I just recently purchased 2 G.skill tridentz rgb series 16gb. My motherboard is GIGABYTE GA-Z270X-Ultra Gaming. My psu is Corsair Power Supplies , RM 850W. For some reason when i install 2 ram sticks my pc will not display anything but will turn on for about 4-5 seconds before shutting off and repeating. 1 ram stick will boot the pc and work fine. Not sure if its the mobo or not enough power coming through my psu? I just bought my new mobo also.
