PC boot loop 2x 8gb ram 1866Mhz

Hello everyone I am having trouble getting my PC to boot after upgrading from 2 sticks of 4gb 1333Mhz to 2 8gb sticks of 1866Mhz ram. The pc will boot when I only have one stick inserted but not when I use the 2nd one. I am using the 2nd and 4th dimms on my motherboard like the manual says and I even set up XMP in the bios does anyone have any idea what could be wrong?

Mobo: MSI Z97 PC Mate
CPU: I5 4690k
Ram: 2x8Gb Patriot Viper 3 1866Mhz

    Check for defective memory. Memory speed for I5 4690k is 1333MHz or 1600MHz. Higher frequencies may require OC system.

    Ok i'm pretty sure that is the case just tried switching which ram is installed by itself and one of them causes my pc not to boot so I will return them tomorrow and post if it works or not.
