you could but I've stated this before, not all chips are the same. I'm sure you've found it while you were reading up on guides... so depending on your piece of silicon, you may be able to hit high clocks with relatively lower voltages than others. Similarly you may even be able to run the lowest voltage possible on a mild overclock.
Again, I'd advise on going with a thread of your own since this is a discussions thread, your problem is more specific to your hardware and you can link your thread here, everyone else frequenting this thread can offer their opinions and/or experiences. You'll see others offer more info.
Not the same chip but I've managed to overclock my Q9550 system for the lowest possible voltage needed, In fact it was far lower than stock voltages. In order for me to accomplish that, I had to look high and low of what made what tick. Literally had to balance alot of voltages and timings as well as multipliers for achieving that feat.
Oh, and good luck
