for first: sorry for my english.
gpu's: 6x GTX Titan Xp
drivers: 385.12 beta
default bat for sigt
first start was with PL 100%, core +150, mem -500 : driver was crashed in few seconds
second start was with PL 100%, core stock, mem stock : rig was crashed in about 4 minutes
hmm... like as ewbf in past
ok, PL 87%, core stock, mem stock : rig stable about 10 min
next, PL87%, core +150, mem stock: rig stable
intensity as auto is 21
add -i 25 to bat and run - rig stable already 30 min

what is missing: remote monitoring, like as EWBF 0.3.4b.
update after 10h uptime, speed reduced to 323Mh (initially was 325Mh), rig working stable, no reboot, no crashes
