-You can just change the clock multiplier for "little" overclock, but normally you change the voltage drawn by the CPU to gain stability and sometimes directly the clock ratio.
-No, it does not seem to. But you could cause some serious damage if you don't go step by step and don't know what are you doing. Try to gather all the info and experience you can before jumping into OC your CPU.
-I don't know if it is really safe or not, but i don't recommend you to do what it says withouth checking with other sources. Each CPU is a different, and maybe your CPU needs more or less voltage to get stable at certain frequency. Even it could be that your CPU can't reach the frequency the tutorial says.
Before doing any OC, try to gather all the info you can and draw your own conclusions. Go slow and adjust the multiplier and Vcore little by little to get the best results and avoid this kinf of errros.
I didn't raise the voltage at all. I'm too afraid to fuck something up and blow up my PC.
This is too hard for me. I've read so many different tutorials and every single tutorial mentions things that aren't even in my BIOS so I have no idea what to do. I really want to overclock as well but I don't even know what most of the stuff in my BIOS does.
Do you think I should just get a non-K CPU?
