The best solution I've currently found is to set "power_dpm_force_performance_level" to "manual" and "pp_power_profile_mode" to "1", and to raise the minimum core clock. E.g. on my GPU I raised the minimum core clock from 700 MHz to 1700 MHz by echoing "s 0 1700" to "pp_od_clk_voltage" and then echoing "c" to it so it applies. Interestingly, raising the minimum clock from 700 MHz to 1700 MHz only increased power consumption by about one Watt from 36 to 37 W in a game with a medium GPU load (e.g. locked at 60 fps). And idle desktop power consumption is pretty much unchanged. Increasing the minimum core clock further to 1800-2000 MHz increases power consumption in-game by just a few Watts. It's only when I increase the minimum core clock even further, e.g. 2300-2700 MHz, that power consumption increases significantly in-game. -- You are receiving this mail because: You are watching all bug changes.
