Actually, hardware support needs to be there for proper voltage controls for undervolting or overvolting, does not matter. The PWM and buck controllers plus associated logic chips need to be designed properly for either situation. To some degree, undervolting is more difficult to design into a system than providing overvolt controls. But yes, while your current hardware design might/does support undervolting, the reason it is not in the BIOS is due to validation testing and potential concerns with proper power delivery.

In regards to ASUS, the current 890GX EVO and the upcoming 8xx EVO boards fully support undervolting on Core VID and NB VID settings. One of the many reasons we are using 8+2/8+3 setups compared to similar boards with 4+1 setups.
