Use x86info -mhz. It shows my cpu speed going up and down, even when I have speedstep disabled. As I understand it, it slows down when the kernel sends idle instructions. If you want to make sure your cpu is running full tilt, I'd recommend running a compile (maybe a kernel, which is nice and big). With speedstep on (and running on battery) that always pins me at 500 mhz, and I see 700 mhz while compiling without speedstep. -- David Roundy http://civet.berkeley.edu/droundy/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
