We’re rolling out the new feature to our full X670 and B650 motherboard families through BIOS updates, starting first with our ROG Crosshair and ROG Strix X670E boards. The first step is to update your motherboard with the latest firmware. In this guide, we’ll walk you through the steps and look at how PBO Enhancement affects CPU performance. All it’ll take is a BIOS update and a few quick settings changes. Our updated PBO Enhancement BIOS feature makes it easy to limit the temperatures you’ll see with your new Ryzen CPU in heavily threaded workloads. However, we know that many power users out there will take advantage of all the cores and threads of their new Ryzen CPU, and they’ll do it on a regular basis. During everyday operation, light workloads, and while playing most games, you’ll typically see much lower CPU temperatures. What’s more, you’re not actually likely to see the maximum 95° Celsius temperatures until you initiate a workload that engages all the CPU cores. Your CPU has self-imposed limits that prevent it from reaching temperatures that are actually harmful. To be clear: AMD assures its customers that its latest chips can operate safely at their stock temperatures.

With just a few clicks, you’ll be able to dramatically lower your CPU temperatures-and maybe even increase performance and reduce fan noise in the process.

To put you in control, we’re rolling out a BIOS update for our X670 and B650 motherboards with new options for our PBO Enhancement feature that make it easy for you to balance thermals and performance. This means that you might see higher CPU temperatures than you’re used to in your new AMD Ryzen-powered machine.

These new chips dynamically take advantage of available thermal headroom to give you higher clock speeds. AMD’s latest Ryzen 7000-series CPUs push the limits of performance farther than ever before.
