I am facing the following situation, maybe somebody else has found a solution or know what I should look for: all my six 1070 are mining zcash as they should, until excavator crashes (it can take a few minute, or hour or days sometimes) - however when excavator resumes, in the same window, I sees only 5 of the 6 cards. Even if I restart excavator it does not see the other card. Funny thing is - the card is present in device manager.
For the card to reappear, I need to restart the rig, and it's there until excavator crashes again...


Any ideeas?
