My advice to you NomNom would be to have a look at the steps in this guide: http://www.techreaction.net/2010/09/07/3-step-overclocking-guide-lynnfield/
Every single chip is different and needs different settings to achieve different results.
1.45 is apparently the maximum safe voltage (I thought it was 1.4v so I was mistaken). Many people manage 4.0ghz on around 1.3v and some chips do need around 1.4v, but it depends entirely on the individual chip. Mine is stable at 1.34v for instance.
Nomnom: Have a look here as a good example of some overclocks that guys have achieved. Its interesting to see the huge disparity in voltages. For instance, poyyiee achieved 4ghz on only 1.216v (lucky bastard has a great chip!) and dog5566 needed 1.328v
Some crazy people are using more than 1.5v in that thread, but I'm guessing it was just to achieve the high clocks and not to run 24/7

@NomNom, set OC from CPU-Level up to manual or disabled. i.e. Disable all the Auto overclocking crap.
You didn't disable the spread spectrums and enabled LLC in your screenshots.
A lower PLL voltage gives stability in most cases and lowers the heat generated. Your board is quite sucky if it can't undervolt the PLL...Set it manually to 1.8v so it doesn't overvolt it.
The difference between 1333MHz RAM and 1600MHz is negligible, if your CPU and board can run 180 bclk stably then you can try 200 bclk and that'll put your RAM at 1600MHz. Lets concentrate on the CPU OC for now. Corsair Vengeance isn't overclocking friendly either.
Uhmm if he's allowed to set 500 bclk in BIOS that does not mean it can run at 500 bclk. Different 1156/1366 boards do achieve different bclks. Most of the P55/H55 and X58 boards should achieve 200 bclk quite easily however.
The voltages I've suggested above are conservative and won't kill anything, don't get your panties in a twist...
Obviously once everything is stable you should try lowering the vCore and IMC voltage till it's unstable then up it 1/2 notches.
