So I'm trying to do the Penny trick on my brothers Xbox cause it got RRoD. It is out of warranty. Only problem is, I took the motherboard out and the chips that I'm supposed to put the pennies on aren't there. Theres like an outline of where they SHOULD be but nothing. This Xbox is my old one from 2008 so I'm wondering why it doesn't have them and if I can still go ahead with the penny trick?
