I have built a PC with a Ryzen 7 9800X3D with 6000MHz CL30 DDR5 on an Asus ROG Strix B650E-F Gaming Wifi Motherboard.

In the BIOS i have enabled EXPO, but there is another pverclocking / enhancement option which i dont understand:

Instead of leaving my CPU settings on “normal” there is an option to enable “PBO Enhancement”.

This isnt buried deep in the AI Tweaker settings or any overclocking menu but is instead listed on the first BIOS page. So i guess this is intended to be enabled by a broad range of users instead of only overclockers.

I tried to find out what exactly happens when turning this on, but on YouTube i didnt manage to find any good explanations.

Either it was some overclocking guide or an old video about Ryzen 7000 or 5000.

This video claims that enabling PBO reduces temperatures AND improves framerates, however this does not make sense to me.

If the CPU does not boost as high to run a bit cooler, how could this result in better results in games?

TL DR: What does PBO enhancement do with my 9800X3D on my Asus motherboard and should i enable it?

Does it just limit the CPUs temperature target or is more overclocking involved?

If so, does this impact the CPUs lifetime?
