After disabling the profile, the RAM will default to a low, stable frequency (e.g., 2133MHz or 2400MHz). Do not manually change the frequency higher.
AMD’s SMU (System Management Unit) handles P-state and overclocking. how to disable overclocking
On ASUS/ASRock AM5 boards, physical jumper OC_LOCK# tied to GPIO pin 47 can be asserted to ground, forcing SMU into strict compliance mode. After disabling the profile, the RAM will default
The BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) is the low-level software that initializes your hardware before the operating system loads. This is where the most permanent overclocking settings live. On ASUS/ASRock AM5 boards, physical jumper OC_LOCK# tied
Once inside, the interface varies by manufacturer (ASUS, MSI, Gigabyte, ASRock). Look for a tab or section named one of the following:
Some motherboards and third-party apps auto-OC:
echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo
lscpu | grep "MHz"
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
Before changing any settings:
