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.
I have noticed that, I thought it was my clock settings and wasted 20mins of my life earlier lol, however im not gonna rollback my GPU drivers just to get 20ish hashes/sec, that'd be like going to linux to earn a few more hashes/sec, tons of work for not much gain and i like updates they generally fix misc. things so im sure the next update will pickup 20 hashes/sec how it has in the past, I use Geforce Experience to custom clean install drivers and am on "experimental updates" all my rigs are the same and they all did drop about 20 hashes/sec on my 1080z and 1070s, about 12ish on 1060z, about 7 on 1050 ti's, pm me with you're clock settings and ill pm with mine back

im always fiddling with clocks lol
