FSB voltage question.

I have a question. I can run my q9300 at 3.15 (420x7.5) on stock fsb and nb voltage. I have to go +.2 on fsb to get 3.2 (427x7.5). I haven't done alot of overclocking but I find it strange that I would have to move two tenths to get 50mhz. I want advice on if that extra voltage could be a problem or is the 50mhz not even worth it. I guess what I'm saying is I want the most performance I can get but I don't want to take unnecessary risk. Thanks for any incite anyone can give me.
 
It's not necessarily that the northbridge needs .2V more to gain 50MHz as it is that it simply can't go any higher than 420MHz on the FSB with stock voltage. Chances are you could raise your FSB even higher with that 0.2V increase and still be stable with regards to the northbridge.

As for whether or not the increase will be a problem, the answer is that it won't. You're using a perfectly safe voltage.
 
So then what's the difference between fsb voltage and nb voltage? I've tried moving up the nb a notch and it hardlocks loading windows.
 
Ah, sorry. I thought you meant northbridge voltage when you were talking about the FSB termination voltage. The same comments I made apply to either one though. You simply needed more voltage to go higher. As for the differences between the two, they are simply voltages used for different things.
