I would like to upgrade my CPU in my Dell Inspiron 1520. I have an Intel T5250 C2D 1.5 GHz Socket P and would like to upgrade to the Intel P8600 C2D 2.4 GHz Socket P processor is there any reason I could not do so? Are there any known compatibility issues with these two processors? Thanks! P.S. I have the most current Bios as well A09
