Why does my i7-3537U randomly limit to 1GHz?

[JBaue1]

Since a few days I notice that it sometimes is much slower than it should be. When I open the Task Manager, this is what I see (sorry for the German):

It seems as if the CPU is limited to 0.98GHz and that's why Task Manager shows only 40% usage.

It stays this way even when I do a CPU stress test:

As you can see, the temperature should be okay with only 52°C.

If I reboot the computer, it's back at 2GHz and responds much faster:

I already thought that it could be related to the energy settings but it seems like everything is on "full power" there:

What could be the issue here?

All I can say is that it worked perfectly fine until a few days ago and I did not change any settings. I also did not change anything in Intel XTU, everything there is default and I seem to be unable to change it.

I'm using Windows 10. You can find more information about the hardware http://www.computeruniverse.net/en/products/90516315/asus-s56cb-xx372h.asp# data here.

Make sure you are running the latest Intel XTU

if possible access the bios and reset the settings to default. Besides this, make sure the power options are configured to balanced or maximized.

Dude I was having the exact same problem since I upgraded my laptop to Windows 10.

And just now, I found a solution. It is to download a software called ThrottleStop or you can just click https://www.techpowerup.com/downloads/2288/throttlestop-6-00/ Download ThrottleStop 6.00 | techPowerUp

Don't worry, this software is completely virus free.

Steps:

1. Download it.

2. Extract the .zip file to a folder.

3. Open the extracted folder and double click on the .exe file.

4. Set it exactly like this...

5. Click "Turn On".

6. Click "Save".

7. You can close the program now.

Whenever you get the 0.98 GHz problem, you can always repeat from step 3 or you can make a shortcut to your desktop to make it faster to reach.

I'm hoping this method will work for you as it works for me. Let me know if it does
