The miner has been working for a week without problems but the last two days that this happens every 2 or 3 hours, some solution?
2018-03-15 3:27:04|gpu_id 2 76 0 an illegal instruction was encountered
2018-03-15 3:27:04|gpu 2 unresponsive - check overclocking
2018-03-15 3:27:04|cudaMemcpy 1 failed
Thanks!
One GPU is failing, check your Riser, or if you have an extra try to replace them.
if it happens its an open rig and have some dust then make some cleaning maintenance
