Hello, I've just tested some benchmark at 400Mhz and 600Mhz and the performance outputs the same. I think this options aren't working on Maixduino yet. https://github.com/PaulStoffregen/CoreMark Thanks Screen Shot 2019-08-07 at 1 03 05 PM Screen Shot 2019-08-07 at 1 04 19 PM

`void setup() { sysctl_cpu_set_freq(F_CPU); }

void loop() {

}`

Are there any side effects? I dont know.

Indeed, I have looked into the source code and the menu entry does not attempt to change the CPU frequency anywhere. It only changes the SystemCoreClock constant but it is not used anywhere, not even in the millis() implementation.
