Undervolt Doesn't Work

[unclewebb]

When the FIVR window says Locked, it is the BIOS that has locked out CPU voltage control. Need to modify the BIOS to remove the lock bit. This is a gift from Microsoft for installing Windows 11. Some users try to go back to Windows 10 but find this is still locked.

Hi folks, having a similar problem as the OP.
Here is my screenshots:

Running Win11 and even tried deleting the .ini file as well. What should I do here?

Thanks in advance.

Bios, Advanced -> check "voltage configuration" > "on" then 0 offset

scroll down.....they are more settings

Sata configuration is the bottom and last setting

I saw that Armory Crate in Turbo profile make an overclock of your CPU (+100Mhz) and GPU (+124Mhz) so have you tried TS in different Armory Crate profile?
You can try also to uninstall Armory Crate (use the uninstall tools by Asus) just to understand if the last version of Armory Crate lock the FIVR mod.

I can try tho what I'm looking for is undervolting, not overclocking.
Will report results.

I set Armoury crate to Turbo and then turned on TS. This is what it looks like. I guess no difference.

However see the difference in CPU Frequency between Turbo (above) and Silent (here):

Also, when I try to use Armoury Crate in MANUAL mode, the only setting i can customize is the fan speed. This is ridiculous!

on Asus website the manual for GX701GX-XB78 does not exist....
I have seen in other GX701GX models that Armory Crate allows you to make more complete custom profiles
Have you tried if the intel XTU works?

 

[unclewebb]

if the intel XTU works?

ThrottleStop shows that the lock bit has been set. If ThrottleStop is locked from adjusting the voltage then Intel XTU will also be locked out.

any ideas on how to resolve?

Just as imagined, XTU is also locked:

This is how to unlock CPU voltage control in many Dell laptops.

2021 Update: Based on post and Reddit comments, the approach to unlock undervolting works for a number of models, including the XPS, Inspiron, G5, 11th Generation Intel processors, and 2021 Dell models and other lines. If it works for you, please leave a comment below so others may know...

Not sure if something similar is possible with your Asus laptop. Do some Google research and maybe you can find someone that has done something similar to their Asus laptop.

help please, I understand that deactivating virtualization works, but for my work to build containers with docker etc I need hyper-v, the temperature rises a lot and I need undervolt

 

[unclewebb]

I need undervolt

Do some Google searching for PowerMonkey.

Undervolting on Windows 11 with PowerMonkey | Mr Eggtart.

How to undervolt in Windows 11 with Hyper-V, WSL or WSL2 enabled, when ThrottleStop and Intel XTU stopped to function properly.

mreggtart.com

I am happily running ThrottleStop in Windows 10 so I have never experimented with PowerMonkey. It looks complicated compared to using ThrottleStop. Basically you have to set the voltage control register before Windows 11 starts up. Good luck.

Hey there

12700K on Asus B660-i Windows 11 (not yet updated to 22H2).
Disabled virtualization in Bios and all VT options I could find.

I’m having the same problem as OP.
Voltage control is not locked, but anything lower than 0 is ignored. Positive values work (also visible in HWInfo).

XTU says „Undervolt protection is enabled“. Does not let me alter core/cache voltages.
I know B660 chipset is limited but I thought undervolting should work.

My Bios has no Core/Cache adaptive offset options, only Auto/Manual. There is an „Actual VRM core voltage“ option with offset mode but it is buggy, as any negative values crash on boot.

@Eraserhead
Can you post a screenshot of the ThrottleStop FIVR window while you are trying to use a negative offset voltage? Enter the voltage and press the Apply button so I can see what it shows.

XTU says „Undervolt protection is enabled

Have you tried uninstalling XTU and only running ThrottleStop? I am not sure if it is XTU locking things down or if the B660 chipset has the undervolting feature deliberately locked out.

Either Intel is trying to protect their customers from any Plundervolt exploits or they would like their customers to spend some more money and buy a Z series motherboard which should have the undervolt feature unlocked.

 

[Eraserhead]

Uninstalled XTU, no change.

Minus 50.8 mV on core and cache:

Here's one with a positive offset on core:

Thanks for posting those images.

Interesting that Intel allows you to add voltage but they do not allow you to reduce voltage. This seems to be by design. I do not think there is any way to fix this limitation with the B660 chipset that you are using.

I assume that any CPU multiplier overclocking will also be ignored by the B660 chipset.

Thank you anyway!

Yep, OC is locked. I knew that though.
TPL are unlocked and some voltage controls in Bios. I now have to wait for Asus to fix that bug, apparently they’re working on it (saw some comments on their Forum).
