Power limited - in this case frequency will grow, power consumption will be same or drop if you hit frequency/current limit, otherwise passing current will increase due to increased frequency.Ĥ. Basically same as voltage limited but from different side.ģ. Frequency limited - in this case card will either crash, or throttle frequency to follow lowered voltage. Why? Because current passthrough depends on specifics workload and NOT just random load on card, so it won't just grow, it will be same at same load, but card will drop frequency.Ģ. Or card will just outright crash due to not enough voltage. Voltage limited - in this case frequency will drop as it depends on voltage, power consumption (which already was NOT maxed out) will drop as well because of frequency drop. So, if we move our voltage limit from 1.2V to 1.1V we will have different situation based on different types of limitationsġ. ![]() ![]() ![]() Let's assume we have same exact settings except voltage limit set up, and to not imagining stuff completely i will use my card as exampleĪka - voltage cap = 1.2V, frequency limit 2770 mHz, TDC limit 226.55A (197+15%), PPT limit 264.5W (230+15%).Īlso let's not touch topic of voltage slider in Adrenaline (fact that it offsets voltage curve and does not act as direct voltage limiter) Load limited (engine, aka different bottleneck) Power draw doesn't have to be lower when you undervolt except if you cap fps.Ĭard can be (just off the top of my head):Ħ.
