Laptop not boosting to max frequency

[Ndwolfy780]

So I recently got a Dell G7 17 (7790) and although I have had a few issues with Dell's preinstalled softwares (which Ive gotten rid of and now its fine) Ive for the most part had no issues with it. I noticed that whilst under loads It was getting hot, very hot. 100 C and above hot. It was an wasy quick fix, intsalled throttle stop and put an undervolt on it (145.5mV) and poof havent seen it get above 90 C since. But, for some reason the boost clocks didnt go up. They stayed at 3.97Ghz which is what I was getting when it was without a undervolt and still very hot. Even through the CPU (i7-9750h) was capable of 4.5Ghz. I see very occasionally a single core spike up to more around that frequency but whenever its actually under a load it stays at 3.97Ghz. 

Throttle stop's reading is saying that its not reaching any power or thermal limits. So I cant help to wonder what it is. Do any of you guys have an idea?

If it's an all core load then it's normal for the boost clock to be lower than what is advertised. Since you've more cores to do more work you can lower the boost clock and save a few Watts. Also helps to reduce heat vs having all cores at max boost frequency. If you want to see your 4.5GHz boost clock then run something single threaded.

 

>But that's false advertising

It isn't. 4.5GHz is the max boost clock (usually) one core. This has been well documented for years.

I see... Is there anything I can do to help increase all core performance however?
