Hey, I recently upgraded my CPU from i7-6700 to i7-7700K and now when I switch memory speed from BIOS with XMP to 3200, my pc won't start. It only lets me go up to 2400, and after that it won't start again. I've tried with different voltages as well but with no results. Also after this upgrade, my 2nd monitor won't open either. Tried it with a DVI to motherboard and DisplayPort to GPU.
