In my X31 it scales between 600 and 1600 MHz, or something like that. And when I keep it around setperf 40 it avoids turning the fan on. Which is handy when for example you're compiling something and leave it by bed ;) I didn't say it was a very good reason ;) > We are thinking that states > other than 0 and 100 are not very useful.
