Yes, but what I really want to know is what the values in the following commands determine: PP_AllGraphicLevel_DownHyst --> what does it setting it to 20 do? PP_ActivityTarget (value data 30 decimal) PP_AllGraphicLevel_UpHyst (value data 0 decimal) PP_AllGraphicLevel_DownHyst (value data 100 decimal) Note that this replaces step 2+3 above Are these values referring to GPU usage? Knowing this is important so I can try to fiddle with these registry values. I want to make the GPU hover around the last 3 pstates (P0, P1, P2) when gaming with frame rate caps so I have better power savings. If these values mean percentages, then the hysteresis refers to the threshold in GPU usage between shifting to a higher or lower pstate. This is fundamentally important for me and my quest in best power efficiency while at gaming. Also, have any of you experienced the dreaded P0 memory bug at idle when changing refresh rates in monitors? This is even happening to me on my 570 even if I dont touch the vertical back porch, a setting that used to lead to P0 memory bug. Thanks in advance!
