Question Lenovo ideapad 151ikb cpu running on low frequency

[tirax]

So I have a lenovoa ideapad 151ikb with the i7 8550U and mx150 gpu.
And for some reason the clock speed is 1.8ghz instead of 4ghz the boosting is being blocked or something.
the cpu temp is sitting on 60-70 while playing, when I am playing a game its still 1.8ghz which cause the game to have shuttering. the cpu isnt even on high load like 10-20% max
When I start the pc I have a few seconds of 4ghz clock and then I never see it again no matter what.

Is this while plugged in or running off battery?

Might be worthwhile to check through your power plan settings.

Yea its plugged, and on the power plan I set is minimum and maximum to 100%

Are you aware if anyone has ever been inside this unit to clean or repaste?

Probably something you have already considered...reset CMOS?

Many Lenovo laptops use some weird CPU throttling schemes when both the CPU and Nvidia GPU are active. Run ThrottleStop 9.6 and post screenshots of the main window, the FIVR and TPL windows when you are having problems.

In the TPL window check the MMIO Lock box which is near the top right of that window.

Turn on the Log File option and go play a game for 15 minutes. When done testing, exit the game and exit ThrottleStop. Copy and paste your log file data to,

www.pastebin.com

and post a link here so I can have a look. Turn on Nvidia GPU monitoring in the Options window before you start logging data.

Some people do not realize that Intel U series CPUs only have a 15W TDP power rating. At default settings, these CPUs can run very poorly when trying to play a game. If you have decent cooling, ThrottleStop should be able to help out.

Thank you both of you.
I did reset the cmos again and it somehow solved part of the problem like it made it be able to get tweaked to 3.8ghz finally but once the game was loaded it was random.
I ended up upgrading to windows 11 and the throttlestop program make it hold stable on 3.8ghz now.
Thaks again 😀

So its fixed as I said but there is 1 little issue, when the cpu is at 100% usage it drop to 1.8-2ghz while the temperature is stable as 75-80~
Is something in the settings wrong or its just like that?
I dont mind it will reach high temperatures on high usage since its get to 100% usage only once in 5-10min~ for maybe 10-15 seconds
These are the settings:

Post screenshots of the TPL and FIVR windows so I can see the rest of your settings. If the MSR PL1 turbo power limit is set to the default 15W value, your CPU will power limit throttle. Try increasing the MSR PL1 limit in the TPL window.

I ended up upgrading to windows 11

Did you disable VBS including core isolation memory integrity? Some Windows security features will prevent ThrottleStop from working correctly.

Update: You were right the tdp indeed was limited to 15w once I set it to higher value it keeps 3.5-4ghz most of the time thank you
