When no changes to overdrive settings are made, AVFS will also overvolt the card accordingly (I've seen up to 1.35V Vcore). This can potentially damage the hardware. When disabling AVFS through enabling ppfeaturemask=fffd7fff and using a custom pp_table, the max voltage of 1.2V is respected, but the core clocks are still exceeded like before. But there is a workaround: pp_table + echoing "profile_peak" or "high" to "power_dpm_force_performance_level", leads to max clocks AND voltages being respected. Even when setting it to "auto" afterwards. Maybe this points to where to look for the bug. This is also an issue under Windows, so hopefully resolving this bug on Linux will also lead to a fix on that platform (I figure, there is some code sharing, considering I get the same behavior on both). This behaviour is present since the launch of Vega. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
