I have a question. I have one of those and was wondering that as far as i know i have another slot for CPU on the Logicboard. Is it possible to plug another one of those Dual 2.0 on it? Why the logic board have that feature if that slot stays empty? Anyone have try to put another Dual 2.0? I could buy one for £20 and make it as quad 2.0 Asking for answer with explanations why not. Not just saying "no" Thank you.
