This thread was helpful. I had to try every combination of configurations, i.e. ram chips in different slots, until it worked. I had 2 - 4GB OEM RAM chips installed in slot 1 and slot 3. I bought 2 - 8GB OWC RAM chips and it finally worked in this configuration: 4GB/8GB/8GB/4GB Machine is 27” iMac Retina
