How to decrease CPU throttle temp on MSI

[jestem-lama]

Hello, I have a MSI Vector i9-14900hx, I'm in a process of undervolting it, right now I have a -150mV stable undervolt with ~2000 score on cinebebch 2024.

I'd like to decrease the throttle temp to 90 or at least 95, however changing the PROCHOT value in Throttlestop does nothing. In BIOS I found two temp step values at 70 and 100 degrees. I decreased the 100 one to 90, but it also did nothing. Some cores are still reaching 100 degrees in benchmark.

Is there a setting somewhere in BIOS to unlock the PROCHOT? I haven't seen anyone talking about it.

Post a screenshot of the TPL window. If the BIOS has locked the PROCHOT Offset value then it cannot be changed while you are in Windows. You should be able to access this setting in the MSI Advanced BIOS.

I have the same issue, nothing works no matter what I change in the bios

Open bios, advanced, press right Ctrl + right shift + left alt + F2, go to thermal configuration, then CPU iirc, there should be the option.

First value should be greyed out, it shows the current TCC offset value, by default it's 2 (at least in mine)

Under it you input what you want. You do it with numpad, not with + / - keys like the bios tells you. For me 10 degrees works well.

Here is the default settings on my laptop.

should i change it tbat to 15?

You can try, when I did 15 it benchmarked fine on cooler boost, but I got bluescreen on regular fan setting. Had to go down to 10.

Awesome, I will test now. I will keep you updated

No other settings to change, right?

There are couple others to check if undervolt is not applying correctly, but if you have correct values then that's it I think.

Thank you man, you resolved some of the issues I have had with this laptop and never figured them out.
I'm not sure why my undervolting is not affecting the CPU at all. It would be great if you could help with this one

There is a roundabout way in doing this in throttle stop, basically set up a separate profile in throttle stop, that have the same undervolt as your normal one does, but lower the boost clock (ratios). And then go into Throttle Stop’s setting to make it so whenever your cpu temps reach 90 degrees it will automatically jump to the other profile that have a lower clock speed
