Copilot Undervolting Guide

[ghot]

Could you comment on the undervolting profile created by Copilot? What do you think should be adjusted?

Hi @ghot 

Hi @ghot 

It's mostly nonsensical, in truth. Listing  IA DC Load Line as mV when it represents the loadline slope, for instance. 

0.060v may also be far too aggressive as a global offset; start with 0.020v and work your way up in 10mV increments. Also depending on which microcode version the BIOS is on, undervolting may be restricted for your chipset. Best to check it's actually having an impact (it's been a while since I've used 700 series).

In addition to what Silent Scone just said, be careful with AI.

I recently tried it for a sequence of calculations and the answer looked very convincing, including formulae and assumptions. However, the answer was wrong. Don't take AI answers at face-value.

Thank you for the answer. I understand perfectly well that you can't fully trust DI, that's why I turned to the forum. I couldn't find any examples for my motherboard on the Internet, I don't want to risk and experiment. At first glance, the configuration proposed by DI is not unrealistic. I want knowledgeable people to help me create the optimal undervolting configuration.

[JohnAb]

Sorry that I can't give much helpful advice on undervolting. I leave most BIOS settings unchanged and have always had a good experience in terms of performance and temperatures.

Thanks anyway for the feedback.
