Windows 10: CPU frequency goes down to 100MHz and up again - causing UI lag.

Hi All, Issue that appears to have started after installing the 20H2 update - CPU frequency goes as far down as 100mhz 0.1GHz and then comes up again.. happens every few minute and last for 2-10 sec. where UI lags and everything is noticeably slower, mouse lags.

Laptop: Dell Precision 5510

Nothing in event viewer logs, no new windows update or Intel available

Changing power plan settings does not fix the issue.






Thanks & Br

INCORRECT CPU FREQUENCY READING

Hello Muhammad,

CPU usage depends on the applications that are open to your device. To isolate the problem, we suggest that you answer the following questions:

• Can you include a screenshot of the CPU reading?
• Have you tried performing a
  clean boot to eliminate software conflicts?
• What troubleshooting steps have you done so far?

Looking forward to your response.

 

44% CPU usage, lowered frequency, no overheat


I need some help desperately.
Attached screenshot tells everything, but here is some explanation: my computer is running very slow, HWmonitor says CPU frequency is 809MHz and 100% usage, built-in Task Manager says 44% usage, temperature is maxed at 64°C. Max CPU frequency is 1809MHz.
I can't even watch a 720p video, it lags so badly.
Power settings set correctly to max CPU utilization 100%, I am also 100% malware and virus etc. free.
CPU frequency never goes higher.
Very rarely it works fine, battling this problem for two months so far, couldn't figure out what causes it.
Drivers, BIOS, everything is the latest.
Any help or ideas much appreciated.

 

CPU frequency locks at 0.78 GHz

Hello,

My CPU get locks at 0.78 GHz and not going up or down. In the same time when CPU is locked at 0.78 GHz,

laptops fans runs fast (noisy) but the coming air is not even hot.

I have found a tool named Intel(R) Extreme tuning utility to use it as monitor of "what's going on with my system",

i'm not overclocking or changing something in CPU.

Tuning utility shows value of "Thermal Throttling" as 100% i think this is the reason why CPU stays at 0.78 GHz, it get down step because of this thermal throttling.

CPU package and core temperature is normal around 40c .

All this information is visible into this picture:



With random combination of reboots, shutdown unplug power and plug power CPU gets frequency stepping again

Thermal Throttling is becoming zero and fans stop... and everything goes normal.

Can someone explain what is connection between Windows (10) OS and CPU freq. stepping.

I think there is some connection because of available options in power plan settings, there is options Processor power management

that can control CPU min and max freq. state, but i'm not pretty sure is it related to "Thermal Throttling".
