Cant revert PowerCut on i5 4th gen

[LouisFresh]

On my laptop i5 I get EDP CURRENT limit throtteling my cpu, I read somewhere on the forum about powercut so I wanted to try it.
Powercut does change the Displayed power consumption to 1W, but the EDP CURRENT limit still flashes in games.

So I wanted to revert the Powercut feature but can't. I tried deleteing the ini file and restarting but the Powercut would persist.
Is there a way to disable/revert it?

The picture below shows the current config.

This is how it looks after I delete the ini file and restart. Usually the VCCIN should be default but I changed it when I was chaning the PowerCut feature. And it seems both the Powercut and VCCIN stuck even after the ini config file was deleted and restart...

I can't get ThrottleStop to show the true Wattage anymore.

Did you try restarting your computer? Once VccIn is locked that is the only way to unlock it. Turn your computer off.

Yes, when I mentioned restart, I meant I restarted my laptop/windows restart.

Turn it completely off.

Turn it completely off.

That worked XD... I always thought restarting was better than shutting it down because of fast boot windows had enabled before...
Thanks!

Now its normal:

The other trick is to hold the Shift key down on the keyboard while you select the Windows Restart option. This should do a full restart and it should reset the CPU registers.

What is the Current Limit set to in the TPL window? That can help with EDP throttling problems. Post a screenshot of the TPL window.

I am not too familiar with the TPL limits so I didn't play with them too much.
I tired setting the Current Limit Max to 1023 (max value) but I don't think it did anything.
...
I tried it again shutting it down with Lock or without didn't do anything, and my bios is pretty much locked.

Also generally speaking what I noticed that the EDP Current throttling usually happens in games, but in ts bench or intel xtu stress test it rarely happens.
While in games my frequency can drop to 3.2ghz from the max 3.4ghz.

The TPL window shows that the PP0 Current Limit is locked to 85. You cannot change a limit that has been locked by the BIOS. You might as well set this back to 85. Setting this to 1023 is ignored by the CPU.

Some laptops will reduce the current limit any time the Nvidia GPU is active. If you run a benchmark test like XTU or Cinebench, the Nvidia GPU is not being used so the current limit might be set higher. If you play a game, the Nvidia GPU is active so your computer automatically reduces the current and power available for the CPU so there is more power available to run the Nvidia GPU. There is no solution for this problem.

Could this be a driver thing at all? Or is it purely bios, so I can't really do anything about it.

I doubt it is a driver thing but just curious, even if it was, I wouldn't go through the hassle to test all that...

I always thought that the PP0 Current Limit was written to the CPU by the BIOS. I have seen this same 85 Amp limit on a variety of 4th Gen CPUs so it is possible that Intel hard coded this value directly into the CPU. My 4700MQ with twice as many cores and threads compared to your 4210H is locked to the same 85 Amp limit. It is also locked to the same MSR power limits; 47W, 58W, 28 seconds.

That's interesting, thanks.
