I recently built a brand new computer with an Intel i9-9900K and an Asus PRIME Z390-A, and am having some issues with the core speed. BIOS has been reset to default after I had made some brief changes to it and it has not fixed the issue. Speedstep and turbo is enabled. I notice in my Open Hardware Monitor + task manager programs that my core speed can jump from as low as 800-1000 mhz up to 4.8 mhz in seconds. This is with no load and the computer is on idle. I have power management mode set on balanced. I would really appreciate some help as im worried my components could be ruined because of this.
