I/O jumpers ?

HI there , what i'm trying to do is get more FSB out of my Board untill I can unlock my XP chip ,
I'm running an ASUS A7V 133 bios is 1010.001
looking at my manual it talks about I/O Voltage settings
I have a 3.30 3.45 (default) and test mode.

it also states that it should be left on default unless process overclocking reuires a higher voltage .

first question is if what would it say to leave it on default unless more voltage is requires a high voltage when 3.45 is default and is the highest this setting goes too?

second what would be the pros and cons of moving the jumper to either 3.30 or test mode ?

I was tring to overclock my sytem to see how high I can go I have been able to get to 150 FSB with no problems yet and no mods done to the board.
I read else where that your PCI slots also overclock which I knew but if your able to get to something like 166 it defaults back to 33/66 (pci/agp).

Third what are some other ways to be able to get the FSB higher , I'm open to other options .
I plan on getting something to unlock the XP chip next month and I hope this will help as well.
what are s

some tricks people are using ?

3.3v is the standard for I/O voltage. I wonder why it defaults to 3.45...

This should probably be in amd motherboards:asus, shouldn't it?

Yeah It's an ASUS A7V 133 , I thought it was werid my self since dram voltage it 3.3 Volts , I wonder it this is why I kept killing cheaper ram
