Overclocking Pi400 with recalbox 7.1.1



  • Hi everyone.

    I'm new here, and I can't find the answer to my question anywhere.

    I'm gonna receive soon a pi400. I want to use it to run exclusively recalbox 7.1.1. and ideally boost the thing a bit. I've not found the precise answer, but combining different answers concerning the overclocking of recalbox using a pi4 + overclocking a pi400, I've deduced I only need to add the following lines at the end of the config.txt file of my micro sd card :

    force_turbo=1
    over_voltage=8
    arm_freq=2200

    Can someone please confirm it will work? Thanks.

    @fredifuri Right now, the best information about it is gathered in this topic:

  • @fredifuri I agree with @Zing you will find lots of useful info in that thread, plus I lament to inform to you that apparently Recalbox is not working properly under overclocks over 2100 MHz, when using those clocks in the config.txt the CPU is set at 600 MHz, if you want to overclock it you could you

    ...
    arm_freq=2000
    gpu_freq=750
    over_voltage=6
    ...
    For pi 400 and the 4 GB of RAM Pis the recommended over voltage for that clock is 6, I would use 7, for 8 GB Pis is 8, I am using my 9



  • My settings for Rpi400, with no problems:

    over_voltage=6
    arm_freq=2147
    gpu_freq=750
