This model consistently operates at 4.7 GHz.
I just changed my bios settings on my Asus ROG STRIX Z390-F. It’s been consistently hitting 4.7 GHz even when idle, and it stays that way whether I enable XMP or not. I disabled XMP before and kept multicore enhancement off, but it still doesn’t change. I also set Windows power plans to balanced and turned off AI overclocking. Anyone know why it’s stuck at this speed?
Two factors might cause the CPU to run at a steady pace: BIOS or Windows settings. The BIOS usually manages CPU speed, but it can sometimes be turned back on accidentally. Look for terms like "OS handle cpu" in the BIOS menu. If not found, open the control panel, select Power, then Advanced Options, CPU Power Management, and adjust the minimum and maximum CPU states to your preference.
The 9900k runs at 3.6ghz with a turbo option up to 5.0ghz, likely reaching around 4.7ghz. A recent BIOS update might have adjusted or fixed the boost/clock configuration. Make sure to verify if auto/AI overclock or CPU boost clock is enabled. If gaming mode is active, it will also utilize the turbo speed above the standard setting.
Referenced a power management feature using the icon mentioned.
Setting the maximum to 99% turns off Intel Turbo Boost. This will keep the processor at 9900K with a top speed of 3.60 GHz. Not advisable. Intel CPUs will increase to full performance if they need work. Open Task Manager, go to the Details tab, and click CPU to manage background tasks. Something is running quietly but not actively.
