3 EVGA 1070 FTW2
1 EVGA 1060 6gb SC
DSTM

All of my rigs are running driving version 23.23.13.9135 (3/23/18) and DSTM without any issues.

Today on my smallest rig I updated to 397.31 (4/25/18) and saw a loss of "at least" 20 sols.

My average before the update was 1811sols, but after the update I was getting 1791sols and STEADILY DROPPING.

I did a rollback and everything went back to normal.

When I did the rollback, I'm now showing 24.21.13.9731 (4/22/18), however I'm getting a warning that the new 397.31 (4/25/18) is available for download.

I'm just putting the word out to at least check one rig before updating all your rigs.
