I have latest hive os 5-75 - nvidia gtx 1060 cards 3gb memory / 396.54 driver , tried also 390.59 (downgraded it to test) , ubuntu 18.04 (I believe you can see latest hive os details log)
...
cards just dont do anything , cpu usage goes high.. any ideas ?
here is log file:
...
the rig itself isnt bad it works fine with every miner , dont know where the problem is ..

Thank you for the additional info - your CPU is definitely fine and way above the required minimum for timely generation of the light cache. We have since received another similar report on the same version on HiveOS, so we will investigate further and fix the problem when we found what is causing it.
On HiveOS as well, was getting the same problem, and then I tried -gser 2, and that was able to initialize the first 5 cards until the miner detected that my other 3 cards (all NVIDIA 1060 3gb) was unresponsive and it restarted the miner again, then it just keeps going in that loop of creating the DAG for 5 cards and restarting the miner. Is there a way to delay the miner from checking the cards until the -gser 2 has a chance to create the DAG for all the cards?
EDIT: I also want to add that the current HiveOS startup for claymore can load the DAG for all 8 cards all at once.
