I have a system with an Intel Core i7 970 that should be able
to run at 3.2 GHz. I'm running ubuntu 12.04 and installed the cpufreq indicator
to be able
to change the governor and noticed that I only had frequencies up
to 2.0 GHz available
to me. I set
to performance and checked with cpufreq-info
cpufreq-info -c 0

analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0 1 2 3 4 5 6 7 8 9 10 11
CPUs which need
to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 1.60 GHz - 2.00 GHz
available frequency steps: 2.00 GHz, 1.86 GHz, 1.73 GHz, 1.60 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 1.60 GHz and 2.00 GHz.
The governor "performance" may decide which speed
to use
within this range.
current CPU frequency is 2.00 GHz (asserted by call
to hardware).
cpufreq stats: 2.00 GHz:4.93%, 1.86 GHz:0.03%, 1.73 GHz:0.02%, 1.60 GHz:95.02% (718654)
And
to double check:
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
1995000 1862000 1729000 1596000
How do I get all the frequencies that I should have available
to me, all up
to the 3.2 GHz?
