Help: CPU and GPU throttling

[Mr. Kennedy]

Hi!

I've recently bougth a new laptop (HP Pavilion Power 15) and, when testing in games, saw that the CPU will throttle from his original 3.1 GHz to 2.6 or even 2.1 GHz. When checking Throttlestop, it shows that the problem is the current (it shows EDP other in Core, GPU and Ring). Here is the catch: The problem just shows up when the GPU is being stressed, but when is just the CPU, everything looks fine. Temperature-wise, the cpu runs at 65 - 75 °C when stressed, and the GPU runs at 65 - 75 °C when stressed. Not sure what is causing this problem.

Laptop specs:

-CPU: i5 7300hq

-GPU: Nvidia GTX 1050 ti

-RAM: 8 GB / 2400 MHz single channel

 

PS: Sorry for my bad english , english is not my first language.

have you adjusted the power settings

I’m not clear if you’ve undervolted the cpu with throttlestop or are just using it to measure performance. I would recommend undervolting the cpu with throttlestop, and undervolting your GPU with MSI afterburner (I believe you can use it on laptops, but I’m not 100% sure).

Right now, just using it to measure performance and see what is the problem.

Will try to undervolt the CPU and GPU and see if it works

Nope, i was scared to do anything . Will try undervolting the CPU and GPU

I recommend using intel xtu first to find a stable cpu undervolt. With MSI afterburner make sure the profiles aren’t being applied at startup.

Just finished undervolting and... well, it did boost the CPU clock to 2.8 GHz and im getting better fps in games than before (about 3 - 5 fps+), but the problem is still there. If i undervolt more, the GPU crashes and the game stops working. I dowloaded Intel XTU, and even when both CPU and GPU are undervolted, it still shows "Current limit throttling" as the problem. Should i try with a different AC power adapter?

Current limit throttling is always going to happen. Your CPU is only allowed to take so much current, but undervolting it essentially makes your laptop use the current it is supplied more efficiently (at least that's how I think it works). Before undervolt you might be current limit throttling at like 2.6ghz, and after you should still be throttling but at a higher frequency.

So basically i have to deal with it? But i've seen other laptops with similar or identical specs perform as expected... Why would that be different for my laptop? Should i just use the warranty and get my money back so i can buy another laptop?

Every laptop will throttle the CPU. You can try repasting it and undervolting but at the end of the day the cooling solution in the laptop is what it is. If you're not getting the frame rate in games that you expected then you should probably return it.

Hmm... That's a lot of work for a laptop that is basically new. Well, thanks for your help , your solution did solved it a little, but i think my best shot would be returning it and see if i can get a different laptop.

Didt say undervolt I said power settings

intel xtu is much clearer download that and see if its power limit throttling

every laptop with throttle.

My Alienware17r5 throttles to like 3.2ghz and look how thick those things are

I downloaded Intel XTU, and it flashed "current/EDP throttle" in yelloew. Not sure what that means.

Likely the power supplies/VRMs in yours are not up to par. As you say it only happens when the GPU is used it checks out, the laptop is just not able to generate enough power for both.

Open the ThrottleStop TPL window and see if you can increase the PP0 Current Limit.  Some manufacturers like HP might have decided to leave this locked so it cannot be adjusted.  You will see EDP OTHER throttling when the PP0 Current Limit is set too low.  Also try increasing the IccMax value in the FIVR window.
