The P6200 is Wolfdale based while the i5 label is applied to the newer architectures so, no. You might be able to move up to a P8xxx or something, but not to an i5.
Hey thanks for replying. I feel that might be mistaken, since someone said they got it to work. Also, the computer it's in is a Samsung R540-JA05 Pentium (R) D. This same model comes with an i3 core as well. The same person who got the i5 to work started out asking whether an i3 would work. That person then decided to try an i5 and claimed it worked. I'll post that link here soon.
