[SOLVED] Why is my i9-12900kf under load only @4900MHz?

[rockscientist01]

Hello,

I 'm pretty much a noob when it comes to OC. Is it normal, that under load (prime95, cinebench R23, blender etc...) the CPU clock maxes out @4900 MHz? From the specs I was expecting 5100 MHz?

thanks
AO

The P cores under full load should be 4.9 and the E cores 3.7. Single core and all core turbo speed is different.

@rockscientist01 , the max frequency scales based on how many cores are really busy. Been that way for a ~long time.
