What I meant was that raising it the smallest amount possible wouldn't kill it. My post says that he should try to raise the vcore by the smallest amount possible. A slight vcore increase will technically do damage, but it won't shorten the lifespan in an amount that you wil notice. Once you get way above the small amount I am talking about, you will start doing damage that will severly shorten the lifespan.
