hello everyone, I currentely bought 2 sets of 16GB (2x8GB DDR3L - 1866 SODIMM for a ram upgrade of my iMac Retina 5 27inch late 2015. After installing the 32GB of Crucial ram my mac won't boot up anymore. Only once it did but after changing to another useraccount it turned black again. Somehow the problem can't be fixed and I'm out of idea's. Can somebody help ? Curcial ??? I've invested more than € 300 for a ram upgrade that doesn't work. Rip off ? In the mean time I pulled out all of te Crucial ram and changed it back to my 8GB of Apple ram and know there are no problems. Any help/advise ?
