Your MacMini supports multiple cpu frequencies. Using multiple frequencies can even reduce power consumption but without reducing your cpu power. The used frequence depends on the demanded processes. Login at the Serverconsole and look to youre actual used cpu frequence

  # cat /proc/cpuinfo

  # cat /proc/cpuinfo

  # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver

  # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver

ansers with 'centrino', which means that your MacMini would use the centrino driver.

This shows 'centrino', which means that your MacMini would use the centrino driver.

 

You can see th possible cpu frequencies with the command

You can see th possible cpu frequencies with the command

  # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_availaible_frequencies

  # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_availaible_frequencies

  # 1833000 1667000 1500000 1333000 1000000

Using multiple cpu frequencies, you have to config your system as follows:

Using multiple cpu frequencies, you have to config your system as follows:

Edit the file /etc/cpuspeed.conf and uncomment the line with the driver

Edit the file /etc/cpuspeed.conf and uncomment the line with the driver

  # DRIVER="centrino"

  # DRIVER="centrino"

and save this file.

Save this file with the ':wq' command

Edit the file /etc/lilo.conf and add the append command (after the 'linear' line)

 

Edit the file /etc/lilo.conf

Add the append command after the 'linear' line

  # append="apm=off acpi=on"

  # append="apm=off acpi=on"

save the file and type

Save this file with the ':wq' command

  # lilo

  # lilo

Last but not least config the servive db so that the cpuspeed service starts when booting your MacMini:

Last but not least config the servive db so that the cpuspeed service starts when booting your MacMini:

  # signal-event post-upgrade

  # signal-event post-upgrade

  # signal-event reboot

  # signal-event reboot

From now on your MacMini should use successful the cpuspeed service to swich between multiple cpu frequencies.

From now on your MacMini should use successful the cpuspeed service to swich between multiple cpu frequencies. To control your steps, login to your serverconsole and type

Now your server should use the min cpu frequence (Success).
