AM2 can ONLY run with ddr2 ram and a AM2 motherboard.( AM3 boards use ddr3 ram)

AM3 has BOTH memory controllers on the cpu. So it can work in a AM3 board with DDR3 ram as also in the older AM2+ boards( if there is a BIOS to support them both of course) with DDR2 ram. This will stay the case unless AMD removes the memory DDR2 mem controller from its AM3 cpu

You CAN NOT run a system with a AM2 cpu in a AM3 board.
