WARNING! Using a higher voltage may help when overclocking but may result
in the shortening of your computer component’s life. It is strongly recommended
that you leave this setting on its default.

The onboard audio CODEC may be enabled or disabled using all of these jump-
ers. Disable the onboard audio CODEC if you are using an ISA or PCI audio card
