you can put
detect_defunct: 0
in settings area of bamt.conf. that will stop mother from rebooting. i'd guess that would just leave the thing hung up and not mining every 20 minutes instead of rebooting, but who knows.
if temps are jumping all over the place... well doesn't sound good to me.
You say you have 3 GPU on this rig. Is the GPU in the middle or on an end? Maybe swap them around and see if the problem follows the card. I had 1 of the 5 on one of my rigs that was acting up. I moved it to the end with nothing blocking the fans and it's been stable now for 5 days.
Mother just put noGPU0 back into the ACTIVE directory, so its not even running now, however, it just rebooted again... now its the second core on that same card that got the OC removed... I had it at 800/300... sigh....
BitMinerN8:
Its at the top and currently running about 10C higher than the middle and bottom card with one core disabled and the other at stock. I'll try moving it to the "bottom" slot.. I have an open air rig, so the "bottom" slot runs the coolest as nothing is in its way... I assume there is no way to determine GPU numbers it will be if I move it? I thought I remember reading somewhere that it was just based on the motherboard.
If i still have issues, I'll try resetting the thermal paste/heatsink.. and if still issues... I'll finish beating my head on a wall and return it as i just bought it on ebay, lol.
