Wanted to try and get my pi to run a little cooler when doing nothing, seems the idle freq is 600 mhz… any chance that could be changed?
I thought adding “arm_freq_min=400” would work but it doesn’t seem to change?
You haven’t said which RPi, is a Model B, B+ or 2?
For RPi Model B and B+ for performance you should use the following:
arm_freq=900
core_freq=250
sdram_freq=450
over_voltage=2
These settings do not cause any heat issues, especially when idle.
For the RPi2 no overclock settings are required, again there should be no heat issues even when idle.
If you are really worried about heat then you could use overheat protection by setting ‘temp_limit=xx’ in your config.txt, this sets the clocks and voltages to default when the SoC reaches the defined Celsius value, setting this higher than default voids your warranty, the default is 85, you can set it lower but be warned it may cause issues with playback of media.
