Nuc8i7hvk - How to undervolt cpu

Hi to all! Because it is the first time that i have to make such changes to BIOS, and i too have thermal issues, could someone please provide an analytical guide with all the changes that have to be done?

 

Firstly before doing anything should i keep Turbo Boost enabled and run Prime95 & Furmark for correcting thermal behavior and then apply any changes to the BIOS?

Then i just keep enabled turbo boost and apply -150vm in vcore or there are any other changes that have to be done?

 

After all that re-run Prime95 & Furmark?

 

 

 

Thanking you in advance!!

Just for clarity, when you say "I too have thermal issues" can you describe the system behavior that is leading you to that conclusion?

I just bought the unit and it's easily reaches 100 celcius in matter of seconds after boot with only running HWinfo!

When I say "I too have thermal issues" I'm reffering to the following thread

And I take it you have done the thermal conditioning of the TIM by running prime95 and furmark at the same time for burn-in of the TIM? If your CPU immediately hits 100C, undervolting is not going to do much for you.

Yes, you should do the burn-in first.
