Not that I am aware of. AM2/AM2+ CPUs do not have a DDR3 memory controller. AM3 CPUs have both a DDR2 and DDR3 compatible memory controller, so they can be used in either AM2/AM2+ boards (DDR2) or AM3/AM3+ (DDR3) motherboards.
But there is no mobo that will let you use DDR3 with an AM2 CPU, it's just not possible.
