Hi to everyone. I have a crosshair v formula z motherboard with a fx8350. My problem is when i try to overclock my ram to 2400 mhz the pc does not even boot at all. When i reduce to 2133 mhz everything is ok. The ram is Corsair Vengeance Pro 2400 mhz. I think i tried all possible combinations but i cant reach 2400 mhz ram speed. Any ideas?
