Clock Speeds
Pi Bits
Raspberry Pi 2 clock speeds.
After a problem with Sonarr crashing repeatedly on the Raspberry Pi 2 it was suggested on the Sonarr forum that over clocking the sdram was causing the problem.
Having overclocked my Pi I wanted to drop it back to the default speeds, but looking at the options in raspi-config for the overclock doesn’t show the default speeds for the Pi2.
By default for the Pi2: arm_freq=900 core_freq=250 sdram_freq=450 overvolt=0
If Sonarr is crashing and you have overclocked it, drop the sdram frequency to 450.
For mine running headless I have the following settings in /boot/config.txt
gpu_mem=16
arm_freq=1000
core_freq=500
sdram_freq=450
over_voltage=2
This has been stable with Sonarr for months now.
