Increasing the CPU Boost Clock under "AMD Overclocking > Precision Boost Overdrive" does not work.(Tested with Ryzen 7600X and newest 3.20 bios)

When I set +200 MHz there, my CPU still only boosts to 5450 MHz (AMD default)

What does work is, if I use the software SMUDebugTool. Inside this software is a PBO tab, that allows for FMax override. Once I apply the boost override there it works and the CPU boosts up to 5650 MHz.

Please fix the bios option and make it work.

Software used to troubleshoot:

SMUDebugTool (to override FMax)

HWiNFO (with sensors to monitor effective core clocks)

OCCT (with stability test > core cycling with the SSE instruction set, to load one core at the time and check clock speed)
