I have Dell XPS 9650, i7-7700Hq, GTX 1050, 512GB SSD, 16GB DD4, 4K.
I find no throttling as in Thermal, Power limit, Current limit, MB VR (from Intel XTU), No Limit reasons from ThrottleStop, No "Yes" flag under any Performance limit reasons in HwInfo64. But still processor freq sticks to 0.8-0.9 GHz, Power limiting to ~8W(both after some gaming).
Yes, I game CPU+GPU intensive programs like pubg, vrChat, csgo (all @ 1080p) .. etc. Please don't say not to game :( Ambient Temps ~ 50-60 degC, Core Temp ~ 70-80 degC (while gaming), GTX Temp 55-65 degC.
CPU+GPU Repasted. Undervolting CPU, iGPU, Cache to -125, -75, -125 mV (Adaptive) respectively. (Both done ~6 Months back, it worked until 1week back when after sometime @ gaming the processor freq drops leading to FPS drop. I limited my FPS to Max 65, drops to 10~20 ._.)
Any help in this regard is appreciated.
