Thats what most people expect when undervolting, but apparently on AMD new CPUS (and GPUs) there is a new system that just throttles back performance if it senses volts are not enough. So do check performance before and after applying undervolt
Interesting, so in future on AMD tech I will monitor clocks/performance like a hawk when underclocking to make sure they stable.
Still it doesnt mean undervolting will definitely cause that, if the cpu can handle it then it will be the same as before lower temps and potential more performance.
