AM2 chap, you have an AM2 motherboard
And yes the Phenom should work on your motherboard according to this site http://en.wikipedia.org/wiki/Phenom_(processor)
Ive got the Athlon 64 4200 x2, had it over a year, unfortunatly for me though ive got the older socket 939 so ill have to upgrade motherboard aswell as processor sometime soon
