Godmyster, what kind of help do you need? Do you have any problems with your rig? Or you want quick (or complete) OCing guide? Please ask more detailed questions, not like "I want to know all about UD5, what I didn't know yet. Wanna anyone help me?".
You can easily go for 3.8-4.2 Ghz on good air, up to 4.66 (222 QPI) on water, and even more on extreme cooling.
I am on Extreme, so can't advice you what BIOS is better. Try last final F5 and if you wouldn't like it, try read this topic from the beginning.

ReverendMaynard, QPI/Vtt higher then Vcore is needed for working combination of low CPU clock and high Memory multiplier, due to need of 2xMem Uncore multiplier. For example, in my 24/7 profile (193x21, Mem 10x, Uncore 20x) i need 1.3750 Vcore and 1.495 QPI/Vtt for 12h Prime stability.
