I have a latitude D510 with a socket 479 celeron m dothan 1.4ghz I used for work a year or two ago. I would like to give it a better processor. I have a pentium m 2.0ghz socket 478 processor in the house I was thinking about using and was curious if that would work. I'm not sure on the compatibility of the chipsets or if the pin difference would matter. If it wouldn't work could anyone offer any suggestions?
