Windows 10: CPU speed stuck to .79 GHZ

So far I have tried everything possible to make the CPU go over .79 GHZ. The CPU that I have is an i5-9300H and has been working we for the past few months until today. Please help, I cannot get anything done.

My cpu base speed stuck at 0,8 GHz

Hello people, My cpu base speed is stuck at 0,8 GHz, otherwise my CPU is doing well. The only problem is that i now cant update window because the cpu is lower than 1GHz. Window require a CPU that is higher then at least 1 GHz. I have a Intel core i7 -4790K.

 

CPU not running in full speed in Windows 10

I am experiencing the same problem reported by mkroshana.

I have a Samsung laptop with the Intel i7-3517U CPU.
It shows a base speed of 2.40 GHz and an actual speed of .79 GHz.
I have tried so many suggested 'fixes' that I couldn't relate them all.
Here are several things I have discovered - mostly through browsing the internet:



1) I can use the Device Manager to change the Processor drivers (1 for each core) from the 'Intel Processor' to the 'Processor' (picked from driver list) and I get a steady CPU speed of 2.40 GHz.
This is a fixed processor speed and my system is dramatically faster.



2) If I use the 'Intel Processor' for the 4 cores, I get a boosted speed ranging well over the 2.40 GHz for approximately 1 minute following boot-up, after which it fades to a steady .79 GHz - never to vary from that regardless
of the load on the system (I have run stress tests).



3) If I use the 'Intel Processor' for the 4 cores and boot up in 'safe mode' I get what I suspect is the proper performance of the CPU - over 2.40 GHz when stressed and well below that when not.
This performance behavior does not go away with time.



4) I have installed temperature reporting software on my system - CAM from NZXT - and it reports CPU temperature at a fairly steady 50 - 60 Deg C, depending on the stress I put on the system.
This is well below the maximum rating for the CPU of 110 Deg C.



I did not have this problem before I migrated from Win 8.1 to Win 10, but I do not know when, after the upgrade, the problem began to occur.

 

My cpu base speed stuck at 0,8 GHz

Hi William. This is what happens when i turn off the speedStep and TurboBoost. The GHz goes down to same speed as the base speed at 0,8 GHz. I dont understand how to base speed can be stuck at 0,8 GHz. Right now its on high performance.
