I have 18 1070ti's that have been on RVN for about eight weeks now. 175,550,144 SMOS ... Miner restarts are very rare. Maybe twice to three times in 8 weeks. I have some 1080ti rigs on SMOS mining RVN as well ... 100,200,200 in SMOS. The only rig that reboots once or twice a week is my mixed rig ... Couple of everything ... 1070ti's, 1080's, 1080ti's ... Not really sure why that rig is different ... It never stays down long enough to get an email notification, though.
Enemy with SMOS ... I gave up on Windows months ago other than my Vega rigs. I did every thing that I could find to get them running stable in WIN10 and still had to reboot the fuckers every 12-24 hours or they would freeze up. Two dollars/month/rig is well worth the benefits of SMOS, in my opinion. Windows10 and XMR-STAK still going strong six plus months later with my Vega rigs though.
