I/O voltage in BIOS?

[RIDGErace]

in Softmenu on my KT7, what is the I/O voltage? it can be selected and changed just like the core voltage. Will this let me overclock more?

I/O voltage is usually best left at default. In some rare instances, it can help stabilize an overclocked system by providing more voltage to the system/PCI/AGP cards and to the memory banks.
