Hi all,

I'm trying to mine scrypt but cc miner keeps crashing after a few minutes.

I tried 2.2.2 CUDA 9 and get error:

[2017-10-11 22:40:02] GPU #1: Err 30: unknown error (salsa_kernel.cu:186)
[2017-10-11 22:40:02] GPU #1: Err 30: unknown error (salsa_kernel.cu:187)

And with 2.2.2 CUDA 7.5 the error:

[2017-10-11 22:57:54] GPU #0: Err 30: unknown error (salsa_kernel.cu:752)
[2017-10-11 22:57:54] GPU #0: Err 30: unknown error (salsa_kernel.cu:752)
[2017-10-11 22:57:54] GPU #0: Err 30: unknown error (salsa_kernel.cu:164)
[2017-10-11 22:57:54] GPU #0: Err 30: unknown error (salsa_kernel.cu:165)
[2017-10-11 22:57:54] GPU #0: Err 30: unknown error (salsa_kernel.cu:166)
[2017-10-11 22:57:54] GPU #0: Err 30: unknown error (salsa_kernel.cu:167)
[2017-10-11 22:57:54] GPU #0: Err 30: unknown error (salsa_kernel.cu:170)


When I restart ccminer it says "No CUDA devices found".


The only way I've found to fix it is to restart the server.


I've tried all versions of NVIDIA drivers from

http://www.nvidia. com/Download/index.aspx?lang=en-us

and

https://developer.nvidia. com/cuda-downloads?target_os=Windows&target_arch=x86_64&target_version=Server2012R2&target_type=exelocal


I'm connecting via Google Chrome Remote Desktop rather than RDP as I know this causes issues.


Any expert advice much appreciated?

Thanks in advance for your time
