ThrottleStop FIVR 'Not Available', TPL not functioning on i5 11300H

[Sphaela]

Hi, My laptop is a ASUS TUF Dash F15 FX516PM with a i5 11300H and RTX 3060 laptop GPU. My OS is Windows 11 home edition. I've been struggle to undervolt or change PL with my i5 11300H with ThrottleStop. In FIVR, all the settings are greyed out like below:

I've make sure that core isolation is disabled on my machine but the FIVR is still 'Not Available'. I also tried to mod my bios to unlock the voltage control, but the problem persists. I read other posts in the TS forums, and think that since it shows 'Not Available' and not 'locked' I'm not looking at a bios issue. I know from other posts that 11 gen G series CPUs have no FIVR controls but 11400H has it so I think 11300H should also be fine. Should I do a clean install of a Windows 10 next? I'm really out of idea.

Also, I've notice my PL setting is not functioning. When I set the PL1 and PL2 value in TPL, HWinfo can read the PL change but the processor still hits 40W/35W PL2. And the 40W limit is also weird because the factory settings of PL1 and PL2 is 64W(as shown by both HWinfo and TS). When I first boot up my PC the processor can run to a 40W with no limit reasons, here's a screenshot while running TS Bench:

But after a gaming session or a 3DMARK run, the processor will be limit to 35W with PL2 as limit reason while running TS Bench:

I've tried tons of method online but have not got any progress. I'm really desperate right now and if anyone can help me it would be really appreciated. Thanks in advance!

As far as I know, the 11300H does not support CPU voltage control. That is why ThrottleStop reports Not Available. I have heard that the 11800H will show Locked in the FIVR window. A locked CPU can be unlocked but you cannot do anything if the FIVR window reports Not Available.

Some laptops use an embedded controller (EC) which can set turbo power limits lower than the MSR or MMIO power limits that ThrottleStop can control. ThrottleStop has no access to the EC power limits. If your laptop decides to power limit throttle at only 35 Watts, there is nothing that ThrottleStop can do to fix that.

The EC power limit value can change at any time. If you play a game or run a benchmark that activates the Nvidia GPU, the EC power limit will be lowered. The power budget is being shared. Less power for the CPU and more power for the Nvidia GPU. After you are finished using the Nvidia GPU, some laptops forget to restore the EC power limit to its previous value.

I do not think this will make any difference. Your laptop was not designed for maximum performance of both the CPU and Nvidia GPU at the same time.

Here is an example of an 11400H which supports CPU voltage control. I have never seen an example of this working on an 11300H. I do not know why Intel made this change.

Here are a couple of CPU-Z validations.

The model numbers are similar but the actual CPUs come from two separate families. CPU-Z reports that the 11300H is Model C and the 11400H is Model D.

Thank you so much for reply. It's sad to know that 11300H does not support voltage control, even the much similar named 11400H does. So I guess that i7 11370H, which is also from Tiger Lake H35 family does not have voltage control too. It's also my first time to hear about the EC power limit. I guess I can't do anything to this i5 11300H then. As intel locked down more and more user controls, I think I will avoid buying laptops with intel CPU in the future.

I've always want to say a big thank you to you. I've used TS on my old i7 4710HQ laptop when I was in middle school. It helped me greatly since I had no money for a new laptop and my CPU was throttling at all times. You have all my respect and please keep up the good work sir!
