yeah, everything is at stock clocks, I have not over-clocked any card or CPU. Also, I rechecked, it started at v9.2, in v9.1 it does not kill the system:
try set minimum intensity. on my test rig with v9.2 -i 7 work stable, but v9.3, v10, v11 work stable only with -i 4
u should never need that low -i 7 should be low enough 4 that if it isnt stable then its your card clocks or not enough voltage
