I have an AMD Phenom II X2 550BE cpu, Motherboard: Asus M4A78T-E and Kingston DDR3 1333MHz CL7 2x1.
I wanted to overclock my cpu, so i did it. It's stable at 3.6GHz @ 1.45v. If I will put the vcore voltage to 1.43, my pc will become unstable. It's a big voltage for only 3.6GHz.
I have seen on the internet a lot of people who overclocked it up to 4GHz @ 1.4 STABLE!
I think my cpu is bad.
Now, in bios, everything is set to Auto. You can see the details in the attached picture. I think the voltage 1.34v is too big for only 3.1GHz.
