 |
|
Hello,
How can I make the turbo boost on my core i7 3770k work? I cannot find anything on the internet that works for me and to be honest I got confused with all the information availabe.
I don't know what is needed to diagnose the problem but here is cat /proc/cpuinfo:

What makes you think that turbo mode does not work? I ask, because OS reporting is lousy on this topic - and many people think that turbo mode doesn't work although it's working perfectly fine...
Please post the output of the command below:
| Code: | | cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies |
If turbo mode is available, you should see something like:
| Code: | | 3501000 3500000 ... 1200000 |
You can also try the "frequency stats" page of powertop. If turbo mode is available, it will explicitly show "Turbo Mode":
| Code: |
Package | CPU 0
Turbo Mode 0.0% | Turbo Mode 0.0%
3.50 GHz 0.0% | 3.50 GHz 0.0%
3.31 GHz 0.0% | 3.31 GHz 0.0%
...

Installing powertop gives me the following messages:
| Code: | * Messages for package sys-power/powertop-2.5:
* CONFIG_DEBUG_FS: is not set when it should be.
* CONFIG_TRACEPOINTS: is not set when it should be.
* CONFIG_BLK_DEV_IO_TRACE: is not set when it should be.
* CONFIG_TIMER_STATS: is not set when it should be.
* CONFIG_TRACING: is not set when it should be.
* Please check to make sure these options are set correctly.
* Failure to do so may cause unexpected problems.
|
And probably because of that powertop fails to start with the folliwing message:
| Code: | # powertop
Failed to mount debugfs!
exiting...
|
Also:
| Code: | # cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies
cat: /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies: No such file or directory
|
It seems that I don't have cpufreq anywhere in /sys/devices/system/cpu/
| Code: | # ls /sys/devices/system/cpu
cpu0 cpu1 cpu2 cpu3 cpu4 cpu5 cpu6 cpu7 cpuidle kernel_max microcode modalias offline online possible power present uevent
# ls /sys/devices/system/cpu/cpu0/
cache crash_notes crash_notes_size driver firmware_node microcode node0 power subsystem thermal_throttle topology uevent
|
It seems like I am missing the neccessary modules.
Also should I enable the modules that powertop wants? I installed the kernel using genkernel and I am reluctant on changing any kernel setting if I don't know what id does. |

Powertop is developed mainly by Intel. It is a very valuable tool if want you to optimize power management or if you want to monitor your CPU. For that reason, the kernel options demanded by this program are enabled on my servers.
From the rest of your posting I guess that you have a recent kernel with the new "Intel P state control" driver enabled. I don't know how well this driver works, but on my system, it hides all information on turbo mode. Even output of powertop looks garbled if this driver is enabled.
I bet you will see that turbo mode works if you disable this driver temporarily. If you do that, the old and mature ACPI driver will control frequencies and you will also get output of
| Code: | | cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies |
You can disable "Intel P state control" driver either by disabling it in the kernel configuration or by setting "intel_pstate=disable" as a kernel command-line argument when booting. |

| I think "Intel P state control" is disabled in my configuration. I've linked my current kernel configuration in my original post. Can someone have a look to see if the option is really disabled? I think it is. |
