This is a discussion on Frequency scaling doesn't seem to work in 2007 for x86-64 - Mandrake ; I think all is installed correctly and configured ok: - the PowerNow! modules are loaded: [root@HAL9000: ~]# dmesg |grep powernow powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.60.2) powernow-k8: 0 : fid 0x2 (1000 MHz), vid 0x12 ...
I think all is installed correctly and configured ok:
- the PowerNow! modules are loaded:
[root@HAL9000: ~]# dmesg |grep powernow
powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.60.2)
powernow-k8: 0 : fid 0x2 (1000 MHz), vid 0x12 (1100 mV)
powernow-k8: 1 : fid 0xa (1800 MHz), vid 0xa (1300 mV)
powernow-k8: 2 : fid 0xc (2000 MHz), vid 0x6 (1400 mV)
powernow-k8: 3 : fid 0xe (2200 MHz), vid 0x2 (1500 mV)
- the 'cpufreq' and 'cpufreqd' services are started.
- /etc/sysconfig/cpufreq has 1 line: GOVERNOR=ondemand
- after I boot the GNOME CPU freq applet always says governor is "powersave"
- when I restart the 'cpufreq' service the applet says "ondemand"
- when I create a system load (e.g. with cat /dev/urandom > /dev/null)
the frequency stays at 1000 MHz.
- when I use cpufreq-selector to set a specific frequency, say 2200, the
speed still stay at 1000 MHz; the same when I choose the 'Performance'
I checked it with cat /proc/cpuinfo and with KDE System Guard.
So it seems that setting frequencies and governors does nothing. A bug
in the cpufreq package? Or some config file not setup correctly?
BTW in prevous versions of cpufreq I believe there was a program
cpufreq-info that showed available governors and frequencies and also
which ones were currently set. Why is it gone?
I have an AMD Athlon(tm) 64 Processor 3200+ running 2007 for x86_64 Club
Edition with all updates installed.
