Hello, I am interested into overclocking my cpu from 3.8 to 4.8 ghz. So I want to be able to overclock, but I don't know what my voltage should be or the importance of it. I have the option to overclock to 6.3 ghz but I dont want to kill my PC so I am good with 4.8 ghz. I overclocked my CPU to 4.8, but then my computer froze after about an hour, then I restarted my PC. I want to be able to have my PC at 4.8 GHZ or more permanently, but don't know the best way to do it. PLZ help!
