hi
i have a Intel core 2 quad CPU Q9300 @ 2.50Ghz
and also a single core pentium 4 3.2Ghz.
is there a way to switch the single 3.2 with one of the cores in the quad?
No processors do no have removable/interchangeable parts. You can change one processor to another if its the same socket and supported. But no you cant just remove a core from a processor.
