so guys i want to share my experience with you guys.

I have tried many different profiles.
Unfortunately, the above profiles do not work
for my device. when i make my cpu cache lower than -70 my laptob reboots.
Also something strange happened. when i started with the undervolts i could only undervolt my igpu up to -10 and my cpu core up to -73. when i tried again a few months later i managed to make igpu -60 and cpu core -140. however, CPU cache did not change.

I just noticed that when I start a benchmark such as cinebenchR 23 and set the turbo radio limits to 39, I still get 99 degrees.

I also focused on undervolting my graphics card. I have a total of 2 stable profiles. Which profile would you take? the one with less volts or the one with more GHz.
Strangely enough, if I choose the profile with less volts, I get more points in cinebench 21

 With 3dmark I was able to get 4100 points (without undervolting 3600 points).
What is your score? and with which undervoltings did you achieve it. What can i do for more... hahaha

Seems like the proper choice is the one with less voltage.

It appears to throttle less, therefore, you get more performance out of it.

I will try this and return with my findings also, I am one of the minorities that got blessed with a properly working, no QC issues 9700!

Hello, has anyone already found a solution in conjunction with Windows 11? Unfortunately, the undervolting no longer works although VT was disabled in the bios. Does anyone know more?
