Don't know if you guys noticed but Inno released an updated firmware version for the D9 dated July 6. I had been running with it for a couple of days. It didn't fix the random reboots and it didn't provide any additional configuration options. It did seem to drop my hash rate without dropping power. I will be going back to the June firmware.
I have also downgraded the firmware to June firmware because I have not noticed nothing of better performance.
