Product : Acer Helios 300 PH315-52 (with bios menu unlocked)
CPU : i7-9750H
base clock is 2.6GHz and Turbo boost is 4.5GHz
my system is runing at 4.2 GHz on idle but as i start a game or stress test(aida64) my cpu clock speeds starts falling and goes below 2.1 ghz i have applied liquid metal on it and removed all the stock thermal paste,pads and putty on the cores i saw difference of -15 C and cpu is not thermals throttling but it does shows current limit throttling and PL2
i thought it must be the bios causing the problem so i got my bios advanced menu unlocked but could not find anything in bios and don't have much knowledge

    Yes there wer 3-4 options like turbo,non-turbo performance but I tried them all it doesn't make any change main reason I guess is the throttling at PL2 any idea how to fix that

    You can try to reset all setting in the BIOS.
