Well AMD says it should run at 1.1V at that cpu speed. Of course that means a 1.1V steady reliable power source, not one fluctuating between 1.0 and 1.2 (although Asus tends to have rather good power convertors on their boards, although they still need a decent 12V feed). > By manually setting the vcore in the bios I can run at 1.3V at 2000MHz > without any noticeable problems.

You shouldn't need to mess with the voltages. They should be provided by the bios and cpu. I have tried acpi-cpufreq and that seemed to work on an athlon64 mobile 3200+ at least. Seemed perfectly stable to me. > I need to add that I have replaced the boxed fan (the mb handbook > states that QnQ only works with the boxed fan and heatsink).
