        Very interesting topic. With the official support of the Pi4 with Recalbox 7, I decided to buy a 4Go Pi4 with the "GeeekPi ice tower" for the cooling.
        Depending how the dreamcast and PSPP are running, I may try to overclock it. I will post my results here if I do so. 😁

          Hi folks,

          I tested the overclocking on my RPI4B-4Go.
          I used those settings:

          # rpi4 overcloking
          over_voltage=6
          arm_freq=2140
          gpu_freq=750
          

          I added those lines (just before "include recalbox-config.txt") by following this procedure:

          mount -o remount, rw /boot
          vim /boot/config.txt
          

          I'm using this to cool down my RPI4 → Tour de refroidissement pour Raspberry
          The results are great! After 40min of Dreamcast game, the temperature stabilized to 43°C.
          I got a speed gain of about 10FPS. 😁

            Thanks everyone. This helped me overclocking my pi4. 🙂

            over_voltage=6
            arm_freq=2000
            gpu_freq=700

            Stable at 54° C in m Argon One m.2 Case.
            Dreamcast runs perfectly and even Conker's Bad Fur Day is playable now 🙂

            Yep, that game is my Crisis 😉

              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.
