What it means
AMD's built-in way to let a Ryzen CPU boost harder and run a per-core undervolt. Tuned well, it gives real sustained clocks and cooler operation.
More detail
PBO (Precision Boost Overdrive) raises the limits the chip is allowed to push to; the Curve Optimizer trims voltage so it boosts higher at the same heat. The honest catch: push the numbers too far and you get crashes that look "random" for weeks until you connect them back to this. It's advanced-user territory — small steps, hours of stability testing, expect a few setbacks while dialing.
