I have this iMac : iMac (Retina 5K, 27-inch, Late 2015) and for now 4x8 Gb 1867 MHz DDR3.
Is it possible to put 4 x 16 Gb 1867 MHz DDR3 into this type of iMac ?
What is the maximum.
Thanks for your answers.

+1 on the recommendation for getting the RAM from OWC. 64GB is over Apple's "official" —and outdated—max RAM specs but lesser RAM brands/quality often won't allow you to reach those higher levels. We know OWC tests in Macs so they are my go-to supplier when I need to install more RAM than Apple said when the newer, larger modles were not available.

YES, you can install 4X16 GB RAM modules in your iMac. 64 GB is the max that will work in your machine. i would recommend you purchase RAM from OWC.
