Amd sempron mutate Help

[merlin3040]

Hello everyone, first sorry for my English but I am using the google translator.

I have a 140 and a sempron asus motherboard m5a99x, I would like to mute x2 athlon II 440. The bios recognizes my processor but when I start windows 7 freezes. Do not know if that will put him over voltage.

I put these pictures of the bios if it helps you

The 2nd core is "weak" or damaged.
Try with default 200MHz cpu bus frequency and see if it run stable ( test with benchmarks that stress the cores ) .
