BIOS Downgrade and Undervolt

2020-11-21, 18:29 PM

Hello!

I have an Ideapad 330-17IKB (81DM) and I want to undervolt my CPU. I used ThrottleStop and nothing happened, then I used XTU and I saw that core voltage offset is grayed out. I don't have the latest bios update but last time before I updated my bios XTU wasn't grayed out. 

The undervolt is locked by bios, am I right?

Is downgrading the bios only the single way to get back the undervolt? If it's the only way, where can I get older versions of the bios?

Thank you!
