01.The End of Aggressive Overclocking?
In 2026, both Intel and AMD already deliver their processors "at the limit" from the factory. Manual overclocking from 5GHz to 5.5GHz rarely results in an FPS gain that justifies the drastic increase in heat and power consumption. Nowadays, the most efficient technique is Undervolt + Overclock (increasing efficiency so the processor can maintain high frequencies for longer).
Don't do it Manually.

02.1. AMD: The Power of PBO
For Ryzen users in 2026:
PBO (Precision Boost Overdrive) is AMD's official way of overclocking. It analyzes the thermal capacity of your fans and motherboard to decide how far to boost the clock.
Tip: In the BIOS, enable PBO and use the Curve Optimizer with a 'Negative' value (-15 or -20). This reduces voltage, making the CPU run cooler and allowing it to hit higher clocks automatically.
03.2. Intel: Multipliers and Chipset
Unlocked K-Series Only:
If your Intel processor doesn't have a "K" at the end (e.g., i5-13400), the multiplier is locked and you won't be able to overclock.
For unlocked processors, adjustments are made in the BIOS by changing the CPU Core Ratio. Start by increasing +1 across all cores and use the Cinebench program to test if Windows doesn't blue screen under stress.
04.3. Enemy #1: Voltage
Never use Motherboard "Auto-OC":
Many motherboards promise one-click overclocking (OC Genie, AI Overclock), but they usually apply a dangerously high voltage (VCORE) to ensure stability. Prolonged use above 1.4V can degrade your processor's silicon, shortening its lifespan. In 2026, manual and patient overclocking is the only safe way to extract extra performance.
