When I enable the X.M.P on my MOBO (b360 hd3) or I set my ram at 2666mhz the CPU red led turns on on my mobo, I have post about this before and I cannot solved it. If i set my ram at 2133mhz the red light goes off. I'm using the Vengeance led 3000mhz and I know that my mobo supports 2133, 2400 and 2666. But I'm setting it at 2666 and 2400, and there is when the red light turns on. Any idea why this is happening and how I can solve it?
