How to unlock Alienware m16 r1 undervolt for ThrottleStop?

[PHVM_BR]

You checked this but did you enter a value into the box beside this setting? What value are you using? This feature only works if you enter a value to tell the CPU how big of a mV boost you want. Somewhere between 100 and 150 would probably help if you are undervolting by -150 mV.

Perfect!

There is no reason to lower the voltage at 800MHz since the power/temperature consumption in this usage range is very low.
The most you will achieve with undervolt at this point is instability.

The possibility of adjusting the voltage offset per point on the curve is where XTU stands out compared to ThrottleStop.
This feature reduces this disadvantage.

So my 4070 came with stock thermal paste? How fucking great, I'm scared of opening the inverted MB, not sure it is a good idea doing it.

I agree. That is why the ThrottleStop mV Boost feature is designed to increase the minimum voltage. This can help improve stability while allowing a person to reliably undervolt more at max speed. It is a win, win feature.

Intel CPU cores should be spending 99% of their time either at full speed when they have a task to perform or they should be idle in one of the low power C states like C7. In this state the core is disconnected from the internal clock and it is disconnected from the voltage rail. It is basically sitting dormant at 0 MHz and 0 Volts. Cores should be spending virtually no time at 800 MHz. Adding a little extra voltage down low can improve stability during the transition phase between C7 and C0 without any significant cost in terms of power consumption.

The possibility of adjusting the voltage offset per point on the curve is where XTU stands out compared to ThrottleStop.

I thought about adding this feature to ThrottleStop but decided that the extra complication was really not necessary. I prefer to keep things simple. Being able to undervolt takes care of the full load voltage and the mV Boost feature takes care of the low end voltage. All of the intermediate CPU speeds are used for an insignificant percentage of time. My opinion is that there is little to be gained by trying to come up with some sort of perfect voltage curve. It is not necessary.

It is not necessary.

In my personal experience, point-of-curve tuning is best for overclocking unlocked CPUs.

For example, a 13900HX that has a maximum all-core clock of 4.9GHz.
At this clock rate it may be stable at -150mV, but if it increases to 5.2GHz, for example, -150mV may be too low.

yes I did, same value as the undervolting Core and Cache, which are also identical

There are a couple of things you can try which is how I've managed to keep my temps down on both CPU+GPU just under 75c(mainly playing Warzone i've seen these temps, but average around 60-72c) on both chips.
Just for reference, I have a X16 with 13900HK and 4080, some may disagree with this approach as you are "missing" out in performance but we are talking about the balance of longevity and performance for a laptop, we want it to last and minimising the need to replace the thermal paste so often.
The CPU is only configured to undervolt at -40mv(max limit in the bios)
Steps i've taken to keep temps down:
1. Set your RGB light configuration in Alienware command center, then uninstall anything related to Command center
2. Install https://github.com/T-Troll/alienfx-tools (your laptop should be supported), allows you to manually control your fan curve for both CPU+GPU
3. Install MSI afterburner to set a undervolt curve + figure out your GPU default boost clock(for the 4080 its 2280mhz: https://www.nvidia.com/en-gb/geforce/laptops/compare/
4. Allow MSI afterburner, AlienFX-tools to run at start up
5. In Throttlestop(the disagreement will be here), set the P-core&E-core multiplier to something you are comfortable with for daily/gaming use, I have mine set to run at 40x(4ghz), we don't want it to boost upto 5.4 or 5.8ghz whenever it wants to. Which is overkill for gaming.
6.Buy a IET cooling pad

Ok so the part about locking a core frequency cap, now I realize I cannot select the Set Multiplier box and set it.

Not sure there is any other place to do this or why it isn't possible. Do I need to boot in the advanced bios menu again to allow this?

Set Multiplier

Set Multiplier is not used when Speed Shift is enabled. Try lowering the Speed Shift Max value in the TPL window.

You can also lower the turbo ratios in the FIVR window to cap the maximum CPU speed.

Apology for the confusion, in intel XTU they use "multiplier", but you set the "multiplier" in FIVR window in throttle stop as unclewebb said.

This does the trick, thank you.
