I would like to give a special shout out to Stubo for so far helping me solve my crashing issue. Through multiple replies within the forum and additional through PM. Neither of my two 13 card Nvidia rigs has crashed in over 33 hours. Up from 12-18ish hours until crashing and freezing.

I had both machines at a 0/0 core/memory overlock running at 120W of power (1070 / 1070 Ti's) and 175W (1080 / 1080Ti).

I did not re-name the rigs, so both were named m1@m1-Desktop. This may have been causing an issue with the DNS registration (correct me if I am wrong Stubo).

The second thing I did was set my core to -100 and memory to +700 for mining ETH. The negative core suggested by Stubo. But keep the same power input. Nothing else was modified or changed.

I not only had an increase in my Mh/s (from 27 to 29.5) but the rigs seem stable thus far.

I will keep everyone posted if I come across anything else as I plan on setting back the original lack of overclock to see if there was any effect there or if the non-renaming was the issue.
