Hello,
So you disabled turbo boost which means your CPU is running at the base clock frequency which is 2.2GHz on the P-cores, if you don't need the full performance from the CPU then this is ok but you could do better if the fan profiles are set to Turbo mode.
What undervolting have you done?

The above is a link to some testing I did a while back, the numbers might help you determine if your temperatures are ok.
I have since been messing around further running my CPU P-cores at 5Ghz with other tweaks in a hot environment of 29 DegC average temp.
Thanks for your reply!
I already replied to you, but I don't think it posted here, so I'll reply again.
First ot all, I made a mistake in my initial post, where I said that I disabled CPU Boost, it is partially true. I disabled it in silent mode, and in "Balanced" mode I set it as "effecient agressive", because otherwise there was as fps drop up to30-40 fps in Far Cry 4.
I also looked at your website, which is honestly very well designed and informative. However, I do not have much knowledge on these topics (undervolting, CPU clock speeds and etc), so the main part that I understood is that you got lower temperatures in the end, which is also what I'm trying to achieve
I will attach the screenshots from my G-helper app in different modes and also a screenshot from when I was playing.
Thanks again for your response and I highly appreciate your help on that topic 🙂
Trying using Intel XTU instead as this will allow you to have a higher PL limit so the CPU can maintain higher clock frequency under load and you can lower the actual Core voltages.
https://www.electrostingz.com/intel-i9-14900hx-lower-temperature-tweaks/
With such a low PL limit your CPU is being crippled and performance will tank with it. To run Intel XTU you need to disable a BIOS option, intel VT-D.
And when choose the P-cores hold CTRL and click on each one to select all in one go.
Example if I run 2.4GHz on all cores, benchmark score and temp (armourycrate turbo fan profile)
If you tried the above and your XTU temp is high perhaps your cooling is not working well and needs checking.
We are limited in terms of overclocking and voltages but as long as you only touch the options that are needed everything will be fine, always - voltage (negative).
If you get lost and cant remember what options you changed there is a default profile that is always present so use this to reset. you select the default profile, click on show values, then apply.
worse case scenario with the above is you choose a - voltage that is not stable, so the laptop can freeze / reboot. Obviously sudden BSODs do have the potential to cause data corruption.
1) What PL limit?
I will always recommend the max setting possible, the default spec for this laptop is 175W. But let me explain why so you understand a bit more. Example, take a CPU that is 2.2GHz with 8 cores and lets say 175W Power limit.
a) When all the cores are fully loaded and working to the max it requires 175W and under this condition will run the full 2.2GHz for all the 8 cores and 95 Deg C.
b) When all the cores are under a light load it requires 60W and under this condition will run all cores at 2.2GHz and 60 Deg C (out of our 175W reserve so 115W free)
You change the Power limit to 60W for this CPU. Now under the same load what's going to happen? Due to it not being able to use the full 175W it will run the 8 Cores to whatever it can with 60W.
c ) under the same heavy load it can now only manage 1.1GHz for the 8 cores and runs at 75 Deg C
d ) under the same light load it still runs all 8 cores at 2.2GHz and 60 Deg C.
So by reducing the power limit way below what the CPU needs under a fully loaded condition it will cause the CPU to lose performance, which may not be noticeable under lighter loads as power consumption is linked to workload.
Applying the above to your CPU this is the same, at 60W PL it cannot boost to the full 5.8GHz or run all the cores at 5GHz under a demanding task. What you have done is crippled the CPU's performance in order to reduce the temperatures.
In an ideal world we would want our CPU to be able to use as much power as it needs for maximum performance but heat and power is an issue with most laptops.
My goal is to maintain as much performance as possible, I want the CPU to stay at 5GHz when under any load so I let it have as much power as it needs to achieve this. If I set the PL to 60W under a fairly high load, like the XTU benchmark test it cannot maintain 5GHz, its goes down to 2.3Ghz for all the P-cores, which shows how much 60W is killing performance.
Max load, High load, light load what is what? Real world load is more important and gaming loads. Games are a mix of light CPU tasks to very CPU intensive tasks, physic calculations, rendering can be a mix especially since a lot is offloaded to the GPU. What will generally occur is that certain games might not need a lot of CPU power so a reduced power limit is not noticeable until you hit a high load area or graphically intense scene with multiple players / characters... This is why I was asking how you found the reduced power limit for the games you are playing as it is likely struggling in some aspect. But anyway my answer to this question is go for 175W and tweak the CPU ratio and voltage offset, check your temperatures and performance and go from there. If it's too hot the cooler / liquid metal may need checking.
