my cpu speed stuck at 0.79ghz

normal it's 2.4ghz


in safe mode it works fine but in normal no

check your Windows power plan....

In "Balanced" mode, it will ramp up from 800 MHz when presented with a load. (Monitor task manager, and start a Defender scan, it should ramp up to between 1500 MHz and max turbo, bouncing around in clock speed as it does the scan...; when done, it will return to 800 MHz, if all is funtioning well and there is no other load-inducing task being performed....

In performance mode, it will sit near top non-turbo speed...

In "Economy" mode, often sits at low end, i.e., 800 MHz....

it's already in high performance

are your temps under control?

(Check BIOS for power management options /CPU clock speed settings as well, as sometimes a failed overclock attempt will default CPU settings to ultra low/conservative settings likely to allow a post...)

Try running ThrottleStop. Clear the BD PROCHOT box, check the Set Multiplier option, set that to the maximum value (27 T) and then click on the Turn On button. Make sure SpeedStep is checked and the Disable Turbo box is clear. Post a screenshot if you need some help.

didn't fix it

ThrottleStop shows that the reason your CPU is throttling is because it has reached the PL1 power limit. Open up the TPL window and see if you can adjust the Long and Short Package power limits higher. These power limits are stored in multiple locations within the CPU and memory. If ThrottleStop does not work for you then try installing Intel XTU and see if it can adjust these power limits higher.

The 4210U has a TDP power limit of 15 Watts. The PL1 turbo power limit is typically set to 15. It looks like this limit is screwed up in your laptop. It might be set to 0 so this forces it to permanently throttle.

I do not know when this problem first occurred so that makes it difficult to troubleshoot what might be causing this. It might be a problem with your bios or a problem with Windows. Make sure that you are using the latest bios available from the laptop manufacturer. Post a screenshot of the ThrottleStop TPL window. There might be a clue in there.

If your windows 10 power setting is already on high performance, go to advanced power settings and check if you have processor power management sub menu available to you to configure (so you could set the lower limit of CPU frequency a little higher or even at 100%):
If those options are not available to you can enable them by following these steps:
- On your type cover, press + R
- Type regedit to open Register Editor.
- Now you need to go to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
Double click on CsEnabled and change Value data from 1 to 0, and click OK.
- Restart your computer to apply these changes to your system.
- After restarting your computer, now you can access the full list of power plans and individual advanced settings.

The Long and Short Package Power Limits as well as the PP0 Current Limit are all set correctly. There is a secondary set of power limits in the memory that Intel XTU has access to. You can try installing XTU and setting your power limits to the same as above. The Package Power Long should be set to 15 but setting it to 25 as above is not going to hurt anything.

If Intel XTU does not solve this problem I will show you how to investigate another set of limits using RW Everything.

Are you using the latest bios version?

yes i'm using the latest bios version

Try running RW Everything, click on the Memory icon and navigate to memory location FED15900

The two secondary turbo power limits are located at FED159A0 and FED159A4

The laptop I am on does not use those limits so it shows 00000000. Your laptop probably shows some values. I will decipher these for you after you post a screenshot.

I cannot see any of your images. They are too small to make out any details. In RW Everything, click on the "dword 32 bit" button so they are in the same format as the picture I uploaded and then use a decent site to host them like imgur.com

I found something that worked for me.

I just unplugged my power supply from my laptop that was plugged for at least the last three months. This unexpectedly crashed shutdown my laptop, and then I restarted it, and there my CPU was back to normal clock speed(my normal is overclocked): 2.4 GHz with a base clock speed on 2.00 GHz.

I own a Dell Alienware M14x R1 (2011) laptop running Windows 10.



Hope it helps you !
