Hi all,
I have just installed recalbox 7 on my RPi4 and tried some overclocking settings such as :
over_voltage=6
arm_freq=2140
gpu_freq=750

When running Raspberry Pi OS, this settings work fine and I can track the CPU freq using the command line
watch -n 1 vcgencmd measure_clock arm

This command cleary shows the CPU freq increasing to 2GHz and above, depending on CPU load. However when running Recalbox 7, the same command shows that the frequency stays stuck at 700 MHz.
Is there any limitation in Recalbox for overclocking a RPi4 ?
