      I've done a typo in my overclocking settings.
      I'm using those settings:

      # rpi4 overclocking
      over_voltage=6
      arm_freq=2000
      gpu_freq=750
      

      @Multimaniac
      I'm glad this helped you. 😊

        Friends has the testing already resulted in stablished presets like on the pi 3 or do I need to edit directly config.txt?

          Since the overclocking is requiring a very good thermal dissipation, I guess this option will never be added to Recalbox.
          So, for now, you need to edit the config.txt file has explained few posts above.

              How amazing? Just to have an idea of the obtained performance gain. 😊

                @LapinFou Hi guys, I don't understand how you access the config.txt file under recalbox. on my sd card i only have recalbox install and not raspberry pi OS. How to access the config.txt file if you don't have Rasbian?

                      @Kilam You need to put these 3 lines in the config.txt file to get the same result as other users.
                      Remembering that Overclocking is a procedure that forces the card, then it should not be done if your Rpi does not have a heatsink and cooler. And, of course, you must do this at your own risk, I cannot be held responsible if something goes wrong.
                      Read the whole topic and you will understand better (I don't have Rpi4, I can't help you fully, I only know what I read in this topic).

                        @Zing Yes, I have a One M2 argon case.

                        I understood that it was necessary to put these 3 lines in the config.txt file

                        But where in the config file should these lines be inserted?

                          @Kilam As far as I know, there is no specific place within the config.txt file, the important thing is to add these lines.
                          All configuration lines are interpreted by the system, regardless of their order.
                          Put at the end of the file, with some identification before, as already mentioned by another user " # rpi4 overclocking" , for example (any line with the sign # in front is ignored, it is not read as a configuration).

                              @Kilam Well, you need to test some heavy games and see if you noticed a difference ...
                              You overclocked for some reason, probably some game that you wanted to perform better, the test is:
                              play and see if it improved ...

                                Dreamcast games (ex: crazy Taxi) are good benchmarks.

                                  @LapinFou Enough to play PSP and Dreamcast fighting games (Super Street Fighter II X, Street Fighter Zero 3 Saikyo-ryu Dojo for Matching Service, Street Fighter III Third Strike, Marvel Vs. Capcom, Soul Calibur, Capcom Vs. SNK, Capcom Vs. SNK 2, Guilty Gear X, Project Justice and Vampure Chronicle for Dreamcast, Street Fighter Alpha 3 MAX, Darkstalkers Chronicle, Fate/Unlimited Codes and BlazBlue Continiuum Shift Extend for PSP) no problem plus Marvel Vs. Capcom 2 only struggling in the flashy team hypersthe first time you use them, the only game still struggles in my pi I tested is Guilty Gear XX Accent Core Plus, each hit you do everything slows down

                                    @myjosito Just FYI: It should be possible to temporarily disable all overclocking by holding SHIFT key when Pi is booting according to official OC guide, no need to reinstall whole Recalbox.

                                      @Kruton Thanks for the info. But that means that the Pi has to recognize the keyboard before it freezes ?!
                                      Anyhow from october on I'm with my OC and happy with it. No more freeze, so I keep it as it is now.
                                      My only pb is still the red led not turning off when I turn off the Pi. Really not a big issue, just keep pressing the button at the rear of the Argon for 5 sec, ans that's it 🙂

                                        Just reporting: Raspberry pi 4 8 GB

                                        arm_freq=1950
                                        gpu_freq=700
                                        over_voltage=8
                                        

                                        Runs extremely well

                                        arm_freq=2147
                                        gpu_freq=700
                                        over_voltage=9
                                        

                                        "Works" but rather badly, everything is choppy and horribly slow, tons of audio chopping

                                        I think in 30 hours I will try over voltage 10 or 11

                                          @sergioad Do you really need this high voltage ?
                                          I'm running those parameters without any issue:

                                          over_voltage=6
                                          arm_freq=2000
                                          gpu_freq=750
                                          

                                          Temperature after hours of game is about 50°C.

                                          Increasing a lot the voltage will create a premature aging and/or could damage your board.

                                            @LapinFou apparently the 8 GB model uses more energy, usually people using Raspberry OS use over voltage 8 for 2147 MHz CPU and 700 MHz GPU but in Recalbox it fails
