Your hashrate is at ~50% of your's equipment normal performance. I thought that mining intensity was set wrong (ethi and dcri). After runing a short test, I found that GTX1060 are not very sensible to dcri level (at least DCR). Cranking DCR intensity from 40 to 130, the DCR hashrate increased 190% and ETH hashrate decreased 10%. Such dcri level, to halven the ETH hashrate, should be within 200-300 range, that is either stupid or unsupported by Claymore miner.
Better define explicitly your ethi and dcri, say 16/40, 16/50.
Check your BIOS settings - enable Above 4G decoding/TOLUD (works only in UEFI-enabled systems) and PCI-E speed - switch it to Gen1 or Gen2.
