There are 2 versions of that CPU, A Socket 939 one, it exceeds the TDP limit of the board which is 95W.
There is a AM2 one that is under the 95W TDP limit.
You have the AM2 version as your board uses DDR2 RAM, AM2 is not compatible with 939 vice versa, the 939 version is 110W, 15W over the TDP limit.
There is one other 939 under the TDP limit but 939 uses DDR not DDR2.
Thank a lot man that helped so much, One more question since my board is AM2 will AM2+ chips that are 95W or under work in it? i'm not sure if it is backwards compatible.
