You're confusing physical RAM with the virtual memory space made
available to processes.

WinXP can handle 4GB of physical RAM.

Each process running in WinXP gets a 4GB virtual memory space. The top
2GB of that space is reserved for the operating system (the OS is
mapped there, and will appropriate working space for itself in that
address range). If you have exceptionally greedy applications, you can
use the /3GB switch in the boot.ini file. That will make the OS use
only the top 1GB.

I believe, but am not at all sure, that newer 64-bit CPUs with newer
mobo and 64-bit Windoze lets you have more than 4 gig,

It's much more than 4GB, but less than the theoretical max for such
things of 2**64.
