How much voltage is too much?
Key elements include balance and intensity. PBO typically uses around 1.5v, but it depends on the situation. If it feels excessive, adjust accordingly.
It varies based on the FIT result. Typically around 1.3250v from a certain count tested. Most OC communities will settle near this figure. Some recommend 1.3, others 1.35. The Stilt report from OCN notes about 1.3250v is the standard average for Ryzen 3000 models.
Even with a stable CPU temperature, it's still important to ensure proper cooling.
Activate PBO using stock PPT, EDC, and TDC settings; leave others automatic. Execute Prime95 128k FFT with in-place unchecked and observe the SVI2 TFN sensor. This will provide your FIT measurement. Once you exceed the safe voltage range, it’s worth considering sub-ambient cooling in my view. You’ll notice a gain of about 100MHz at 1-2 FPS in games. Aim for around 1.30v for optimal performance. Degradation remains difficult to quantify; no one can predict how long a CPU will last under these overclock conditions.
