Mostly because more than the socket, the support chipset and BIOS must support the newer CPU. There are folk that flame out over this. This is not like a desktop machine. The gains look minimal too. (I used CPUBOSS)

I was wonder if it would be possible to upgrade my current Intel i7-2630QM CPU to the newer 3630QM CPU.
The sockets are the same (FCPGA98
for these two CPUs but I have an Intel HM67 Chipset but the 3630QM I think works with the HM77,76 chipsets. Is there any possibility this would be compatible with the older chipset or will it not work at all?
