Hi, i just upgrade my cpu from Ryzen 7 3700X to Ryzen 7 5800X3D. I want to undervolting, but it seems no PBO setting on my motherboard (Asrock X570 Steel Legend). Does anybody know how to enable PBO on Asrock X570 Steel Legend?

There is no PBO under NBIO Common Options. In my X570 Steel Legend NBIO Common Options, there few option, such as : IOMMU, PCIe ARI Support, HD Audio Enable, (folder icon) SMU Common Options, Enable AER Cap, SRIS.

Hi Marcusfenix29,

PBO on X570 Steel Legend Bios menu , you can find on here :

on Bios Menu > Advanced > AMD Overclocking ( Accept Option Yes/ enter ) then you see there is PBO ( precision Boost Overdrive ) on section 3 from the top .

on PBO menu you can find any option that you want to the best set up for your Motherboards and Ryzen Zen3.

if you want PBO from Motherboards  Max Set up then you can select PBO Limits > Option >Motherboard.

The PBO only works in Zen3 Ryzen.

Thanks For using Asrock Brands!

unfortunately, there is no PBO ( precision Boost Overdrive ) option, only LCLK Frequency Control option under AMD Overclocking
