Why is my cpu overclocking

[Lukke]

Hi guys i just built my pc today with a r5 3600 and a B550m aorus elite. When i got in to bios i only activate xmp so i could use my ful ram speed i did nothing else. It said that my cpu was rundning at normal speeds but when i open Windows it atutomatically overclocks my cpu and its super loud please help i didnt download anything

It's called PBO. It allows the CPU to move to higher frequencies when temps allow it and load demands it.

It also sounds like you've got an aggressive fan profile running which is ramping the fans up with small changes in CPU load/temp. In the BIOS there will be fan options and you can adjust them to a more gradual profile if desired. Many motherboards will have something like a silent or quiet option you can select for the CPU and case fans.

It's supposed to. As the post above mentioned it's a performance feature of Ryzen processors.

 

What you're hearing is the fan, not the overclocking. If it's too noisy then adjust the fan curves. Turning off PBO (which you can do) will just limit your performance unnecessarily.
