I cannot go beyond 800MHz on my Dell XPS 13 Ivybridge CPU.
$ cpupower frequency-info analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 0.97 ms. hardware limits: 800 MHz - 2.60 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 1000 MHz and 2.60 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency is 800 MHz. boost state support: Supported: yes Active: yes 25500 MHz max turbo 4 active cores 25500 MHz max turbo 3 active cores 25500 MHz max turbo 2 active cores 25500 MHz max turbo 1 active cores
Even if issue
sudo cpupower frequency-set -g performance I still get 800MHz.
Then I tried
$ sudo cpupower frequency-set -f 2.60GHz Setting cpu: 0 Error setting new values. Common errors: - Do you have proper administration rights? (super-user?) - Is the governor you requested available and modprobed? - Trying to set an invalid policy? - Trying to set a specific frequency, but userspace governor is not available, for example because of hardware which cannot be set to a specific frequency or because the userspace governor isn't loaded?
...no luck. My laptop is slow especially when running on battery. I saw that there was an open bug here which seems to be similar to my experience but it was closed for not enough info. Can someone help me please?
I booted with the
intel_pstate=disable option and now I can set frequencies and governors. However my laptop is still slow and unresponsive even in performance mode, so there's something else giving problems.
