Hey guys i just installed new RAM in my pc but it runs at 1333MHz instead of the 1866MHz that it should do.

Processor: i7 4790K
Motherboard: Maximus VII Hero

The RAM is Corsair Vengeance Pro Series 16GB CMY16GX3M2A1866C9R.

The ram that i ran before was 8GB elixer. 2x 4GB at 1333MHz

How do i get it to run at 1866MHz can i just switch Dram from auto to 1866MHz in mobo ?

Thanks in advance :D
