You probably can, but it's not smart.. The card isn't cooled very well.. The laptop would probably overheat.. it's not a chance worth taking.. The only thing that I might OC a tiny bit is the memory since it doesn't give off that much heat, but not the core, unless I can take it upart and add a cooler on it, but it would probably void the warrenty, and I bet there is no room for the cooler anyway..
