throttlestop dead on windows 11

Have you done a BIOS update or a Windows update recently? If you have updated the BIOS then I would try to find and install the previous BIOS version.

I do not know what the latest trick Intel or Microsoft are using to disable CPU voltage control. Without access to the full Intel documentation and without any 12th Gen or newer hardware, I cannot come up with a fix for this problem.

Try using Intel XTU. Maybe it has a magic setting that can unlock CPU voltage control.

Thank you! I have found a temporary workaround by rolling back BIOS to 1.11.0. Now it works again

I'm not completely sure if it is an issue with the BIOS by itself or some problems between my Windows setup and the BIOS. Anyway, I've created a thread on the Dell Support forum. Hope, they will fix that in the future BIOS updates.

Can you disable the virtualization protection inside the exploit settings on the per app settings?

Just randomly changing OS wide settings like virtualisation blindly for this is a bit heavy handed.

Here's a quick update. Another person has updated the BIOS to 1.13.1 and had the same issues with undervolting. It looks like an issue with the new BIOS firmware.

There are no issues with virtualization by itself, it does not directly affect the undervolting tweaks. Usually, those problems are related to things like VBS preventing changing some memory areas.

VBS is virtualization.

VBS is virtualization.

VBS is the Virtualization Based Security. It's not the virtualization support. If you disable VBS, other apps and features still can use virtualization.

Wow its so easy to be misinterpreted.

Ok in dummy speak, VBS uses virtualization to function.

Unfortunately, it looks like Intel has released the new microcode update, which blocks undervolting on 12th and 13th gen CPUs. Here's an article: Intel blocks undervolting on Alder and Raptor Lake

Theres an update to that reddit link. Intel leaving UV blocking as an option for motherboard vendors to implement. Tbh, I doubt many mobo vendors would want to gimp their boards and watch their sales plummet.

thank you very much, i will buy AMD Ryzen laptop from now on

Hello guys.
Any news regarding undervolt on Windows 11 with WSL, VBS , HYPER-V?
Microsoft developers changing or not anybody knows?

 

[unclewebb]

@mrUlugbek
If you need to use WSL2 in Windows 11, you will need to use PowerMonkey to undervolt before Windows starts.

Thank you I compile it and boot from flashdrive

But how check it undervolted or not?

 

[unclewebb]

When VBS is enabled, I think all monitoring software is blocked from reading voltages from the voltage control register.

You will have to test indirectly. Run a consistent stress test like Cinebench or the TS Bench test and see what temperature you CPU gets to with no undervolt compared to with an undervolt. The temperature should be lower if your undervolt is working.

 

[mrUlugbek]

Ok compiled Powermonkey for core i7950H

Core -250
Cache - 125

pk->planes[IACORE].OffsetVolts = -250;
pk->planes[RING].OffsetVolts = -125;


Is it normal bench?

 

[unclewebb]

That R23 score looks normal for a 9750H.

SifaoHD`s Cinebench - R23 Multi Core with BenchMate score: 8303 cb with a Core i7 9750H

The Core i7 9750H @ 4290.5MHzscores getScoreFormatted in the Cinebench - R23 Multi Core with BenchMate benchmark. SifaoHDranks #575 worldwide and #1 in the hardware class. Find out more at HWBOT.

Do you get better Cinebench scores or better CPU temperatures when you undervolt compared to when you do not undervolt?

That is how to test.

Yes without boot Powermonkey
my score 6500-6600 but CPU temp around 77-80 c CPU clock first time 3900mhz but after powerlimit 3100 - 3200
power package showed 45w

But I read one minus of Powermonkey
After Sleep Windows 11 all changes override is it right?

I do not know the answer. Enter Sleep mode, resume and run Cinebench again. Your Cinebench score should answer your question.
