Windows 10: Why is my cpu not running at base speed

hello


Why isn't my CPU running at it's base speed (2,9GHz) instead it's running at 3,5-4Ghz at all times, is there any fix for this?

CPU not running in full speed in Windows 10

Ok. This thread has the answer.

Windows 10 only use half of max cpu speed

This time rather than do the registry entry 58, i tried the suggestion of throttestop. Downloaded it, and now im back up to the base speed. And i believe i can turn it off essier than the registry entry.

 

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.
