DDR3 cannot fit in DDR2 slots can it?

EDIT: DDR3 and DDR2 both have 240pin so maybe they are compatible with each other.

You can't put DDR3 module into DDR2 slot, but the AM3 CPUs will include "hybrid" DDR2/DDR3 integrated memory controllers, so you will able to use AM3 CPU in your AM2+ board with proper BIOS.
