The actual BIOS layout and options available will change depending on the motherboard manufacturer so it's hard for me to give you an exact template, but I can still point you where to look for one. Usually you can find a template with some of the basic overclocking settings on your mobo company's forums. 3.4 is a reasonable target to start with, you shouldn't have to raise your vcore, set that to 1.2v straightaway. I'll follow up with some more information soon. The v8 can probably handle an overclock up to 4ghz but it'd be a little hot.
