[SOLVED] Asrock Fatal1ty X370 ITX

The BIOS says it will support the new chips but I am wondering if it offers PBO for the 2000 series and 3000 series. I have BIOS 4.6 installed for the 2600 and PBO cannot be turned on.

AMD Precision Boost Overdrive (PBO)
AMD's Extended Frequency Range and Precision Boost technologies garnered quite a lot of interest when they were announced in 2017. Although these technologies did work as advertised, the performance gains were too meager to get anyone excited enough about them. This changes with the launch of the AMD Precision Boost Overdrive (AMD PBO) feature with AMD 400-series chipsets. Already tried and tested to great effect on the X470 high-end platform, AMD PBO will be available on all B450 motherboards as well!

Precision Boost Overdrive essentially combines the Precision Boost 2.0 and Extended Frequency Range 2.0 to deliver elevated performance as and when needed. You will need a Ryzen 'X' processor and a 400-series motherboard to leverage it. While the AMD B350 chipsets do auto-overclock 'X' CPUs to an extent, the B450 chipset's AMD PBO ability allows for much better performance gains when using a Ryzen 'X' processor.
