Only way to find out is to try it out, is it a new Q9650 like mine, i bought mine couple of weeks ago, production date end 2010 with a high VID, i can't get mine over 4200MHz, i even bought new ram (dominator GT 2000MHz).

My proc needs in bios 1.49Volt but temps are not extreme, in IBT on 100% load it rises up to 67 degrees celsius.
