This is probably a dumb question...

Will a Socket 515 P4 mobo take a P4 Socket 478 processor?

ummm im assuming you mean a socket 775 as there is no 515, but no a 775 will not take a 478

I think you are referring to this Pentium 4 "515", which is a socket 775 CPU:

It will not fit in a socket 478 P4 board.

There are lots of socket 775 Intel CPUs, but not all of them work with all socket 775 motherboards--a new motherboard will generally run the older ones, but an old motherboard generally won't run the newest ones.

If you can post the make and model of your motherboard (use CPU-Z at

http://www.cpuid.com/cpuz.php

)

there is usually a way to find out what upgrade CPUs are compatible.
