Okay seems like I have gotten things mixed up here, apparently according to many sellers in China a QS would display its name in CPU-Z whereas an actual Engineering Sample would show none.
I am not sure if this is true or not I cannot exactly relay on this guy I wonder if you people at Intel know anything about this, I know ES and QS are not supposed to be sold in the first place but I really have no idea about these kind of things.
By looking the Qspec code QCH8 you have an Engineering Sample or a Qualification Sample. For better understanding please check the link below
