Need help with over clocking

I have just finished my new build and have been experiencing stuttering such as audio stuttering. I believe this is due to my Intel i7 6700k being over clocked incorrectly in the BIOS. The ram I am using is at 3733 hz. I was hoping someone could help

Inb4 someone else asks. Have you confirmed by returning everything back to stock clock?

I've set everything in the BIOS to auto. But I've set the xmp profile for the ram to 3733

I stumbled on this article, might help :]

Which motherboard are you using?
