Hi guys, i have an alienware m18 R1 i9 13980HX rtx4090 and the temperature is 100° in game, i disabled turbo mode, the temperature after this is good but not the performance, so i need to undervolt my cpu manually. Can u please give me the values for undervolting

Post a screenshot of the FIVR window. What values have you tried? There is lots of information in this forum and on YouTube.

@unclewebb
at first thanks for reply,
i have my laptop in performance mode (pic1) i have tried cinebench with turbo enabled "normal mode"(pic2)
after this i tried disable turbo (pic3) good temperature but low performance, and finally i tried -139 and -120 (offset voltage) -110 (cpu cache) same 100° (pic4) and also it crash in 2 times and now I tried -75 -75 but it always at 100 ° (pic5)
And now I don't know how to reduce the temperature and keep my laptop performance.

@unclewebb I think I have to reduce the values of the Core ratios ?

@unclewebb i tried this (pic6) but same temperature 100° !

I've seen m18 sustaining +180W in 10 minutes on Cinebench R23.

Yours probably finishes a 10 minute run at ~110W.

There is no undervolt that can solve a bad application of Element 31.

Your laptop needs to be repasted!
