I have the 3900x and Hero III, hardly boosts past 4470
attached is a screenshot after running the computer straight for 2days, highest recorded boost (1000ms poll interval) is 4.467MHz
not matter how I config the bios, all optimizied defaults, pbo on/off, manually setting pbo settings, it never goes to 4.5 or 4.6.
guess there not much we can do except wait for new bioses with new AGESA
