and I used all the components again ,but this time in a GA-MA770-UD3 straight out of the box no bios update ,which is shown as supporting the 9950BE 125watt edition , and it all worked perfectly
AMD Phenom X4 9950 2600Mhz 512KBx4 2MB Agena 65nm B3 140W 4000 FA
AMD Phenom X4 9950 2600Mhz 512KBx4 2MB Agena 65nm B3 125W 4000 FA

therefore I`ll have to assume that the GA-M720-US3 ver 1 isn't capable of supporting the 125watt version , only the 140watt version
unless someone knows better that is
