I started monitoring a Phenom II X6 core frequency. It seems that the Cool'n'Quiet drops
to 2400->1600->800 MHz. I even saw half the cores running at 1600 MHz and the others at
only 800 MHz. This is despite the fact that I was only loading 1 core of 6. There is no way
the thing should be overheating.
As I understand turbo-boost, if only one CPU is thrashed, it will be boosted, and three idle CPUs will drop to 800 MHz. I have not seen any boost, only
falls in core frequency. It seems to me that the active CPU is the one dropping to 800 MHz, the thing is so slow.
I also think it should not overheat with only one CPU at 100% usage. I once hit reset and went to health monitor in BIOS.
The temperature was under 60 Celcius. So I am wondering if my mainboard has a bug sending wrong signals to the X6.
