      @rk1gaming put four back tics (````) without the parenthesis before and after blocks of code so that it looks like this:

            @rk1gaming Surround the text you pasted with four (4) backticks, one separate lines.

              I just got a brand new SD card and copied the image to it. Pu the card into the Pi, the initial install went fine and so did updating the system. I went to install the first package "DGEN" and it locked up. Why?

                @rk1gaming said in Regarding v4.4:

                Why?

                You should try determining if your problem is HW related - run a CPU stress program (like https://core-electronics.com.au/tutorials/stress-testing-your-raspberry-pi.html) and see if it still locks up. Locking is usually indicative of inadequate power supply or improper ventilation.

                    While looking the other day of the over the Raspbian updates, I've noticed they added a recent change in the firmware, specifically for the 3b+ model. The change is firmware:

                    platform: Pi3 B+ reduce sdram freq to 450 while investigations are ongoing

                    referencing a long thread in their forums (https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=208821) where lockups are reported for the new model. Some of the topic posters ran a stress test using memtester and got pretty reproducible lockups.

                    If you manage to get a stress test that would lock up the system, you might try either to update to the latest firmware (via rpi-update) or add to your config.txt file

                    sdram_freq=450

                    and see if you get a more stable system.

                      @mitu isn't 450mhz the stock speed? What are they reducing from?

                        where do I add the line in config.txt?

                          @quicksilver For the 3B+, sdram_freq seems a bit different (500). If you have one, you can check with vcgencmd get_config int from a command line.

                            @rk1gaming Just add it at the end of the file, on a separate line. But, have you been able to run any of the stress tests I've been mentioning ?

                              No, but I was able to run a rom for 3 and a half hours just now.

                                by the way, I did have my Pi 3 B+ in a case and took it out. I have a ceiling fan kinda blow directly on the Pi and it still locked up after 3 hours. IDK!

                                  @rk1gaming slightly off topic but why are you installing dgen?

                                    I installed it because it is a good SEGA Genesis emulator for Windows, at least it was.

                                      I updated the raspberryPi's firmware and that seemed to do the trick. It doesn't lock up anymore. Thanks for all the help.

                                        @rk1gaming dgen is pretty outdated and doesn't have the benefit of retroarch controls. In most cases the default emulators that have been selected by the retropie team work best. For Genesis use lr-genesisplusgx. Can also use lr-picodrive as an alternative if needed.

                                            @rk1gaming Glad you got it sorted out. Just for curiosity, can you run vcgencmd get_config int from the terminal and post the output ?
