G7 7590 Undervolting
Good day. After installing new bios update, i can't undervolting my laptop anymore (intel xtu/throttle stop) due to new intel microcode (plunder volt vulnerability). Can i revert this change (bios downgrade doesn't seems to help - tried to 1.9.0 v)?
Or will be this fixed in next updates?

Solved it! Downgrade to bios 1.9 like you have (as I have tried a few times today with no avail) but then get into bios and click “reset to defaults” or whatever that option down in the bottom right corner is, then make sure to choose “reset to factory defaults”...not custom or any of those other options, factory....
got full use of xtu now, and I’m now on 1.11.1, it auto updated to that after a few resets for some reason, all works fine, maybe runs a little hotter than I remember, but that may go away, either way it doesn’t throttle now

Welcome to the Dell Community @LevokosM
Did you try uninstalling Intel XTU and reinstalling it???

Yep. Also i tried to restore from "windows restore point" (before bios update installation) and completely reinstall it. Still the same

same issue on the 5590, these 9750's need an undervolt badly, just about every review of these g series say "really really bad thermals, but just undervolt and you have a decent laptop." shooting themselves in the foot as this is the basis for many purchases, hopefully a work around soon (or maybe egg dell/alienware on to have an undervolt app for all their gaming systems)

The solution works perfectly.
I've also updated to v1.11.1 BIOS after downgrading to v1.9 and the voltage regulators still works. Version 1.12 is the one we should avoid.

No probs, go to dell’s driver downloads on dell.com, click the 1.12 bios update, there should be “see previous versions” or something like that on the same page as the 1.12 bios download page, download 1.11.1 (or whichever you like), then just save it to your computer somewhere (should only be 7mb) and click into it (a bios.exe file), that will take you through everything next time you reset, very easy, but after the bios is finished updating, then press f2 on startup (on the dell logo), and reset bios defaults to factory. That’s it

no need to revert to 1.9.0, stay at 1.12.0, just restore bios settings to reset to factory, it will re-enable undervolting.

Don't really need to downgrade back to 1.9. Just click on Restore Setting button in bios, choose Factory settings and the sliders will be enabled in XTU.
Thanks everyone.
