CPU running at under base speed while gamming...

I need help!
Recently I got an issue in my laptop, my CPU running under base speed when I run heavy software or games on my laptop.

Temps?

probably thermal throttling

You'll probably need to undervolt the CPU with throttlestop to fix the throttling if its thermal throttling.

temp is normal
recently I change the thermal paste and clean everything, but nothing change

56 to 65 C  according to ThrottleStop

Your laptop has a throttling problem. The 8250U has a 15W TDP rating so some laptops with Intel's low power CPUs are not great for gaming. Post some screenshots of how you have ThrottleStop setup. Include the main window, the FIVR window and the TPL window. Also turn on the Log File option while gaming. Play for at least 15 minutes. When finished testing, exit the game and then exit ThrottleStop so it can finalize your log file. It will be located in your ThrottleStop / Logs folder. Attach a log file to your next post so I can see how your CPU is performing.

 

This log file will also show any reasons for throttling. When your CPU is loaded like in your screenshot, it should not be running at 0.40 GHz. Something is not right.

@Saikat Mondal Most 8th Gen laptops use Speed Shift Technology automatically. The BIOS did not enable Speed Shift so press the TPL button and enable Speed Shift in ThrottleStop. Also check the Enable Speed Shift when ThrottleStop starts option. 

 

After Speed Shift is enabled, go back to the main screen and you should see SST in green. When Speed Shift is enabled, the Set Multiplier function does not work so clear that box. Also clear the Disable Turbo box. Intel CPUs need to use Turbo Boost to reach their full rated speed. 

 

Now that Speed Shift is enabled, you can check the Speed Shift EPP box on the main screen. Set Speed Shift EPP to 80. This is a good balanced setting so your CPU can get up to full speed when it needs to but will idle down when lightly loaded. If you want full speed all of the time, set EPP to 0. Just click on the number beside the Speed Shift EPP setting and you can set EPP to whatever you like.

 

The log file shows the main problem. It is constantly displaying PL1 in the far right column. This means the CPU is power limit throttling even though power consumption is only 7 Watts. Your 8250U has a 15W TDP rating so it should not be throttling at only 7W.

 

To try to fix this problem, check the FIVR - Disable and Lock Turbo Power Limits box. Intel CPUs use multiple sets of turbo power limits. Checking this box takes care of the secondary set of turbo power limits that some computers use. After you do these fixes, do some more gaming and run another log file. It will show if the problem is solved or if I need to recommend something else.

 

You can also use ThrottleStop to undervolt your CPU. In the FIVR window check the Unlock Adjustable Voltage option and set both the core and cache to an offset of -75 mV. This should be 100% stable on your 8th Gen U CPU. If you did this right, the undervolt will show up in the monitoring table at the top right of the FIVR window. You should see -0.0752 for both the core and the cache.

 

In the right laptop model, when all of the power limit restrictions are removed, 8th Gen U CPUs are capable of running way beyond their 15W rating. HP might not allow this level of performance. Here is how a Lenovo C930 runs.
