65nm CPU on 45nm socket.

Ok 45NM CPU's are Newer. 65NM CPU's are older. You can almost always put an older CPU in a newer motherboard with the same socket but not always vise vesa IE Some Pentium D motherboards wouldn't take newer C2D/C2Q cpu's even though they were the same socket. But (almost) all C2D/C2Q will take older cpu's such as the Pentium D series.But yes your motherboard WILL take that CPU
