Wattman is part of AMD drivers. Open up AMDs Radeon Settings app and click the Gaming tab, then Global Settings, and finally the Global WattMan tab.

Who is the best for vega ? wattman or afterburner ? thanks .

Wattman + overdriventool + notepad with regedit are the best

Thanks for this information. What does notepad mean?

I assume it means you get edit the registry file with notepad to customize clocks, voltages, etc.. Well that's what I did anyway Tongue
