What vcore is your bosting to? Also what is your single core boost and cinebench score? I think my light core work load boost is not working right the clock speed is all over the place form 3-4.5 peak but stays in the 3.8-4 range and scores about 512. all core cinebench holds a rock stable 4.35 gets about 13600
Your score is right on the money.
With latest agesa I wanna say it's like 1.38v full load, maybe up to 1.41 or so. Im ok with that. AMD designed these to go that high.
