Getting: GPU #0: cudaError 30 (unknown error) calling 'result = cudaStreamSynchronize(stream)' (salsa_kernel.cu line 902) after some time running CudaMiner with GTX 750 Ti

I suspect that your overclock is a bit too extreme.

My card is not overclocked at all. It's an EVGA 750 Ti (no superclocked) running on Debian Wheezy x64 with NVIDIA-Linux-x86_64-331.49 driver and cuda-linux64-rel-5.5.22-16488124

but pressing CTRL-C and restarting cudaminer will then work again, for a while?

I've had one guy report an unknown error after some time which he required a reboot to recover.

Yes but just for some minutes. on keccak algo its crashing even faster

cbuchner1 commented 10 years ago

this is likely some kind of hardware related problem. Does your BIOS offer some options to change PCIe bus settings? e.g. dropping from Gen3 to Gen2.

Also maybe try the 314 beta driver that nVidia offers for Linux.

Good news Christian. Driver: http://us.download.nvidia.com/XFree86/Linux-x86_64/334.16/NVIDIA-Linux-x86_64-334.16.run and setting PCI-E Slot to GEN 2 made it ;-)
