Will it work?

I'm guessing you mean m3a32? Isn't that a AM2+ motherboard? If so, I would say with absolute conviction, "Probably"   Especially if it supports Phenom 1.
I have a 3 year old Asus Crosshair 1 AM2 motherboard with the nvidia 590 chipset, and it works great with the latest BIOS. The only downfall I have found is that it doesn;t seem to let me adjust the core voltage. But even so, it's running with a 500 mhz overclock right now.

It's just M3A for the mobo model. The mobo is a AM2+. I was thinking it should work but would like to know for sure before I did buy a Phenom II. I had an opteron 165 in a older mobo that at the time I bought it was not supported on the mobo cpu list but it worked.   That doesn't mean I will get lucky twice.

I'm kinda surprised nobody else chimed in. But I am confidant enough that I personally would buy one.

So does anyone have a Asus M3A with a Phenom II chip inside???
How long? Notice any problems?
I have an athalon 64 X2 4200 2.2GHz, so as you can imagine, I am dying to upgrade!
But like most scared due to Asus CPU support not saying higher than Phenom 1.
I know this is an old post, but no one ever said if worked or not??
Does anyone know anyone with a Phenom 2 chip on a M3A?   Thank u in advanced.
