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 2133MHz rather than the 3600MHz you paid for.

r/buildapc on Reddit: What is PBO and is it safe?
January 11, 2024 -
I’ve just upgraded my cpu and gpu and have been loving the increase in performance however it wasn’t as much as I thought it would be in the game I’m playing “the finals” I decided to look up a video of playing with the same cpu and gpu I have bought and they’re getting over 100 more fps than I am running the same settings, I asked in the comments and someone said to try PBO for my cpu. I am not sure what that is and am just trying to find out what it is and if it is safe and safe for components.
Also is there a way of achieving that fps naturally or just through certain settings?
This is the spec list https://pcpartpicker.com/list/b9xdMV
And this is the video I’m referring to https://youtu.be/GFIzMMjrI2E?si=PGMHZG-l1rTyfyEA

[SOLVED] - Does PBO degrade the CPU? | Tom's Hardware Forum
April 17, 2020 - So long as it's able to reduce clocks and voltage as the cores heat up with a heavy processing load the boost algorithm is going to follow the FIT table values fused in at the factory to keep the processor 'safe'. The way to assure it can do that is to leave voltage and processor multiplier in AUTO, or maybe a very slight negative offset for voltage. Doing PBO right means never putting either of them to fixed values.

May 27, 2025 - ASRock initially dismissed reports connecting their motherboards to the problem as 'misinformation', all the while supplying a new BIOS to address boot-up and memory compatibility issues. Affected users had no other choice but to RMA their broken CPUs. According to new details from Tech Yes City, the problem stems from the amperage (current) supplied to the processor under AMD's PBO technology.

AMD Ryzen Master software question. :: Hardware and Operating Systems
Keep in mind that if you're using a Zen2 or Zen3 processor (not sure if Zen and Zen+ even have Auto OC option) that PBO isn't exactly safe if PBO's scalar setting is changed from 1X mode, as anything higher will override the default health management of the FIT, which would allow for higher voltages than what would normally be allowed as safe based on the current state of the CPU (CPU load, current draw, etc.)
