Update your motherboard BIOS to the latest stable version
Install the latest AMD chipset drivers
Use a quality aftermarket CPU cooler
Ensure strong case airflow
Enter BIOS/UEFI and load optimized defaults
Disable Precision Boost Overdrive only if doing manual overclocking
Set CPU core ratio to a fixed all-core multiplier
Start with a conservative value such as 4.0 GHz
Set CPU core voltage manually
Start with a low safe voltage such as 1.25 V
Increase multiplier in small steps
Test stability after each change
Use Cinebench, Prime95, AIDA64, or OCCT for stress testing
Monitor temperatures with HWInfo64 or Ryzen Master
Keep full-load CPU temperatures below 85°C
Adjust voltage only in small increments if instability occurs
Do not exceed safe daily-use voltage levels
Tune LLC to reduce voltage droop if needed
Save each stable BIOS profile
Re-enable memory XMP/DOCP after CPU tuning
Test RAM stability separately with MemTest86 or TM5
If manual overclocking is unstable, use Precision Boost Overdrive instead
Set PBO limits to motherboard or custom values
Increase scalar only modestly if using PBO
Use Curve Optimizer only if supported by your BIOS
Recheck stability after every change
Restore defaults immediately if temperatures or crashes become excessive
