ROG Strix SCAR 18 (2023) - Undervolt using AC/DC loadline values

Refering to this post on reddit : https://www.reddit.com/r/intel/comments/10dcjd9/intel_blocks_undervolting_on_alder_and_raptor_lake/

Would be great to get those bios settings locked to a minimum value of 100 to avoid impacting system longevity :

Core/IA VR Settings
- AC Loadline
- DC Loadline

Hoping Asus will let us reduce those insane temps (got package temp at 97 degrees on a medium range ressource demanding game)
I ihave applied the -30 undervolt in bios better than nothing .

The new 306 bios says you can undervolt till -80mw, but it does not work, tried everything. Hopefully we will see more undervolting settings in future upgrades to the bios.

I reduced also in bios all performance cores to 4400 Ghz. My games don't need the extra power for the moment. Will see in the future.

Bios Update No. 307 was released today March 15th - 2023, and it actually allows undervolting to -80 so they fixed the bug.
Hope they allow further undervolting if it's stable.

Thanx for the info I will update as soon as possible 🙂

Update : They removed "AI Tweaker" settings in bios 307. But the good news is everything seems unlocked for XTU or Throttlestop. Thanx Asus.
Check that you don't have "Virtual Machine Platform" enabled in Windows Features or the bios undervolt will not apply.
