I just bought my new 27"inch 5K iMac and I get the same problem, after installing 8GBx2 2666 Mhz from OWC I got dark screen too. I am going to try another combination today because yesterday I only removed the new memory sticks and it worked again, so I will update on this as soon as I try another combinations.
