Asrock Extreme4 with 4x4G ok switch to 1.65V ?

[tallben26]

I recently built my new machine with an Asrock extreme 4 and 2 Kingston KHX1600C9D3B1K2/8GX 8GB Kit 2X4GB 1600MHz DDR3 kit for a total of 16G

from what I understand I have to change my ram voltage to 1.65V in order to enjoy the full 1600Mhz, do I simply change it in the bios from auto to 1.65? Should I change anything else or take caution to something?

Thanks
