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









If someone could help me I'd appreciate it.

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 ) .
