AMD 4400+ Dual Core question

[Montauk]

I did a .txt dump from cpu-z and noticed this: "Number of cores - 2 (1 core(s) disabled)." Now what is the point of having a dual core processor if one core is disabled? How can I enable it?

 

[Didou]

Are you sure it's disabled ? When you look in the performance tab of the task manager, do you see two CPU graphs ?

 

[Tedster]

Either it is disabled in BIOS or in the control panel if you have verified it is off as Didou stated.
Bear in mind CPU-Z has difficulty reading some dual core CPUs.

I read somewhere that I should update my BIOS, but not sure how. I downloaded the update (in the form of a .BIN file) and am not sure how to apply it.

**EDIT**
Ok, I have updated my BIOS and it now shows my processor correctly in BIOS. However, when go to the performance tab of task manager I see only one CPU graph still. Any ideas?

 

[Didou]

Is it an actual Athlon64 X2 ? Maybe it's a dual-core CPU with one core gone bad that AMD is selling as a single core CPU (with the defect core disabled).

 

[Montauk]

Yes. Retail AMD Athlon64 x2 4400+.
