Date: Thu, 25 Mar 2010 10:51:16 +0100 (CET) i don't think you're looking at the right sysctl values. you should be checking `sysctl dev.cpu.0.freq dev.cpu.0.freq_levels`. 'dev.cpu.0.freq_levels' tells you what steppings are available and 'dev.cpu.0.freq' which current stepping your cpu is using. also be sure you're running powerd (`/etc/rc.d/powerd onestart`). i'm not an expert on est though. `dmesg -a|egrep '^est[0-9]*'` reports: est0: <Enhanced SpeedStep Frequency Control> on cpu0 est: CPU supports Enhanced Speedstep, but is not recognized. est: cpu_vendor GenuineIntel, msr 925092506000925 est1: <Enhanced SpeedStep Frequency Control> on cpu1 est: CPU supports Enhanced Speedstep, but is not recognized. est: cpu_vendor GenuineIntel, msr 925092506000925 on my machine so i'm not sure how much powersaving is really being performed. your cpu might report the same. anyway it's probably better to send a message to sta...@. -- Alexander Best _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
