Dynamic Vcore vs AMD Manual Overclock

Hello guys, i want to overclock my ryzen and i have 2 options that let me set a voltage value on my bios (b450m ds3h), Dynamic Vcore wich let me introduce an offset of voltage and AMD Manual CPU Overclock in wich i can introduce an specific value of voltage and cpu mhz. Wich one should i use? thanks!

Depends on the CPU. On Zen 2, stick to PBO and dynamic Vcore. On older Zen and Zen+ CPUs, use manual.

PBO is itself, an overclock. It just doesnt go past the stated max frequency, which in other words means single thread performance is not going to improve but max thread performance will.

 

So instead of doing 4.3GHz peak and 3.9GHz sustained on a 2700x (just an example for the sustained clocks), PBO can turn it up to 4.3GHz peak and 4.1GHz sustained (depends on level of PBO and temperatures of course).
