It seems there's a correlation between using temps/fan control from the miner and "NVML: cannot get fan speed, error 999 (an internal driver error occurred)" errors, causing application restart (worker restart in my case)
The rig is Win10 with 10*1060*6gb and and latest drivers. I'm using -mclock and -pwlim with no issues running v11.9, but as soon as I set -tt into anything it will lead to the error above within minutes.
I have better results with MSI AB than Claymore on Nvidia
Well... and my conclusion from the experience with MSI AB: do anything you must in order to
avoid installing AB on your workers.
Anyways I had serious stability issues with this 10*1060 rig (lately it never held over 5-6 hours of constant work) , it was behaving like it had some problems with electricity/raisers/contacts.
It was constantly restarting/and occasionally hung in a way that only power down/up would make it recover. Reset wasn't doing the trick.
Fresh system image and NO AB install and now I have it running stable at 24.1MH at actually higher mclock than it was before and no issues whatsoever for 21+ hours.
