This article at AnandTech, http://www.anandtech.com/mb/showdoc.aspx?i=3190&p=13, says that for a quad, the FSB Overvoltage Control will require the max setting. Also there's an undervoltage of 0.2V from the BIOS set overvoltage. Anyone knows this is true and if this applies to EX38-DS4 boards as well?
