- edit the RPI config to improve the perfomance within a long stable runtime
sudo nano /boot/config.txt
[all]
arm_freq=2000 # CPU Frequency
core_freq=500 # GPU Frequency
sdram_freq=500 # RAM Frequency
over_voltage=5 # Electric power sent to CPU / GPU (4 = 1.35V)
#gpu_freq=750 # GPU not in use
gpu_mem=16 # GPU Memory to minimal value
start_x=0 # don't start x-server
disable_splash=1 # disables the display of the electric alert screen
- check the new power/mem settings with following commands
lscpu
vcgencmd get_mem arm;vcgencmd get_mem gpu
- disable WiFi and Bluetooth
sudo nano /etc/modprobe.d/raspi-blacklist.conf
# WiFi disable
blacklist brcmfmac
blacklist brcmutil
# Bluetooth disable
