NVML: cannot get current temperature, error 999 (an internal driver error occurred)



I'd say that the important part is in the bold now.
What it means that the driver has just failed somewhere and claymore just loves to do that when mixed(same miner instance) with Polarises that work alongside nvidias.
also I have a worker with 10 GPUs: 8*1060 - running claymore on "platform 1" switch with 2 Vegas fe doing XMR - no issues there.

Yeah, looks like when the screen goes black for a second it's the driver crashing, then nothing works after that. I'd be interested to learn from anyone who has a Titan X working what the magic combination of drivers and settings are.

Thanks Ursul0.

I'm also getting the "GpuMiner cu_k1 failed 30" error message. Here's the full transcript...

Right before mining starts my screen goes black for a second, then I see the error messages regarding temperature, and then "GPU 0 failed".

I'm using a Titan X on Windows 10. I started with the latest nVidia driver, then downgraded to 372.54. The Windows Fall Creators Update has been installed.

Some research says the errors are related to hardware or connection failures, but I doubt there's anything wrong with the GPU because GPU-Z is able to get temperature and fan speed.

I'm just getting started with Claymore so any advice is appreciated.
