Rig: Ubuntu 17 64-bit, 4 Gigabyte Windforce OC 1070s , all molex risers, 2 risers powered by molex to 6 pin, other 2 powered by molex to sata then sata to 6pin.
Within 30-75 minutes of mining, EWBF Cuda Miner starts giving the error (paraphrasing): GPUX are stopped. Attemping Restart --> GPUX could not be restarted. Please reboot. Sometimes a GPU might be restarted and continues to mine. This morning, the first time I left it on for 7+ hours, all GPU had stopped mining with exit code 46. The miner just kept on going at 0sol/s.
I'm trying to figure out what might be causing these issues. I've searched around and some people with similar issues were able to fix or workaround by setting max power of each GPU to 94% out of 100%, maybe lower the OC speed ( my GPUs are sold already overclocked), or get new/better PCI-e risers.
I can try getting another set of risers, and that'll take a few days to deliver. Anyone have thoughts or prayers? How would one go about overclocking or undervolting on Linux?
