    Voltage selectors are for raising or lowering input voltage to devices according to their needs and specs. There are always variances above and below the standards. Think of it as a means to "fine tune" the interaction of the components of your system. Use with caution unless you like the smell of fried circuitry.

    3.3V is the standard these days for almost all devices in a computer. The advantage of being able to vary the voltage is to try to increase stability, compatibility, and performance between all the deivces that make up a computer.

    Get a fire extinguisher.

    The voltage selector is a delicate adjustment, .1 or .25 volts at a time in most cases. It is used to "smooth" out the performance of your components, not to try to turbo-charge them.

    Example:

    When I was overclocking my rig I discovered that the NIC would cooperate better with the elevated FSB if I nudged the voltage to 3.4. The PCI bus spec runs as a fixed percentage (33%) of the FSB. Because I raised it I had to "help" the NIC along to also run at a faster speed than it was designed to.
