CPU frequency getting capped at 2.8Ghz

[Hadesxo]

Hello! I have an Asus laptop with a core i7 11370H inside. 

 

Recently I have been having an issue where when I try to play games, my CPU randomly decides to cut off and cap itself at a certain frequency within the 2.7 to 2.8 Ghz range. This is strange as in the first 5 or 10 mins of gaming the frequency sits comfortably at around 4.3 Ghz and then randomly just stops, bringing my fps down significantly. I have checked the thermals and there seems to be no thermal throttling ocurring (between 60 and 70 degrees under load). 

 

What could be the issue?

Likely a wattage limitation, I forget if 11th gen Intel laptops did dynamic power sharing or not (relatively new feature, but 11th gen might be apart of it), but there's a limited power budget on laptops that the CPU and GPU have available. Most of the time, the GPU will want the vast majority of that wattage and therefore leave only enough for the CPU to not severely limit the GPU.

 

A software like HWinfo64 will be able to demonstrate that behavior if applicable.

Could be thermal throttling, laptops are hotboxes and maybe your CPU reaches 100C+ and throttles after a while

Or maybe it's the GPU that's throttling and then the CPU don't need to boost as high

Download and run ThrottleStop 9.7.2

Post screenshots of the main window, the FIVR and TPL windows. On the main screen check the Log File box and go play a game for at least 15 minutes or as long as it takes for your CPU to start throttling. Continue playing for a few more minutes so there is some data in the log file that covers the time when your computer has slowed down. When finished testing, exit the game and exit ThrottleStop so it can finalize your log file. The log file will be in your ThrottleStop / Logs folder. Attach a log file and some screenshots to your next post.

 

Intel mobile CPUs can suddenly slow down for a wide variety of reasons. Some ThrottleStop data will help troubleshoot the problem you are having. Sometimes it is heat related but often times it is power related throttling that slows things down. 

 

Check the MMIO Lock box In the TPL window. That can help prevent the throttling method that was used in many different laptops with Intel 11th Gen mobile processors.
