Hello,
I am wondering if I were to overclock my i7 4770k would it hold the overclock? The only reason that I ask is because I have heard other people saying that they have to add more voltage as time goes on and that the chip starts to deteriorate or something along those lines. I am wondering if this is true? Also I would not be trying to go for the most extreme overclock just a mild one. Any help or advice would be greatly appreciated!
