Hi Lorys,
I have a same problem !
You mentioned that this computer has a slower CPU power issue when plugged in. Could you share your experience? I encountered a similar problem.
I have a Dell Latitude 7210 running macOS Ventura 13.5.1 and am facing a GPU power throttling issue. In high power mode at 4.3GHz, the CPU temperature rises to 70-80°C but can only sustain for a few seconds before throttling down to 0.4GHz. It takes a long time for the CPU temperature to drop to around 50°C before the power returns, and this cycle repeats.
I tried several adjustments, including setting the fan to its maximum speed of 4800 RPM, disabling Intel SpeedStep, Intel TurboBoost, and Hyper-Threading. These efforts slightly lowered the CPU temperature, but it still throttles down to 0.4GHz. Finally, by enabling macOS's low-power mode and capping the CPU frequency to 2.4GHz, I was able to keep the computer stable in unplugged mode. However, once plugged in, the CPU again briefly runs at 2.4GHz before dropping to 0.4GHz. How can I resolve this issue?
I currently believe that the computer's thermal design is suboptimal and suspect that the CPU temperature limit is set too low, causing the frequent throttling. I found that VoltageShift can not only adjust voltage and TDP but may also modify MSR to adjust the temperature limit. However, there is little detailed guidance on this online. Have you tried this approach?
I attempted to use CPUFriend to generate a custom driver to manage CPUFriendDataProvider along with CPUFriend.kext. After adding the kext files and loading config.plist using OpenCore Configurator, I encountered issues where the system would hang during the boot process and result in kernel panic after rebooting.
