I am new to overclocking and I was looking at possibly doing a mild overclock on the i7 3770K. By mild I am thinking I would only try for 4 GHz. What would be some risks if I wanted to do it manually? I have a Asus P8Z77-V Pro motherboard and it has a feature to automatically overclock the system. Would that be safe to use because I have heard that there has been issues using it. Any help would be great!
