What are the specs on the rig that you're having so much problems with it? In our last warehouse we had over 400 1080 Ti's and never had this issue, all of them were built the same though, just standard g4400's on asus primes and good power supplies.

Were you guys running windows 10 in that warehouse? I think that's where the instability comes from? Also this problem is unfortunately fairly common. In searching for my fix I read many threads where people were having issues with freezing. Most the time the rigs were under built, not enough ram or a faulty riser was the cause.
