I have a I7-2600k cpu on a MSI Z68G43A-G3 motherboard. The mobo has 2 x16 slots a 3.0 and a 2.0, the mobo will only run the 3.0 slot at 3.0 speeds if you have a 3rd gen I-core cpu. I have tried to upgrade from my AMD HD6850 video card to a MSI AMD RX 480 and it does not post on bootup. It just sits there blacked out i have tried 2 different msi AMD cards. The original powercolor amd 6850 is 2.0x16 and it still works just fine, Also i have more than enough power as i have a 1,000 watt PSU and the proper dedicated power supply cords. I am confused at the moment as to what i should do.
