Hello, I am currently using intel i5-7600k, Corsair Vengeance LPX DDR4 2400MHz 8GB stick, and Gigabyte b250m-d3h motherboard. I recently bought a Corsair Vengeance LPX DDR4 3200MHz 16gb and thought of replacing the old ram with this one. I noticed that whatever ram I use, whichever slot I use, the frequency is stuck at 2133MHz. If I turn on XMP, it shows 2400 / 2133 instead of 2133 / 2133. but the speed I'm getting is still 2133mhz. I even tried using one of the rams and still same result. Please help
 
Your Motherboard max supported speed is 2400Mhz and not 3200Mhz. Please Read your Manual. or Specification of your Mobo.

Also your Memory is NOT in the Compatible List.

I have the same issue when I use only the 2400MHz 8GB ram, i am getting 2133MHz no matter which ram im using.
