No, they use differant sockets, pentium 3 uses Slot1 and Socket370, pentium 4 uses Socket 423, 478, and 775.
if u look inside each pcs u will see they look a lot different from one another.
Not really, both of them used sockets.
i just look at my P3 and the heat sink and fan are standing up instead of flat in P4. Guessing underneath should be different too.
In some cases you can not use certain P4s in some P4 boards. Take some time and go to www.intel.com . There is a lot of compatibility information available, but, it may take a while to dig it up. The Pentium 3 has a different socket than than all current Pent4s.
thanks guys it was really helpful and the reply was quick i would've tried this forum long time ago thank you all amalus
