Asus A8N-E Bios settings need help!

[titaniumx3]

This is my first PCI-E motherboard and some of the bios settings are confusing to say the least. Does anyone know what settings I should leave the Peg Link Mode options at? The settings are:

PEG Link Mode
PEG Root Control
PEG Buffer Length

All I know is that the PEG Link Mode setting overclocks the graphics card somehow, but the other two options I have no clue what they do. Any help would be greatly appreciated!

Do not touch any of them settings leave them at default, only use your bios for overclocking your processor. There are programs you can download to overclock your graphics card.
