Hello @jkbuha, I would like to ask what is the variable name for GPU Voltage Offset? I have a different laptop that I would like to undervolt but not sure whether it isor not.Code:GT Voltage Offset
Thanks,
twsps
Processor, VarStoreInfo (VarOffset/VarName)
Memory, VarStoreInfo (VarOffset/VarName)
GT, VarStoreInfo (VarOffset/VarName)
Uncore, VarStoreInfo (VarOffset/VarName)
Thanks for the tip. I have also noticed that I found two variables for overclock variables "Overclocking Lock" and "Overclocking Feature". Currently I have enabled "Overclocking Feature" and undervolting is working, what about the "Overclocking Lock"? What does it do specifically?If it's a Dell BIOS (which it sounds like it is) then yes - it's the GT Voltage Offset.
You should be able to amend some/any of the following:
Code:Processor, VarStoreInfo (VarOffset/VarName) Memory, VarStoreInfo (VarOffset/VarName) GT, VarStoreInfo (VarOffset/VarName) Uncore, VarStoreInfo (VarOffset/VarName)

Hi guys, I upgraded from Mojave to Catalina and nearly everything seems to work. I am having only 2/3 issue:
- screen brightness is at 100% and I can't change it at all (not even visible in the system pref pane), while it was working (even with fn buttons) with mojave
- audio jack not working (not sure if was working on mojave, but I don't use it at all so I don't really care about this)
- audio from speaker is low, and was low with mojave too, but this one is weird: I have layout 11 (flag injected with clover at boot) and I tried using combojack "fix" from the-darkvoid repo and it fixed everything (both jack was working and volume was high and clear), but after a reboot it's broken again. Running combojack fix again does nothing.
Am I the only one encountering these issue? I don't care about audio issues to be honest, but 100% brightness is killing my battery![]()
I have WhateverGreen 1.4.0 and AppleALC 1.5.0.I would check and update all kexts. Brightness issue could be because of outdated WhateverGreen.kext.
Audio could be fixed with new AppleALC kext, I use layout id 13 since Catalina, seems to work better.
