Finally some progress ! I found a thread with a couple of people having the same symptoms as I do ( [1] ), and interestingly that was with the same brand & model of card. Although there is no solution, there is a work around that works : echo -n low > /sys/class/drm/card0/device/power_dpm_force_performance_level Then the card seems stable. At least I was able to get through an entire GL benchmark and also a bunch of CL tests without crashing. (By default it crashes nearly instantly). Of course the card is slow but it's better than nothing and maybe gives a clue to a solution ? Following some advice on IRC, I also tried setting it to "high". This doesn't crash immediately when doing that and the display stays fine and I can move window and light stuff, but trying to actually run GL or CL stuff and it then crashes. I also dumped the Power Play tables, see [2]. I can't really understand them, there is definitely some weird values, but not sure if that's normal or not. As I noted earlier in the thread, when I first used the card on windows, using just AMD's driver the card was stuck at its lowest clock rate and performed poorly in benchmark. It was only after I loaded Asrock's own tweak utility that the card started to auto adapt its clock / voltages. Not sure if there is a way to dump windows power play config ?
