द्वारा cpufrequtils स्थापित करने के बाद sudo apt-get install cpufrequtils
, कमांड द्वारा दी गई जानकारी को देखें cpufreq-info
, फिर एक फाइल बनाएं - sudo nano /etc/default/cpufrequtils
- और इसे नीचे दी गई तस्वीर में जांच के रूप में लिखें। आपके मामले में अधिकतम और न्यूनतम समान मूल्य होंगे।
GOVERNOR="ondemand"
MIN_SPEED="800MHz"
MAX_SPEED="950MHz"
अंतिम रूप से परिवर्तन करने के लिए कमांड कार्रवाई करता है और स्थायी होता है (जब बूटिंग को छोड़कर, वह है) sudo /etc/init.d/cpufrequtils restart
, जिसके परिणामस्वरूप यह आउटपुट होता है cpufreq-info

analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 800 MHz - 1.20 GHz
available frequency steps: 1.20 GHz, 1.07 GHz, 933 MHz, 800 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 800 MHz and 950 MHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 933 MHz.
