I have the same board (minus the wi-fi) and same CPU.
I settled on a -0.125 undervolt and I just "enable" PBO in the "Precision Boost Overdrive" section (not the AMD CPU BIOS section). Leave everything else on "Auto"... Also set "Performance Enhancer" to "Default"... I think auto is Level 1 and we don't want this doing anything.

Also this score is achieved by disabling everything in my startup and running with my cooler at max... If I run this right now as is with everything in the background running I will score much lower.
Edit: Oof, that was interesting. I just ran it while browsing and doing stuff:
