    How can I get the current boosted multiplier of my Ryzen CPU?

      Hello,

       

      I'm writing a program with which I want to read out the current value of the multiplier of my Ryzen CPU. However, I only found out in the document "PPR for AMD Family 17h Model 01h B1" that I can read out the P-state via MSRC001_0061, which indicates the current non-boosted P-state. This is in my case MSRC001_0064 and by (CpuFid / CpuDfsId) * 2 I only get a multiplier of x31.25.

       

      How do I get the current boosted p-state, so I can calculate the current boosted multiplier (x35.0), such as CPU-Z or AISuite 3 from Asus?


      Best regards
