- What is PBO and is it safe? : r buildapc - Reddit
PBO stands for Precision Boost Overdrive It's basically the CPU looking at available power and thermal overhead and deciding that it can use some additional voltage to override the default maximum clockspeed It is completely safe Needs to be enabled in the BIOS And while you're there, make sure that XMP is enabled, as a LOT of folks don't realize that's necessary so their RAM is running at
- PBO Limits: Disabled vs Manual? : r overclocking - Reddit
Pbo limits set to disabled keeps the 3 values at factory limits defined by the cpu, set to motherboard for crazy high limits set by the mobo manufacturer related to vrm supply limits, set to manual to define your own
- What is Precision boost overdrive and Core performance boost . . . - Reddit
PBO is basically some automatic overclocking, it increases or decreases the limits of the Ryzen Boost algorithm Core performance boost should be enabling the Ryzen Boost algorithm This modifies the clock speed and voltage the processor runs at a thousand times a second to deliver higher performance than at the base
- What the hell is PBO for Ryzen? : r Amd - Reddit
PBO is not an on off setting It unlocks three settings related to power consumption - PPT, TDC, and EDC That's power consumption, sustained current, and short-term current The defaults for the 5900X are 142W, 95A, and 140A, respectively If you reduce those values after turning on PBO, you will reduce your performance

- MSI PBO - What are the different modes? : r Amd - Reddit
For 65W processors like your 3700X, PBO enabled would mean PPT=128 for example I forget what the EDC and TDC default values are, but they're probably reasonable around 100A or less when temp constrained Enhanced modes are PBO presets that change EDC, TDC, and PPT to whatever values MSI deemed "appropriate" for those levels
- 5800X PBO settings. . . ? : r overclocking - Reddit
It can be better - going negative with PBO values should allow for keeping the boost clocks even longer and fans even more silent That aside, good job!

- ZEN 3 PBO and Curve Optimizer Tweaking Overclocking Guide
By unlocking PBO limits you are violating AMD’s stock configuration and therefore invalidating your Warranty Even though this guide is aimed at everyone, I am expecting you to at least know some of the basics about how ZEN cpus work, this includes PBO, PBO limits, navigating BIOS, troubleshooting potential issues that arise, etc Some of the things in this guide will vary from CPU to CPU due
