CCminer 2.2.2 windows server 2012 CUDA 9 or CUDA 7.5 Telsa K80 scrypt crashes

[bearface]

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

I doubt I can offer expert advice, but:

Try Teamviewer for remote access. Also try sgminer 5.6.1.

Are you using Windows Server 2012 64bit and CCMiner 2.2.2 64bit?

[bearface]

Yes I'm using using Windows Server 2012 64bit and CCMiner 2.2.2 64bit.

I thought sgminer is for AMD? I'm using an NVIDIA Telsa K80.

[gregfromo]

is ccminer build with the needed SM & Compute settings for the Tesla K80 card?

Hi

Thanks for the reply.

I don't know what they are.

I'm using

https://github. com/tpruvot/ccminer/releases

Is this correct?

Thanks

I have seen..... mining scrypt using ccminer ...... always use quite a lot cpu ......... check if your cpu is 100% used if you have several card connected. That could be one of the reason for crash after a while.

It was due to overheating, GPU0 got to 92 degrees!

Thanks guys.
