9 out of 10 miners are working.
1 miner is giving only HW errors. Swapped USB cables, power cables and ports in hub. All others working well except this one. Could it be defective?
Try the stock frequency (600 MHz) if you haven't done so yet. Otherwise based on your troubleshooting steps it really does seem to be defective.
Running only stock frequency from the beginning. I planned to overclock after stability test.
Atari please explain how we can process this as one miner was defective from the beginning.
