How to unlock Alienware m16 r1 undervolt for ThrottleStop?

Everything is trial and error. Not a lot of people are trying to undervolt with Undervolt Protection enabled.

In ThrottleStop, open the V/F Point window and try setting V/F Point 1 to 150. Do the same for both the core and the cache.
Fill in all four profiles if you use more than one profile. I am a single profile kind of guy.

Are you still using vastly different values for the core and the P cache offsets? Try setting those two offset voltages equally. See if you are game stable at -50 mV for both. If yes, go for -75 mV and then try -100 mV.

these settings are stable for me so far, heavily gamed for 2 hours, no crashes, limited the max cores to 4ghz, my thermals are still high though (85-90C) don't know what else can I do to lower than more, I see yellow Thermal and PL2 notifications but they didn't throttle, I don't know if I can go power with my values, been testing for hours now, as for VF point should I set it just like on your screenshot? 150 point at 800mhz?

Some people like to set V/F Point 1 to the same number as their core offset. If you set the core and cache to -140 mV, setting V/F Point 1 to 140 or 150 should be fine.

Undervolting reduces voltage along the entire voltage curve. It reduces voltage equally whether the CPU is running fast or slow. This can cause instability when lightly loaded. That is the reason for using V/F Point 1 to add back the voltage that was removed at low MHz. This trick has made a big difference. Now the CPU is getting the exact same voltage at 800 MHz that it was originally getting. That is much better for stability.

The Intel GPU and iGPU Unslice usually have to be set equally or else this setting will be ignored.

I do not bother undervolting the System Agent or the E Cache. You might risk stability without reducing power consumption any meaningful amount.

thermals are still high though (85-90C)
Those are normal and safe temperatures. As long as your computer is stable, there is no need to worry too much about the CPU temperature. Intel thermal throttling works great to always keep the CPU at a safe operating temperature.

I couldn't find igpu unslice value in the bios so I didn't set it.

so you say it is useless to set values for
system agent and E cache hmm.. maybe if I set them back to 0, I may bump up the P core and P cache for better thermals..

I will try VF setting soon, right now I am gaming for 2 hours and no crashes or errors yet, and I set E cache to -120, but is not so effective I guess.

Intel thermal throttling might not work because I disabled them all from bios including prochot xD
