Is there an solution, so that wattman will not reset the settings ?
I have not overclocked, some cards will set at a less gpu clock, to keep the temp lower,
But sometime wattman crashes and reset all and then overheats my room :-)
minersoftware will not crash only wattmann,

There is also a new AMD driver available 18.2.1, hope it is better,
Got 2 rigs with 12 AMD R9 390 and the consume much and also produce much heat
