I know there are lots of posts about C2D in an XPS 600, but they seem to all be for 800 series of processors. So basically, what are the thoughts on a Conroe C2D working in my XPS with a Pentium D 945? The mobo is a nForce4 SLI X16 and it can handle up to 1066 FSB. Also, I have a friend that has a C2D (I think it might be an Allendale or Wolfdale), I might be able to get him to let me try it in my XPS if I get some thermal compound. What are the chances that if it doesn't work it would damage his CPU? I'm more worried about his stuff than mine, my XPS is 6 years old already.
