MCE on Asus boards can actually be quite useful providing you still set the voltage manually. Leaving it on with some boards means that you don't have to alter the power settings to avoid power based throttling. Manually setting the voltage overrides the voltage MCE would try to set, so it's still critical to change this.
This is the case for many Asus boards, but it may not be the same on others or boards from different manufacturers.
