Undervolting not working on MSI Vector 16 HX A14V

[Karlossak]

Hi, recently i ran into overheating issues when having a second 2k monitor connected to my laptop, MSI Vector 16 HX A14V and playing games (Laptop shuts down from overheating while playing Enlisted, FFXIV, POE2, with HWInfo showing I am reaching 100 C on a few CPU cores after about 10 mins of playing)

After that, I decided to give undervolting my i9-14900HX a try, but i have been struggling to make it work.
I have disabled VBS and confirmed in msinfo32 that it is in fact disabled, but changing voltage offsets doesnt seem to do anything as per the screenshots provided.

I am a bit of a noobie when it comes to this, so what am I doing wrong? Thanks so much for any help.

I think i solved it, found out i had undervolting protection in BIOS enabled. Wanted to delete my question, but not sure how to delete the thread.
Anyways if you have any suggestions about what settings are best to help with overheating, iam all for it.

UPDATE:
After running the settings posted above, my laptop shutdown again after about 11 minutes in FFXIV, not long after taking this screenshot of HWINFO.
The laptop is pretty new, bought it in february, so maybe I should contact MSI about the issue? Idk if its normal to have this happen.

What are you going to tell MSI? That you undervolted your laptop and it is not stable. That is your problem, not their problem.

If you try to run a 14900HX at full power then it is normal for it to overheat. It will have to thermal throttle and slow down to protect itself against any damage. You can try lowering the FIVR Turbo Groups. This will slow the CPU down so it does not get so hot. You will lose some performance but it might help keep your laptop from crashing.

The other thing you can do is try lowering the turbo power limits. If the cooling system cannot manage 180 Watts of cooling then it does not make sense to have the turbo power limits set that high. Maybe 100 Watts for PL1 and PL2 would be doable. Maybe 125W. Experiment with this setting to see what temperatures you get when playing. It is summer time now so if your room temperatures are high, you might need to reduce the power consumption of your CPU so it produces less heat.

Pretty much all laptops with Intel's most powerful mobile HX processors have the same problem. There is not a cooling system big enough to keep them at a reasonable temperature. You have to be willing to compromise some performance or you can try returning your laptop for a refund. Most companies are not very eager giving customers their money back.

Wanted to delete my question, but not sure how to delete the thread.

The thread you created is very useful. It tells other users that Undervolt Protection needs to be disabled. It also talks about the extreme heat issues. If you come up with some settings so your laptop is useful for playing games, post those settings to help others.
