PBO stops working after AMD EXPO profile is applied

Level 8

Hi. I posted recently about PBO on my B650E-I WIFI. Looks like i figured out what was wrong. I applied negative curve through PBO it works well then I turned on EXPO and the curve setting just stopped working. I tried to apply AMD ECO mode and the result was the same - no changes when RAM EXPO profile is applied.Can you help ? It's it a bios bug or some changes applied with enabling expo doesn't allow PBO to work?

  • Actually seems like I was wrong about PBO not workinng. It was just OCCT reporting incorrect numbers. Tried to use AIDA64 and found out that everything works as expected.
