I found rather informative thread regarding turbo-boost here: Disabling Intel Turbo Boost in ubuntu
I followed all the recommendations, but can't get it disabled.
I am running HP Pavilion 17-e182sr with Intel i7-3632QM (2.2 - 3.2 GHz). Its default frequency is 2.2GHz which seems to work fine for me. Since it is a laptop I don't want to overheat it. My temperatures are up to 85°C with the full load. So disabling turbo boost seems the most suitable solution.
It was super easy to disable turbo boost in Windows environment, but Linux appears to be much tricky. I've already created a script to disable turbo boost as advised by @Maythux. For the matter of facts, here are my outputs.
~$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver

SEEMS PRETTY COOL, HA? But the current CPU frequencies are
~$ cat /proc/cpuinfo | grep "MHz"
cpu MHz : 2902.539
cpu MHz : 2899.987
cpu MHz : 2908.984
cpu MHz : 2900.256
cpu MHz : 2902.136
cpu MHz : 2902.807
cpu MHz : 2962.023
cpu MHz : 2899.987
Can somebody shed some light on what am I doing wrong? Thanks for all the comments here.
