Why do Raspberry Pi(es) produce so many invalid results?

    Hi.

    I have a PC (AMD Ryzen 9 3900XT and Nvidia GeForce 3080 with 10 MB, Windows 11 Pro) that only returns valid results. On the other hand, a Rapberry Pi 5 and a Raspberry Pi 4, both with Raspberry Pi OS 64 bit, produce about 1.5 % and 4 % invalid results respectively. What could be the reason for this? Can anything be done to prevent this?

      Hi Luca,

      It would help a lot if we knew what project (I assume Einstein?) and what task(s) you are running on the Rasberry Pi 5 and Rasberry Pi 4.  It could be that you don't have enough system memory on them.

        An error was also reported in a result delivered by the Raspberry Pi 4.

         

        What can I do? The percentage of invalid results is increasing...

          The PC produced a few days ago its first and (till now) only invalid result after about 1.5M credits earned.
