My CPU(FX9590) clock speed stays at 1.37 GHz all the time even while gaming, but my maximum frequency is able to reach 4.72 GHz at most.
I tried to change the clock speed through AI Suite II(I am using Asus Formula Z as my Mainboard) but it didn't help at all.
My energy scheme is on high performance and I never changed it, so it has nothing to do with this.
