The most that you are going to get out of that CPU on air is roughly 4.0 Ghz......if you are still using the stock air cooler that comes with the CPU I would not even think about making any adjustments in the BIOS at all, leave them alone, as the stock cooler was engineered to dissipate the heat of that CPU at stock clocks and voltages.
Now that that is out of the way, if you want to hit higher than 4.0Ghz you are most likely going to have to throw some volts at it and you will want to look at water cooling to obtain a 4.2/4.3 Ghz OC. For anything higher such as 4.6Ghz.....you are going to need sub zero cooling like phase change or LN2. I had to cool my 1090T to -55C to hit 4.6Ghz.
Can't tell you where to find your FSB or CPU multi info because you haven't stated what motherboard you have.
