Good morning, I have a problem with my Antminer DR, when I enter the configuration panel in the status tab of the miner, in the ASIC Status part I only see a visible card with (oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooo) no the others are reflected giving a hash rate of between 1 to 2.5 TH / s in the pool, when the team of 7.8 TH / s. Motivated I have heard to restart the computer when it loads the 3 cards are reflected but after a few minutes X are placed and only one is working, I refresh it again and they are no longer shown leaving only one card working.
