Hello All,

I was wondering if someone can help me. I am trying to remove the power limit tdp on my dell inspiron 7490 I have the efi file from pe32.

I tried changing the IMON slope to fool the package power it shows as lower power level on Throttlestop but it still throttle pl1 and pl2.

If one can check the ifr file and give me some suggestions to tweak which options it would be excellent.


Thanks
Gee

Can you share the BIOS itself? I tried extracting the one from Dell itself, but the HDR doesn't have a full BIOS in there.

hi thanks for your help. Here is the bios which I extracted. I use Dell_PFS_Extract_v3.6 tool to extact the original downloaded exe

There is some interesting top related stuff in there, you have to experiment and see if anything actually works. There are also suppressed options relating to tdp, but those options can be changed without modding the whole bios in UEFI shell.

I couldn't find where the P0/P1 states are configured, it may not be accessible. On some cpu you can change P0/P1 settings with Intel XTU you can try and see what you can configure for your cpu in there.
