Asus doesn't list your motherboard by the description you've used, I believe there should be another number such m3a??? but not 3200. To me the 3200 indicates the IGP graphics set not that you didn't see those numbers. Also not all asus m3a series can address the am3 cpu's even though they support 140watt tdp. I think the model board you describe shows as an assembled system once sold. There is no reference at asus CPU support section that lists the board by the description you're using but it probobly is listed by another number, try and find that and provide that if possible.
