Can't run i7 8750H at full speed

[Mysteryguy2107]

Hey Guys! I got a dell G7 7588 with i7 8750H and during gameplay (like NFS Heat) it goes as low as 1600 MHz from 3910 MHz, the temps are fine since I've done liquid metal application on it and it never goes over 75 degrees. I tried to disable "C states" in the bios and tried to undervolt as well but still the problem wasnt solved. So what should I do to stop these MHz dips?

Go to power settings and choose high performance. Go to plan settings then advanced plan settings and under "Processor power management" set the minimum processor state to 100%.

I'm pretty sure that it's just going to throttle back because it's a laptop. It'll drop to 1.6ghz if that means keeping the laptop cool. 

 

You can make sure that your laptop is on high performance for it's power plan but I think that's all you can really do besides every other measure that you've taken.

 

Is it really impacting performance?

It might not always be the CPU temp that results in throttling. It could also be throttling due to lack of power (too much power consumption by both CPU and GPU) or some parts of the power delivery becoming too hot and being therefore throttled.

 

It's a laptop, so these are possible, even though almost never the case for desktops.

Its already running on "best performance" settings and is there any way that I can remove the power throttling by using Throttlestop since I used that app to undervolt my CPU and yes whenever it goes down to like 1.6 GHz, the framerate drops from lets say 55-60 all the way to 30-35 but that happens in NFS Heat only.

I also tried to put the maximum and minimum power state to 100% but still no luck

It's there to protect your laptop from overheating, shorting out, breaking, capacitors blowing and what else.
