well - is there a difference between programming voltage and operating
voltage? Maybe it's programmed at 12 but operates at 5? I'm guessing - I
don't know.

GigaByte. The motherboard itself is very good but there customer support

mailed them on the day the damage happened and haven't heard a blip yet.
