Underclock, TPL, Speed Shift, how it works in coordination to the PC specs?

[___masrhmallow___]

I am a bit confused because a youtube guide I was following "Basic Throttlestop and Undervolting Guide", the guy max was 255 for speedshift.

My TPL speedshift goes from 1 to max 46.
I am using Speedshift EPP, I want to underclock, my TPL tab shows that the max is only 46.

Does this mean that for my PC the Speed Shift EPP should go from 1 to 46 only? (and not 255?)
The smaller the number (1) it means its overcloking, and the bigger the number (46) it means its underclocking?

If I want to underclock, which range should I go from?
1 to 46? or 1 to 255?

What should I change from these settings to reduce heat? Is the speed shift EPP correct? Are the turbo ratio limits in FIVR right?

Intel i7-11800H
Windows 11, Acer Nitro AN-547

Is this properly adjusted for undervolt and underclock?

You need to disable Windows 11 Virtualization Based Security so ThrottleStop can work correctly.

How to Disable Virtualization-Based Security (VBS) in Windows 11 to Improve Gaming

Getting frame drops while playing games in Windows 11? VBS might be the reason and here's how you can disable VBS in Windows 11.

beebom.com

Reboot and delete the ThrottleStop.INI configuration file. If you need these security features or WSL2, ThrottleStop will not work correctly.

In the TPL window, Speed Shift Max can be adjusted from 1 to 255. For your CPU, setting the Max to any value between 46 and 255 is exactly the same. It does not matter. I avoid checking the Speed Shift EPP box on the main screen. Windows can manage the EPP value on most recent computers.

Post an updated FIVR screenshot after you get VBS disabled.

Check the MMIO Lock box.

I disabled VBS, I am not sure how it might improve TS proper functioning, would be nice to have some info on how that works.
I locked TPL MMIO, not sure what it does.
I want to reduce as much as possible the heat of my laptop, as it heats a lot, I wonder if these settings are enough, or there is some I can adjust further.

Update I just enabled Thermal Velocity Boost in FIVR panel.

Not sure if I can undervolt further these settings without losing too much stability.

I disabled VBS

You have not completely disabled VBS yet. Did you follow the guide I posted? Did you also disable core isolation memory integrity?

For some laptops you might have to go into the BIOS and also disable VT-x. If all of the virtualization features are not disabled, ThrottleStop cannot read or write information to the voltage control register. I wish life was easier but there is nothing I can do about Windows 11 new and improved security features.

When virtualization is disabled, reboot and delete the ThrottleStop.INI file and try again. When this is done correctly, the FIVR window will not show a column of odd ball values in the Voltage column. This only happens when virtualization is blocking ThrottleStop from reading the voltage control register.

I cannot tell you what FIVR options are available for your computer until VBS is disabled.
The FIVR window should look like this.

I disabled completely VBS now, and the laptop does not stop crashing whenever I open throttlestop, I am guessing I never actually undervolted

(My device is in spanish).

Update:
I just deleted ThrottleStop.INI, not sure what should I be doing to avoid further crashes.
Now ThrottleStop open again, but it is restored to default settings.

Push the Aceptar button.

Yes, now TS opens, with its default settings restored, thanks.
I updated all the settings, I wonder if these new settings are enough for underclock and undervolt.

1. Adjusted the undervolt to -50 and -40 for the cache, as I had read that these are safe numbers.

2. I kept the Speed Shift EPP enabled, as you said, 46 to 255 does not matter, its the same, so I wonder if that mean that 40 is like 85% of 46 as 220 would be like 85% of 255. Does this mean that I can use 40, as if I were using 220ish?

3. I didn't touch the turbo ratio limits as I don't know if I can reduce these numbers without messing things on the laptop, didn´t found a guide for it.
