Oh noes this is not fair... Does it use the same Xilinx controllers? Did he supply its own custom controller?
Yes, it does.
It cycles a bit when it tunes.
Older Avalons would do this. Some times they would boot every 2-4 hours or
It means fans pick up speed just a bit every 2-4 hours.
Phill, this is pretty normal, I ran a custom firmware on a few gears and some of them needed over 10 hours, some even need a whole day to actually stop rebooting, the reason why this happens is the fact that the step-down settings are set at minimum to ensure that you are getting the best of each chip, so even if 50 chips are lowered to the frequency they like and you are left with 1 chip that needs to go lower, say chip 5
chip no 5 > frequency 450 > run for 5 mins > collect results > bad > lower frequency to current frequency -1
chip no 5 > frequency 449 > run for 5 mins > collect results > bad > lower frequency to current frequency -1
sometimes a chip may only run well at say 350, so that's nearly a 100 steps-down if each reporting cycle needs 5 mins that's 400 mins or nearly 7 hours, and then eventually that bad chip might actually not like the voltage at all, and then voltage needs to be changed and the auto-tune starts all over again, so you should allow more time, let them tune for 24 hours, if they fail, then go with the lower settings.
