching anything out. That way if it does not work out you have not just doomed yourself. But bottom line so you understand why I needed the upgrade and on what type of machine, yes this was and easy install (for me) and works as it is supposed to for the type of product it is. Cheers!
If you are having problems getting this to work with your laptop, please check the manufacturer's website for any BIOS updates that help.
Using it in my LATE 2015 27" iMac 5K Retina (I emailed Crucial to confirm compatibility) and it works great!
