undervolting i7 14700HX

[Grumix]

Hi everyone! I finally give up and seek for your help after a bit over a month of researching on this forum and others on how to undervolt this cpu properly after I bought a lenovo legion pro 5 16irx9.
My main objective would be to lower temperatures without having a big impact on performance or disabling turbo.
First thing I thought to lower the numbers on Long Power PL1 and Short Power PL2 (lower the watts-lower the temperatures).
I reach for those numbers without BSOD but I get some errors in HWiNFO
Indeed, lowering the watts lowered the temperatures but I get those errors in HWiNFO and I worry on the long term if it snaps something.
I even get some higher numbers on CPU Core -150,4 mV, CPU P Cache -145,5 mV and CPU E Cache -145,5 mV but those errors in HWiNFO somewhat increased a bit. (still no BSOD after running some games)
The thing is I get random BSOD when I'm downloading games over steam or when I start the laptop, it restarts one more time when the desktop appears...and that's it.
My last settings are these:
If it matters, I bought a high-end cooler pad but I use it exclusively at home. Every other day I take the laptop in different locations without cooler pad to game or to browse the internet.
Any help is appreciated, thank you!

WHEA errors are bad. If HWiNFO reports WHEA errors, your undervolt settings are not stable. Reduce your undervolt until there are no errors and no blue screens.

Start by setting the E Cache back to default, +0.0000. Most people do not see any improvement by adjusting this voltage. Undervolting this might cause instability without improving anything.

Are you using the V/F Point feature? This is a must. At 800 MHz, set V/F Point 1 for both the core and the cache to 150.

Lowering the turbo power limits like you have done can cause instability. A hot CPU is better than a CPU that is not stable. Increase the power limits back towards where they originally were. When MMIO Lock is checked, do not check the Sync MMIO box.

Reduce the core and cache undervolt to -100.6 mV. Test for stability and watch for WHEA errors at this level. Spend some time at this level. If there are any errors then try increasing the voltage. Do not try to come up with the perfect voltage settings in one day. You have to use your computer as you normally would, play a few games, and see if there are any WHEA errors or blue screens. You should never be seeing either.

Check the ThrottleStop Log File box on the main screen and run a log file while playing for at least 15 minutes. When finished testing, exit the game and then exit ThrottleStop so it can finalize the log file. Attach a log file to your next post. Also post updated FIVR and TPL screenshots so I can see what changes you have made.

Consider setting all of the turbo groups to 51. This will sacrifice some light load performance. You will probably be able to come up with a much more stable undervolt with less heat, fewer voltage spikes and fewer errors.

There a link to the Valour549 Ultimate ThrottleStop Guide that is included in the ThrottleStop folder that you downloaded. It shows the basics of setting ThrottleStop up on a 14900HX. It is well worth reading this info.
