Where did you get it from?
Also, what voltage are you needing to get that overclock?
I'm American, but I ordered from French Amazon cuz they had them in stock and shipped to America. Right now i'm having huge problems installing Windows 10 though. I keep getting IRLQ_NOT_LESS_THAN_OR_EQUAL errors like 10% into the install. Right now I'm cloning another Windows 10 OS that's already installed on another machine to see if it works, and if it does I'll just factory reset that.
