Using XTU to undervolt on b760

A_Concerned_Citizen — Mon, 02 Sep 2024 03:24:03 GMT

As the title states, I wish to undervolt my intel CPU on my ASUS PRIME B760-PLUS motherboard. I want to use Intel XTU as it is much more intuitive and simple than BIOS, but I can't because it tells me undervolt protection is enabled, and there is no option to disable it in BIOS. I have heard people say that to undervolt on a B760 motherboard, you have to switch to CPU microcode 0x104. Knowing there were security risks, I tried it for just a moment with the internet off and I could alter voltages in the XTU. My question is: is there another solution, or should I just bite the bullet and switch the microcode? And also, is switching the microcode safe? My current microcode is the latest one, and my processor is an Intel Core I7-13700KF. My BIOS are also updated to the latest version.

Hello A_Concerned_Citizen,

Thank you for posting in our communities.

We actually do not recommend altering the frequency and/or voltage of your processor that is outside of Intel specifications, as it might void the processor warranty.

And for the microcode, yes, it is safe to switch; however, we advise that you use the latest one as it contains the latest fix for instability and oxidation issues for the 13th and 14th generation processors.

You said that new microcode fixed oxidation issue. That's really funny. Please, do not treat Intel's customers like children.

Hello Tommy1980,

I apologize for the confusion.

What I am trying to say is that the microcode 0x129 addresses high voltages requested by the processor. This should prevent the processor from having instability issues.

So the suggestion is that once you purchase a new processor, you need to update your BIOS to the latest version to prevent having instability issues.

However, once your processor is already having instability issues, there is no more fix for that. You can report it for RMA; just contact your local Intel warranty support team.
