    No one can advise without knowing what system you plan to install the CPU into.

    That said, look up the original specifications on the system - if it shipped with 55 W TDP processors, as long as you have the proper heatsink, it'll work (the heatsink very often varies depending on the CPU installed, so you may have to replace it to upgrade).

    If the system did not have a 55 W CPU on offer from Dell, then it's a risky upgrade - the VRMs on the mainboard may or may not be able to supply the power requirements of the CPU -- or, the system may not be able to cope with the extra heat generated by the higher-demand CPU.  In both cases, it's a route to a stability and longevity nightmare.

    It's an unlocked CPU, not supported by the system - and draws 10 W more than the CPU the system is designed for.  It'd be an experiment - one that very well might fail.
