PBO / Curve Optimizer (AMD CPU tuning)
Also searched as: pbo · precision boost overdrive · curve optimizer · undervolt cpu
What it does
BIOS-level boost extension and per-core undervolting on Ryzen.

The Compy Blackbook holds 174 graded entries like this one, judged against your hardware — and every change it does make is reversible, with the receipt to prove it.
