I'm currently mining ERGO and I wonder what could have caused this error:
GPU3 result validation failed [autolykos2]?
[2021-11-19 08:53:56] GPU0[t1] result accepted [ 129ms] [autolykos2][1]
[2021-11-19 08:54:07] GPU2[t1] result accepted [ 115ms] [autolykos2][1]
[2021-11-19 08:54:16] GPU3 result validation failed [autolykos2]
[2021-11-19 08:54:30] GPU2[t0] result accepted [ 170ms] [autolykos2][1]
[2021-11-19 08:54:36] GPU5[t0] result accepted [ 101ms] [autolykos2][1]
It means your GPU got a result that did not pass validation on the CPU. Usually this is related to OC.
