BIOS/UEFI Settings
Intel Settings
Intel Speedstep or EIST: OS conrolled clock speeds. Older
Intel SpeedShift: Cpu controlled clock speeds. Newer
I disable SpeedStep/EIST and use SpeedShift to let CPU control itself.
I prefer undervolting lately since clock speeds are not everthing and IPC (instructions per clock) plays a big role in performance. Lower -0.010v and test. Go lower if system is stable.
Don't forget to test NVME SSDs for instability too.
Disable Hyper-Threading if you don't really need it. Cpu runs cooler. My 13700K performs at least 10c cooler with NH-D15.
Use Intel TurboBoost but disable motherboard manufacturer overclock settings. They push too much voltage and generate too much heat as a result.
Disable Asus Multicore Enhancement
Disable MSI Enhanced Turbo
