You have to take ownership of the mcupdate file away from Windows before you can delete it.

When CPU voltage control is locked, the turbo ratios are also locked. Your BIOS is not setting these...

If it was not a BIOS update then it was a microcode update. The ThrottleStop FIVR window to the right of the PowerCut command will show you what microcode version your CPU is using. Your recent...

At the top middle of the ThrottleStop FIVR window it shows, FIVR Control - Locked. Good bye CPU voltage control. This also locks the turbo ratio limits so you cannot adjust those either.

Some...

Recent BIOS updates have disabled CPU voltage control on many laptops. In ThrottleStop 9.2, open the FIVR window and at the top of the middle column does it say Locked? If it does say Locked, try...

Intel uncovered a security vulnerability called Plundervolt. Intel decided that blocking CPU voltage control while in Windows would be the easiest and cheapest way to handle this problem.

Your CPU under volt is way more aggressive compared to what other 9750H owners are using. Back it off significantly. What sort of stability testing have you done? I would reduce the CPU under volt to...

Your log file with BD PROCHOT disabled shows a much more consistent 40.00 multiplier. This is how your CPU should be running. Previous log files were showing random drops towards an average 32...

The sensor triggering BD PROCHOT could be power / current related. There is nothing excessive for power consumption in your log file so to me it looks more like an overly aggressive sensor or one...

The Add Limit Reasons to Log File option is automatically checked on the newer TS versions. That is why you cannot find it in the Options window.

In the far right column of the log file you will...

EDP OTHER across all 3 domains is sometimes caused by the PP0 Current Limit. Increasing that can help.

Interesting that you already returned your laptop once due to a BD PROCHOT issue. I find this...

BD PROCHOT stands for bi-directional processor hot. It is a signal path to your CPU. Any sensor, power, temperature or whatever, can send a signal down this line. This will force your CPU to throttle...

Your CPU is using Core C7 like it should be. It looks like the Package is being limited to C3. That is not ideal for power consumption but is pretty typical. Your CPU supports package C8 but it...

Now you know what setting controls those EDP alarms. Most desktop boards set the current limit sky high so it does not interfere with CPU performance, ever. If setting the current limit to 160 is...

The PP0 Current Limit does not have a slider. What did you try and change? Post a screenshot of the TPL window.

Did you disable the C states in the BIOS? Your idle temps and package power seem...

In ThrottleStop, try raising the PP0 Current Limit as well as the IccMax current limits. Raise all of these sky high and see if it makes a difference. I would also suggest uninstalling Intel XTU.

When you set an under volt, does it show up in the monitoring table in the top left corner of the FIVR window.

In the lower right corner of the FIVR window, ThrottleStop has a safety feature. ...

This seems to be a common problem across many different laptops. My Lenovo laptop gets limited to Package C2 whenever I resume from sleep. Not good for battery run time when this happens.
...

A sensor went bad, probably on your motherboard. This sensor is permanently sending a throttling signal to your CPU using the BD PROCHOT signal path. Disabling BD PROCHOT in ThrottleStop is...

Prime95 testing is important but it is only testing your CPU when it is fully loaded. At full load, the maximum multiplier will decrease and it might decrease significantly if there is any thermal...

Asus has started locking voltage adjustment on some of their recent laptops. You will have to contact customer support to try and find out why.

If ThrottleStop can solve your problem, why not set it up properly? It has a Start Minimized option so it will not popup. It has other options like Stop Data so you can leave it running in the...

Here is a registry mod to disable everything except C0 and C1.

Maybe you can play with that registry...

Intel has always used extra voltage. This allows Intel to guarantee long term stability without having to do a lot of long term stability testing. Imagine how much CPUs would cost to produce if...

If Intel Extreme Tuning Utility does not let you adjust your multipliers then use ThrottleStop instead. With ThrottleStop you can set your multipliers to whatever you want.

If you want to use the...

The 4710HQ has a TDP rating of 47 Watts. *When running a stress test like Prime95, the CPU would like to consume WAY more than 47 Watts. *For long term use, Intel designed this CPU to throttle back...
