I've replaced the thermal compound, now it doesn't throttle with 64 TS Bench.
That is good to know. I should probably do the same but my daughter does not run any demanding software so I have not yet bothered.
Why are you using Clock Modulation with it set to 75%? I would either reduce the turbo power limits or reduce the turbo ratio limits if you want to slow your CPU down or reduce its maximum power consumption. Clock modulation is not a smooth way to slow a CPU down.
For maximum performance, I highly recommend checking the FIVR - Disable and Lock Turbo Power Limits feature. You will need to first download RwDrv.zip from Mega and copy the RwDrv.sys file into your ThrottleStop folder to use this feature.

Intel says their CPUs can safely run up to 100°C. In a small and light laptop, with this CPU fully unlocked, high temperatures will be the result. The CPU will thermal throttle if it needs to regardless of how you have ThrottleStop setup so no worries. If your laptop is burning through your lap then reduce your turbo power limits.
Windows 10 hides some of the power profiles but they are still there. To access the Windows High Performance power profile, open up a command prompt and type in this.
powercfg /s SCHEME_MIN
To go back to the Balanced profile, type in this command.
powercfg /s SCHEME_BALANCED
On a laptop, open the Control Panel - Power Options and at the lower left you should see Windows Mobility Center. This should also give you access to the High Performance power profile without having to play around with command prompt and the powercfg command.
I prefer using the High Performance power profile and then I can adjust the Speed Shift EPP value in ThrottleStop to control the CPU. If you are using the Windows Balanced profile, there is a good chance that Windows is in control of the EPP setting and what you enter into ThrottleStop for EPP is being ignored. Open up the FIVR window and have a look at what is being reported in the top right monitoring table for EPP. The EPP value in that table is what the CPU is actually using in real time. If this value does not agree with what you are requesting on the main screen of ThrottleStop, that means Windows is in charge of EPP. Do not bother checking or adjusting the Speed Shift EPP setting in ThrottleStop if Windows is in control of EPP.
If you did not see a BSOD when testing, that is a good thing. It means you have a CPU that you can probably undervolt a little further. Every CPU is unique. No one can tell you how far you can go unless you do some hands on testing. Reduce the CPU Core and CPU Cache equally in small steps if you want to go further. You might be getting close to the limit. Watch for errors in the TS Bench test. If you see any errors, you have gone too far so back off a little.
Look at the C0% numbers in the picture you posted compared to the picture I posted. If your laptop was idle, there is more going on in the background than needs to be going on. High C0% when supposedly idle can significantly reduce battery run time. Open up the C State data. Cores should be spending 99% of their time in the low power C7 state when your laptop is idle.
