A performance boost can be achieved with just a few clicks — without the need for traditional overclocking. AMD’s Precision Boost Overdrive (PBO) provides a simple way to enhance Ryzen CPU performance. Building on the existing Precision Boost technology, which automatically increases clock rates based on load, temperature, and power supply, PBO allows for even more generous operating conditions.
The processor can run longer and more frequently in the more powerful Turbo mode. If you wish, you can also use the so-called “Curve Optimizer” to reduce voltage (undervolting) and further improve efficiency.
In many cases, motherboards already come with profiles for AMD’s PBO – for increasing the boost clocks, for example. The default settings simplify performance tuning.

Depending on the processor, motherboard, and cooling, PBO can noticeably boost performance. In tests with a Ryzen 7 7700X, multi-core performance in the popular Cinebench CPU benchmark improved by about eleven percent, with a 2.6 percent gain in single-core performance. The current Ryzen 9000 series benefits especially, as it works more efficiently and offers higher thermal headroom. However, a quality air or water cooler and a motherboard with a stable power supply (VRMs) are important.
AMD’s Precision Boost Overdrive (PBO) can tickle more performance out of the chips in Ryzen processors relatively easily – provided there is good cooling.

PBO can be activated either directly in the BIOS or through AMD’s Ryzen Master desktop tool. Many motherboards come with ready-made PBO profiles, including higher boost clocks or customized temperature limits. The Curve Optimizer function lets you optimize the processor’s voltage, which can reduce heat and fan noise (and potentially even increase clock speeds).

Advanced users can also manually adjust the PPT, TDC, and EDC parameters, which determine the maximum amount of power the processor is allowed to consume. In practice, however, the motherboard’s capabilities usually set the limit. In conclusion, if you have a modern AMD Ryzen processor and a solid system with good cooling, you should definitely give PBO a try. It’s a simple and safe way to get more performance from your system (without traditional overclocking).
